AI Technical Summary

Problems solved by technology

Insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, and does not react with any substance except strong alkali and hydrofluoric acid. Compared with other materials, silica gel has better performance and can be adapted to various occasions. It has a wide range and is known as an environmentally friendly iconic material product, but the price of silica gel is high, the processing technology is complicated, the production cycle is long, and the leftover materials cannot be recycled. As a suction cup for daily consumables, using silica gel as a raw material is less cost-effective

Embodiment Construction

[0038] The example is a formulation system with styrene-ethylene-butylene-styrene block copolymer (SEBS) as the main body, supplemented by a small amount of processing oil, polypropylene (PP), antioxidant (AO), etc. Among them, styrene-ethylene-butylene-styrene block copolymer (SEBS) provides the main properties of the material, such as soft touch, elasticity, low temperature resistance, tortuous resistance, anti-slip, drop resistance, shock resistance, etc. White oil is used as a processing oil to improve fluidity and processability. Polypropylene (melt flow rate is 8g / 10min) can improve the plasticization and thermal stability of the material. Antioxidant AO.50 provides oxidation resistance and heat resistance. Aging.

Abstract

The invention provides a thermoplastic elastomer suction cup material, which is prepared from the components in percentage by mass: 70-95% of a styrene segmented copolymer, 2.5-15% of processing oil and 2.5-15% of polyolefin. The developed thermoplastic elastomer suction cup material is novel and excellent in performance, and has the characteristics of recycling, simple processing procedure, environment protection and non-toxicity, and a suction cup made of the thermoplastic elastomer suction cup material has excellent performance of slip resistance, low weight, comfortable hand feel and the like.

Description

Technical field [0001] The invention relates to the field of sucker manufacturing, in particular to a thermoplastic elastomer sucker material. Background technique [0002] The daily necessities suckers on the market are divided into materials, including PVC, TPU, traditional rubber, silicone, TPE and other materials. [0003] PVC stands for polyvinyl chloride, or PVC (Polyvinyl chloride) in English. It is a polymer formed by the polymerization of vinyl chloride monomer in peroxides, azo compounds and other initiators; or under the action of light and heat according to the free radical polymerization reaction mechanism. . Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. The material is an amorphous material. In the actual use of PVC materials, stabilizers, lubricants, auxiliary processing agents, pigments, anti-impact agents and other additives are often added; some toxic additives and plasticizers in PVC may ooze or v...
