Description

Technical Field

[0002] Antistatic resin is a polymer material with special properties. By adding antistatic agents or using special synthesis processes, it has the ability to prevent the generation, accumulation and release of static electricity. Its base resins are diverse, such as epoxy resins, polyester resins, polyolefin resins, etc., which can be selected according to different application scenarios and performance requirements. Antistatic agents include conductive fillers, polymer permanent antistatic agents, etc., which can achieve good antistatic effects through reasonable proportioning and processing with base resins. Antistatic resin has the characteristics of low surface resistance and fast charge dissipation, which can effectively prevent static electricity from damaging electronic components, precision instruments, etc., and prevent fires and explosions caused by static dust absorption and static discharge. It is widely used in electronic appliances, aerospace, packaging, textiles and other fields, such as electronic equipment casings, integrated circuit packaging materials, antistatic packaging bags, etc.

[0023] The present invention has the beneficial effects:

[0024] 1. The present invention provides a feeding mechanism to add the viscous base resin and the powdered conductive filler and additives separately, thereby avoiding the adhesion of the powdered raw materials and ensuring the accuracy of the added amount. The driving component drives the stirring blade to rotate to pre-mix the raw materials, thereby improving the dispersion uniformity of the conductive filler and additives in the base resin, reducing the feeding steps in the production process, and improving production efficiency.
