[0041] The product performance test of the foamed plastic obtained by using the above formula is as follows, linear ratio: 1.7; volume expansion ratio: 4.913; hardness: 75C; specific gravity: 0.16g / cm^3.

[0042] Above-mentioned formula is just a larger range value of each component in the formula, not concrete, is a preferred version of formula of the present invention as embodiment 2, and the formula of embodiment 2 comprise...

Embodiment 2

[0053] Example 2 gives the specific number of parts of each component of the formula, which is a more preferred solution. For the product obtained in Example 2, the performance test results of the product are as follows, linear magnification: 2.0; volume expansion magnification: 8.0; Hardness: 60C; specific gravity 0.09 g / cm^3.

[0054] A production process for producing copolymerized polypropylene foam using the above formula, the steps include: 1. Weigh the required raw materials according to the proportion of the above formula, and mix the main base material (polypropylene resin), processing aids, and initiators evenly and put them into 2. Mix through the internal mixer in step 1, and set the internal mixing temperature to 125°C. When the temperature reaches the set value, put the crosslinking agent and foaming agent into the internal mixer, and blank The temperature is set to 135°C, and the blanking time is set to 15 minutes; 3. Transfer the mixture in step 2 to the open m...

Abstract

The invention discloses a formula and a production process of a co-polypropylene foamed plastic. By using co-polypropylene as a raw material, the obtained foam product has the advantages of light mass, high strength, low cost, good heat resistance, degradability and easy recovery, etc., and has no influence on the environment. Meanwhile, resources are saved, the processing process is simple, and the processing equipment involves traditional machines, so that there is no additional increase of equipment investment, and the cost can be reduced to the utmost. With excellent heat insulation, sound absorption and noise reduction properties, the co-polypropylene foamed plastic is very suitable for home decoration.

Description

technical field [0001] The invention relates to a formula and process of foamed plastics, in particular to a formula and production process using copolymerized polypropylene as a raw material. Background technique [0002] Because of its light weight, good heat insulation effect, good cushioning effect, good insulation, stable anti-corrosion performance, and low price, foam plastics can not only beautify product packaging, but also provide cushioning protection for products, and are widely used in daily necessities In the fields of packaging, industry, agriculture, transportation, military, aerospace and other fields, basically all products in the market need to use foamed plastics. Traditional foamed plastics are made of EVA, PE, PS and other materials. , but traditional materials such as EVA, PE, PS, etc. have very large defects, high cost, cumbersome processing technology, cannot be degraded and recycled after use, cause great environmental pollution, and cause a great wa...
