Problems solved by technology

[0003] Although there are anti-static pearl cotton on the market, most of these anti-static can only be maintained for half a year - a year or so. Once the temperature is low in winter, the anti-static effect is very unstable. If it is used in electronic Product chip circuit protection, it is easy to short circuit, and then damage the product

Abstract

The invention relates to antistatic pearl wool and a preparation method thereof. The antistatic pearl wool comprises the following preparation raw materials in parts by weight: 100-155 parts of polyethylene, 3-5 parts of an antistatic agent, 10-19 parts of titanate modified calcium carbonate, 1-3 parts of talcum powder, 1-3 parts of a silane coupling agent and 10-20 parts of a mixed foaming agent,wherein the mixed foaming agent comprises a mixture of monoglyceride and butane, and the weight of monoglyceride accounts for less than or equal to 80% of the total weight of the mixed foaming agent;polyethylene particles, special anti-static water-soluble particles and the like are preferably selected to be mixed according to a certain proportion, a certain amount of butane gas and monoglyceride are introduced through a pressure pump to serve as foaming agents. Compared with the common anti-static pearl wool, the anti-static pearl wool has a better anti-static effect and the anti-static effect can be achieved for a long time.

Description

technical field [0001] The invention belongs to the technical field of pearl cotton, and in particular relates to an antistatic pearl cotton and a preparation method thereof. Background technique [0002] EPE pearl cotton has a non-cross-linked closed-cell structure. It is a high-foam polyethylene product extruded from low-density polyethylene (LDPE) as the main raw material. It is also called polyethylene foam cotton. It is a new type of environmentally friendly packaging material. Because it is composed of numerous independent bubbles produced by physical foaming of low-density polyethylene resin, it overcomes the shortcomings of ordinary foam rubber such as fragility, deformation, and poor recovery, and has good water and moisture resistance, shock resistance, sound insulation, heat preservation, and good plasticity. , Strong toughness, recycling, environmental protection, strong impact resistance, etc., also has good chemical resistance. [0003] Although there are anti...
