Abstract

The invention discloses a novel TPE8 plastic particle. The novel TPE8 plastic particle comprises SEBS, paraffin oil and a plastic additive, the novel TPE8 plastic particle is prepared from the following raw materials in parts by weight: 22-35 parts of SEBS, 22-35 parts of paraffin oil and 70-80 parts of a plastic additive, particularly from 22 parts of the SEBS, 22 parts of the paraffin oil, 70 parts of the plastic additive, particularly from 24 parts of the SEBS, 24 parts of the paraffin oil, 72 parts of the plastic additive, particularly from 32 parts of the SEBS, 32 parts of the paraffin oil and 77 parts of the plastic additive, particularly from 35 parts of the SEBS, 35 parts of the paraffin oil and 80 parts of the plastic additive. the plastic additive is a free radical scavenger, andthe invention relates to the technical field of plastic granules. The novel TPE8 plastic particles can be sprayed with paint, are aging resistant, are not easy to yellow, have good elasticity, are scratch resistant and have longer service life.

Description

technical field [0001] The invention relates to the technical field of plastic pellets, in particular to a novel TPE8 plastic pellet and a production process thereof. Background technique [0002] Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. As my country's economy has achieved sustained and stable growth, industries such as home appliances, automobiles, mobile phones, PCs, and medical devices have benefited from a favorable external environment and have also achieved rapid development. The development of downstream industries has further stimulated the demand for plastics. [0003] TPE is a thermoplastic elastomer material with high strength, high resilience, and can be processed by injection molding. It has a wide range of applications, is environmentally friendly, non-toxic and safe, and has excellent colorability. Soft touch, weather resistance, fatigue resistance...
