TL;DR: In this article, a zinc-containing anti-static flame-retardant type car plastic-absorbing material and a preparation method for its preparation was described. But the method was not discussed.
Abstract: The invention discloses a zinc-containing anti-static flame-retardant type car plastic-absorbing material and a preparation method thereof. The zinc-containing anti-static flame-retardant type plastic-absorbing material is characterized by taking the following materials: acrylonitrile-butadiene-styrene copolymer (ABS), linear phenolic epoxy resin, microencapsulated red phosphorus, basic magnesium sulfate whisker, nitrile rubber, mesoporous molecular sieve SBA-15, ammonium polyphosphate, melamine formaldehyde resin, kaolin, Sb2O3, dimethyl silicon oil, graphene, zinc oxide, sebacic acid, triphenyl phosphate, polyethylene glycol, styrene-maleic anhydride copolymer, palmitic acid, caprolactam, a silane coupling agent KH-560 and the like. The zinc-containing anti-static flame-retardant type plastic-absorbing material disclosed by the invention has the advantages that mesoporous molecular sieves and the linear phenolic epoxy resin generate bonding action, so that the heat stability of matrix resin is improved; the microencapsulated ammonium polyphosphate and antimony oxide/kaolin composite flame-retardant micropowder generate a synergistic effect, so that the flame-retardant effect is better; the graphene is added into the ABS resin matrix, so that the flame retardance and the heat stability of the resin are obviously improved, and the mechanical property is also higher; and the zinc-containing anti-static flame-retardant type car plastic-absorbing material is obtained.

TL;DR: In this article, the subject composition 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.
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.

TL;DR: PTE was tested for its ability to hydrolyze a series of biaryl phosphate esters, including mono- and bis-phosphorylated BINOL derivatives and cyclic phosphate tryters, and was shown to be able to catalyze the hydrolysis of the chiral phosphate triesters with significant stereoselectivity.
Abstract: The phosphotriesterase from Sphingobium sp. TCM1 (Sb-PTE) is notable for its ability to hydrolyze a broad spectrum of organophosphate triesters, including organophosphorus flame retardants and plasticizers such as triphenyl phosphate and tris(2-chloroethyl) phosphate that are not substrates for other enzymes. This enzyme is also capable of hydrolyzing any one of the three ester groups attached to the central phosphorus core. The enantiomeric isomers of 1,1'-bi-2-naphthol (BINOL) have become among the most widely used chiral auxiliaries for the chemical synthesis of chiral carbon centers. PTE was tested for its ability to hydrolyze a series of biaryl phosphate esters, including mono- and bis-phosphorylated BINOL derivatives and cyclic phosphate triesters. Sb-PTE was shown to be able to catalyze the hydrolysis of the chiral phosphate triesters with significant stereoselectivity. The catalytic efficiency, kcat/Km, of Sb-PTE toward the test phosphate triesters ranged from ∼10 to 105 M-1 s-1. The product ratios and stereoselectivities were determined for four pairs of phosphorylated BINOL derivatives.

TL;DR: In this paper, a flame-laminatable polyol in combination with specific amounts of specific flame-retardant, cross-linking agent and amine catalyst is used to obtain the titled foam having excellent laminating property, flame retardancy and heat-resistance.
Abstract: PURPOSE:To obtain the titled foam having excellent laminating property, flame- retardancy and heat-resistance and especially, excellent age stability, by using a flame-laminatable polyol in combination with specific amounts of specific flame-retardant, crosslinking agent and amine catalyst CONSTITUTION:The objective foam can be produced by compounding (A) a flame-laminatable polyol, (B) 5-40pts(wt) of an aromatic phosphate compound (eg triphenyl phosphate) as a flame-retardant, (C) <=5pts of a diol having a molecular weight of <=1,000 (eg diethylene glycol) as a crosslinking agent, (D) <=3pts of a nitrogen-containing compound having active hydrogen group (eg dimethylaminoethanol) as an amine catalyst, (E) an organic polyisocyanate, (F) a foaming agent and (G) a foam stabilizer, etc, and foaming and polymerizing the mixture
