Embodiment 1

[0044] Embodiment 1 and embodiment 2 use suspension method PVC and the processing mixing of various oils and fats in formula.

Embodiment 2

[0052] Add 100 parts of PVC resin by suspension method into the reaction kettle, stir and heat up to the predetermined temperature, add 1 part of hydrotalcite, tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid]pentaerythritol 0.5 part, 0.5 part of phosphite, 0.5 part of 2-hydroxy-4-n-octyloxybenzophenone, 0.5 part of oleic acid amide, 0.1 part of pentaerythritol, 0.2 part of inorganic pigment carbon black, continue to add zinc maleopimarate 4 1 part, 1 part of zinc stearate, 1 part of calcium stearate, after 10 minutes to 70 degrees temperature, spray and add 100 parts of premixed oil (propylene glycol adipate, trioctyl trimellitate, trimellitic acid 32 parts of three capric acid esters, 6 parts of diacetyl epoxy vegetable glyceryl oleate), increase the rotating speed and adjust the baffle plate, when the temperature rises to 125 degrees, the grease is completely absorbed, and the material remains dry. Then transfer to the cooling kettle at a high speed of 300 rpm, ...

Abstract

The invention provides a slush-molded PVC material for automotive trim skin. The slush-molded PVC material is prepared from suspension method type PVC resin, polymer resin, diacetyl epoxy plant triolein, Malay pimaric acid zinc, zinc stearate, calcium stearate, hydrotalcite, tetra[beta-(3,5-di-tert-4-hydroxyphenyl)propionic acid] pentaerythritol ester, phosphite ester, 2-hydroxy-4-n-octyl epoxide benzophenone, oleamide, pentaerythritol, inorganic pigments and an assistant. The invention further provides a preparation method of the slush-molded PVC material for the automotive trim skin. Suspension method PVC is adopted, powder completely and thoroughly absorbs polymer liquid resin oil, and the flowing state of the powder is kept. According to the method, dioctyl sebacate, adipic acid trimethylene glycol ester, trioctyl trimellitate and tridecyl trimellitate are adopted, no orthophthalic resin is adopted, the slush-molded PVC material is environmentally friendly, healthy and safe, and the international environmental health requirement is met.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a PVC material, in particular to a slush-molded PVC material for automobile interior skin and a preparation method thereof. Background technique [0002] The slush-molding process is to heat the back or the whole of the slush-molding mold (nickel shell) with leather texture, the mold and the powder box of the slush-molding powder are docked and then rotated or rotated while heating, and the plastic powder in the powder box falls naturally. Put it into the mold and melt it, and a leather-like skin with the same shape as the mold will be formed on the surface of the hot mold. Then the powder box is removed, the mold is cooled, and the skin is manually removed to obtain the skin. Each molding cycle is a heating and cooling process of the mold. The temperature rises from 40 to 50 degrees to more than 200 degrees and then drops to the original 40 to 50 degrees. It takes five or six minut...
