Lubricating oil composition

Abstract: PURPOSE:To obtain the subject high-lubricity composition which is a highly insulating oil, capable of providing the longevity and applicable to compression of a hermetically closed system by adding a specific phosphorus-based complex additive to an oil containing a polyalkylene glycol mixed with an ester. CONSTITUTION:The objective composition is obtained by adding an extreme pressure additive prepared by mixing two kinds of phosphoric acid triester-based additives having 200-400 molecular weight with one kind of phosphorous acid triester having 100-200 molecular weight to a mixture of a polyoxyalkylene glycol with a polyester oil as a base oil. Furthermore, tricresyl phosphate and triphenyl phosphate are preferably used as the phosphoric acid triester-based additive.

The average degree of polymn. of the vinyl chloride paste resin to be used is in the range of 2,500 to 4,000.

Drip type flame retardant styrene-based resin composition excellent in flowability and impact strength

Abstract: PROBLEM TO BE SOLVED: To obtain a drip type flame retardant styrene-based resin composition without generating mold deposits even when a continuous molding is carried out for a long time and excellent in flowability and impact strength by containing a specific rubber-modified styrene-based resin and a specific rate of an aromatic phosphate. SOLUTION: (A) 100 pts.wt. rubber modified styrene-based resin having 250,000-100,000 weight average molecular weight and containing ≤15wt.% resin having ≤40,000 molecular weight is blended with (B) 1-50 pts.wt. aromatic phosphate of the formula [(a), (b) and (c) are each 1-3; R 1 to R 3 are each H or a 1-30C hydrocarbon] such as triphenyl phosphate and preferably (C) 1-40 pts.wt. polyphenylene ether such as poly(2,6-dimethyl-1,4-phenylene-ether).

Pellet for producing flame-resistant resin material, and method for producing flame-resistant resin material

Abstract: PURPOSE:To obtain the subject pellet comprising a polyphenylene ether resin, etc., and a specific phosphate ester, low in load deflection temperature, easy in extrusion molding processing, excellent in handleability, and capable of imparting flame retardancy to the resin materials. CONSTITUTION:This pellet comprises (A) a polyphenylene ether resin or a polycarbonate resin and (B) a phosphate ester of the formula (Q1 to Q4 each is a 1-6C alkyl; R1 to R4 each is H, methyl; (n) is >=1; n1, n2 are each 0-2; m1 to m4 each is 0-3) (e.g. the ester of bisphenol A bound two or more triphenyl phosphate molecules, etc.,) and has a load deflection temperature of 120 deg.C under a flextural stress of 18.5kgf/cm . The pellets are blended with (C) a thermoplastic resin (preferably a styrenic resin) and subsequently melt-kneaded to obtain the flame-resistant resin material.

Rust preventive oil

Abstract: PURPOSE:To produce a rust preventive oil for removing solid lubricating surface treating on the surface of a steel sheet by incorporating a specific ratio of phthalic ester based or phosphoric ester based plasticizer to a base oil. CONSTITUTION:The rust preventive oil is prepared by adding 5-30 pts.wt. mixture of tricresyl phosphate, triphenyl phosphate, tributyl phosphate, diethyl phthalate or tricresyl phosphate with triphenyl phosphate or mixture of tricresyl phosphate with dibutyl phthalate into 100 pts.wt. base oil. When the rust preventive oil is applied on the solid lubricating surface treated steel sheet, the plasticizer in the rust preventive oil dissolves and removes the lubricating surface treating from the steel sheet and at the time of being coated with an adhesive, the steel sheet exhibits excellent adhesive power to a base material and is stuck strongly to the base material.

Flame-retardant flexible resin film and its laminate

Abstract: PURPOSE:To obtain the subject composition containing a flame retardant at a specific ratio, being transparent, having self-repairing properties and scratch resistance as well as flame retardancy. CONSTITUTION:This product is obtained by molding a transparent and flexible resin composition containing 1-50wt.% of a flame retardancy based on total weight of the resin composition and having self-repairing property and scratch resistance (preferably a resin composition consisting essentially of a crosslinked type non-yellowing polyurethane-based resin), preferably by a reactive bulk casting method. Furthermore, as the flame retardant, a combination of a phosphorus-based flame retardant and a bromine-based flame retardant is preferably used. The phosphorus-based flame retardant includes preferably triphenyl phosphate or trichloroethyl phosphate. The bromine-based flame retardant includes preferably diglycidyl ether of tetrabromobisphenol A and its oligomer.

Incorporated fiber and its production

Abstract: PURPOSE:To obtain an incorporated fiber useful for producing ultra-fine fiber and porous fiber, by making a polyester and a polyamide form a clear sea-island structure, comprising one of the polyester inactive to amide-ester exchange reaction and the aliphatic polyamide as an island component and the other as a sea component. CONSTITUTION:An island component having 0.2-0.8mum section area and 2,000-4,000mum volume is formed from one of (A) a polyester inactive to amide- ester exchange reaction and (B) an aliphatic amide and a sea component is composed of the other. The component A is mixed with an inactivating agent (n-octadecyl phosphite, triphenyl phosphite or triphenyl phosphate) to inactivate the residual catalyst in the polyester. A modified polyamide obtained by substituting an amino group at th end of a polyamide with any of groups formula I to formula III (R is H, 1-30C aliphatic, alicyclic or aromatic residue) is preferable as the polyamide of the component B. A block copolymer will not be formed between the component A and the component B in the fiber.

Production of refrigerator oil composition

Abstract: PURPOSE:To obtain a refrigerator oil composition having excellent insulating properties, especially useful for a freezing system having a closed type compressor in an excellent operation efficiency by dissolving an additive in a solvent, dissolving in a base oil and then removing the solvent. CONSTITUTION:Pentaerythritol is conventionally esterified with 2-ethylhexanoic acid in the presence of a catalyst such as titanium tetrabutyrate. The prepared reaction product is mixed with potassium hydroxide to neutralize the catalyst and purified by water washing with distilled water to give a base oil of an ester oil. Besides, triphenyl phosphate as an additive is dissolved in a solvent such as toluene at room temperature to give a 40% solution. The solution is added to the base oil of an ester oil so that the amount of triphenyl phosphate becomes 2.0wt.% and uniformly dissolved at room temperature. Then the solvent is distilled away by vacuum distillation to give the refrigerator oil composition having excellent insulating properties in excellent operation efficiency.

Halogen-free, liquid flame-retardant mixture for styrene homopolymers and copolymers

Abstract: Mixtures of triphenyl phosphate and dimethyl methylphosphonate, optionally in combination with hexamethoxymethylmelamine and/or melamine, are used as liquid, compatible flame retardants (flameproofing agents) in styrene homopolymers and copolymers. Samples containing these compounds achieve UL 94 V-O fire class.
