Abstract

The invention discloses a polyvinyl chloride slush moulding powder material which comprises the following components in parts by weight: 100 parts of polyvinyl chloride resin, 60-90 parts of plasticizing agent, 2.0-10.0 parts of inorganic-organic heat stabilizer compounds, 0.5-3.0 parts of antioxidant and light stabilizer and 3.0-15.0 parts of anticaking agent, wherein the inorganic-organic heat stabilizer compounds comprises 1.0-6.0 parts of a calcium-zinc composite stabilizer or a carboxylate compound of calcium or zinc, 0.5-6.0 parts of hydrotalcite and/or molecular sieve inorganic heat stabilizers and 0.5-3.0 parts of organic auxiliary heat stabilizer. The invention also discloses a preparation method and application of the polyvinyl chloride slush moulding powder material. The prepared polyvinyl chloride slush moulding powder material has good heat resistance and flowability and is suitable for rotational moulding or slush moulding forming; the product obtained through high-temperature rotational moulding can meet the requirements of the surfaces of automobile interiors on mechanical property.

Description

[0001] technical field [0002] The invention relates to a powdery polymer material for slush molding or rotational molding and a preparation method thereof, in particular to a polyvinyl chloride slush molding powder material and its Preparation. [0003] Background technique [0004] Polyvinyl chloride is a thermoplastic with excellent properties. Soft PVC skin has the characteristics of light weight, soft touch, leather-like surface and clear surface texture, and low cost. These skins are usually produced by slush molding method, and the slush molding powder used is a dry mixture of polyvinyl chloride resin, plasticizer, heat stabilizer, antioxidant, pigment, etc. At present, it has been widely used in automobile dashboard skins and other interior decoration skins. [0005] During the slush molding process, the mold temperature is generally 200-260°C, and polyvinyl chloride experiences high temperature for several minutes, so high requirements are placed on the thermal...
