Embodiment 1

[0023] A production process of antistatic EPP foam plastic, the process comprises the following process steps:

[0024] 1) Initial expansion: use water vapor to heat the EPP foam plastic raw material to achieve the effect of initial expansion;

[0025] 2) Pressure material:

[0026] a) Pre-compression: apply 0.6 kg of pressure to the EPP foam after the initial expansion, and the compression time is 30 minutes;

[0027] b) Pressurization: After the pre-pressing is finished, apply a pressure of 3.8 kg to the EPP foam, and the pressing time is 500 minutes;

[0028] c) Pressure relief: After the pressurization is completed, apply a pressure of 2.5 kg to the EPP foam, and the pressing time is 80 minutes;

[0029] d) Constant pressure: After the pressure relief is completed, adjust the pressure value to 1.6 kg, and the constant pressure time is 60 minutes;

[0030] 3) Feeding: inject the EPP foam after pressing in step 2) into the mold, and prepare for molding;

[0031] 4) Expan...

Abstract

The invention relates to a production technology of anti-static EPP foam plastic. The technology comprises the following technological steps: 1) primary expansion; 2) material pressing; 3) material feeding; 4) expansion molding; 5) temperature preservation; 6) gradient cooling; and 7) demolding. Compared with the traditional foam plastic processing mode, a material pressing measure is adopted, so that the EPP foam plastic is pressed firstly, and then is rebounded so as to improve the structure intensity after molding; meanwhile, the EPP foam plastic has the anti-static property, and can meet the requirements of packaging and protecting high-tech electronic products.

Description

technical field [0001] The invention relates to the technical field of foam plastic manufacturing, in particular to a production process of antistatic EPP foam plastic. Background technique [0002] After the existing products are processed and produced, they are usually protected and packaged with foam plastic products. For high-tech electronic products, it is necessary to use anti-static foam plastic products for packaging. At the same time, the hardness of foam plastic products is also required to prevent static electricity from affecting the performance of high-tech electronic products, and at the same time to avoid external impact on high-tech products. Destruction of electronic products. However, traditional foam plastic products have low hardness and a certain degree of flexibility, which cannot protect the product well. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a foam production process with low p...
