Plastic marble grain surface and injection molding process

Abstract

The invention discloses a plastic marble grain surface and an injection molding process. Specifically, the invention relates to the field of plastic production, the plastic marble grain surface comprises a plastic composite material and marbling color master batch, the plastic composite material is characterized by being prepared from the following raw materials in parts by mass: 70 to 74 parts ofABS, 55 to 58 parts of PVC, 2.2 to 2.8 parts of antioxidant, 0.8 to 1.0 part of stabilizer, 16 to 20 parts of superfine powder, 51 to 54 parts of nano aluminum oxide powder and 26 to 28 parts of corundum fine powder. The marbling color master batch is prepared from the following components in parts by weight: 60 to 80 parts of PET, 5 to 10 parts of a pigment, 2 to 5 parts of a lubricant, 1 to 3 parts of a compatilizer, 0.3 to 1 part of a stabilizer and 0.3 to 1 part of an antioxidant. The marbling color master batch is added and mixed with the plastic raw material for melting, so that marbling-imitated plastic products with multiple colors can be obtained, and the tensile strength and the bending strength of the plastic products can also be improved.

Description

technical field [0001] The invention relates to the technical field of plastic production, more specifically, the invention relates to a plastic marble surface and an injection molding process. Background technique [0002] Plastic is mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. The finished product is solid, and it is a molten liquid during the manufacturing process. Therefore, it can be melted by machine heating, pressure can be applied to make it flow, and cooling can make it Solidified and formed into various shapes, this large and varied group of materials is called plastics. Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. [0003] The marble texture effect is white with black or dark patterns. At present, the marble texture effect is mostly achieved by preparing marble-effect glazes. However, the use of glazes is no...
