Embodiment 1

[0009] The raw materials of this composite plastic product in this example are as follows: 40kg of polyvinyl chloride, 20kg of polyolefin resin, 10kg of mulberry wood chips, 8kg of nitrile rubber, 2kg of stearate, 3kg of epoxy soybean oil, 12kg of plasticizer, antioxidant Dosage 2kg.

[0010] The production method is as follows:

[0011] 1) Heat the polyvinyl chloride, polyolefin resin, NBR, stearate and epoxy soybean oil to 110°C and stir for 60 minutes, then add the mulberry wood chips, plasticizer and antioxidant Heated for 25 minutes to obtain the mixture;

[0012] 2) The mixture obtained in step 1) is poured into a mold, and the temperature of the mold is 40° C., and rolled into a composite plastic product with a thickness of 0.7.

Embodiment 2

[0014] The raw materials of this composite plastic product in this example are as follows: 45kg of polyvinyl chloride, 30kg of polyolefin resin, 12kg of mulberry wood chips, 10kg of nitrile rubber, 3kg of stearate, 5kg of epoxy soybean oil, 15kg of plasticizer, antioxidant Dose 3kg.

[0015] The production method is as follows:

[0016] 1) Heat the polyvinyl chloride, polyolefin resin, NBR, stearate and epoxidized soybean oil to 120°C and stir for 90 minutes, then add the mulberry wood chips, plasticizer and antioxidant Heated for 40 minutes to obtain the mixture;

[0017] 2) The mixture obtained in step 1) is poured into a mold, and the temperature of the mold is 45° C., and rolled into a composite plastic product with a thickness of 1.2 mm.

Abstract

The invention discloses a composite plastic product, and relates to the technical field of plastic products. The composite plastic product is prepared from the following raw materials in parts by weight: 40 to 45 parts of polyvinyl chloride, 20 to 30 parts of polyolefin resin, 10 to 12 parts of mulberry wood dust, 8 to 10 parts of nitrile butadiene rubber, 2 to 3 parts of stearate, 3 to 5 parts of epoxidized soybean oil, 12 to 15 parts of a plasticizer and 2 to 3 parts of an antioxidant; the composite plastic product is prepared by the following steps: heating the polyvinyl chloride, the polyolefin resin, the nitrile butadiene rubber, the stearate and the epoxidized soybean oil to 110 DEG C to 120 DEG C; stirring for 60min to 90min; then adding the mulberry wood dust, the plasticizer and the antioxidant, and heating for 25min to 40min to obtain a mixture; injecting the mixture into a mold, wherein the temperature of the mold is 40 DEG C to 45 DEG C; rolling the mixture to obtain the composite plastic product with the thickness of 0.7mm to 1.2mm. According to the composite plastic product disclosed by the invention, the problems that existing composite plastic becomes smelly when being heated and becomes moldy when being affected with damp are solved.

Description

technical field [0001] The invention relates to the technical field of plastic products, in particular to a composite plastic product used for automobile interior decoration. Background technique [0002] With the progress of society, people's living standards are getting higher and higher, and more and more cars have entered people's lives. Since our country is a large country with a large population, the consumption is also huge. The automobile industry is developing very fast, and the current automobile materials focus on environmental protection and lightweight, so composite plastics are mainly used for automobile interior materials. However, the existing automotive interior composite plastics have the problems of stink due to overheating and mildew due to excessive moisture. Contents of the invention [0003] The invention provides a composite plastic product, which can solve the problems of the prior composite plastics being heated, smelly, damp and moldy. [0004...
