Wherein, the grain diameter of the PVC paste resin HG-1000F is 0.063-2.5 μm, preferably 1-2 μm, the grain diameter of the PVC tragic resin SB-100C is 25-50 μm, the PVC paste resin LF-51L has the molecular formula of- (CH2-CHCl) n-, n is average polymerization degree, CAS number is 9002-86-2, is polyvinyl chloride homopolymer, the grain diameter is 85-165 μm, and the powder is mixed with plasticizer and other auxiliary agents to prepare the PVC paste.
Dioctyl terephthalate (DOTP) LF-30, molecular formula C24H38O4, high efficiency as plasticizer in the invention, environmental protection, no toxicity, long thermal stability time, good compatibility with PVC polymer, low volatility, exudation, large capacity of extender, high brightness of product and other conventional advantages.
Compared with other common plasticizers, the modified polyester has the outstanding advantages of heat resistance, cold resistance, difficult volatilization, extraction resistance, flexibility, good electrical insulation performance, excellent durability, soap water resistance, low-temperature flexibility and the like in products, and the prepared slush molding has wider application range because DOTP does not contain phthalate and is not in the range of 16 phthalic acid-containing plasticizers limited by European Union and other countries.
Heat-resistant oil drapx 39(D39), CAS number: 8013-07-8, in the present invention, D39 is used as a nontoxic plasticizer and stabilizer, which can stabilize active oxygen atoms on PVC chains, act as a stabilizer, have good compatibility with PVC resins, low volatility, small migration, excellent thermal stability and light stability, good water resistance and oil resistance, and can impart good mechanical strength, weather resistance and electric resistance to products, and is nontoxic.
1.5-2 parts of dioctyl terephthalate plasticizer can be reduced by adding one part of D39 under the same conditions, other physical properties are improved, and the dioctyl terephthalate plasticizer is not volatile at the processing temperature of 300 ℃; 2-3 parts of D39 heat-resistant oil is added, so that the photo-thermal stability of the PVC composite material can be greatly improved, and about one third of the dosage of light and heat stabilizers in a common formula of PVC products can be reduced; after D39 heat-resistant oil is added, the slush-molded toy produced by the invention has unique heat-resistant, light-resistant and ageing-resistant performances and is not easy to fade when used outdoors.
The enamel toy has the characteristics of excellent heat resistance, good weather resistance, environmental protection and no toxicity, has good compatibility with PVC resin and has a certain lubricating effect.
The PVC viscosity reducer D80 has extremely low PVC aromatic hydrocarbon content, no odor, improved worker comfort, environmental protection and safety, can effectively reduce the viscosity of the formula of PVC paste resin, maintain longer viscosity stability, reduce the generation of bubbles, increase the dosage of fillers, enable PVC finished products to have smooth hand feeling, better anti-dirt adhesion, reduce the dosage of plasticizers and the cost of finished products, improve the ductility of PVC resin, and can meet the environmental protection requirement of export commodities: such as GSG, FDA and ROHS certification in Europe, the REACH registration environmental protection certification requirement is completed.
The dimethyl silicone oil KF-96-100CS as demolding agent has excellent properties, and the non-stick property of dimethyl silicone oil, rubber and plastic makes demolding convenient, clean and smooth surface and clear texture.
DNTXIB, 2, 2, 4-trimethyl-1, 3-pentanediol diisobutyrate formula: C16H30O4, CAS No.: 6846-50-0, DNTXIB is a multi-purpose plasticizer, non-toxic plasticizer without benzene ring, not merely dissolve with all general second grade plasticizer, especially can exert the best effect when cooperating with DOTP to use, can reduce the viscosity of the solution, increase the stability of the solution viscosity at the same time, pour into the small mould of the mould easily, mix with PVC resin easily, save the time before the extrusion molding of the injection at the same time, because the viscosity reduces in PVC solution, it is difficult to mix into the air, keep smooth and esthetic of the appearance of slush molding.
