Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are rubber shock absorbing pads that are generally made of environmentally friendly rubber particles and foamed rubber particles plus adhesives mixed under high temperature and high pressure conditions, and people generally choose substances with strong polarity as Adhesive to improve the adhesive force of the adhesive, due to the low polarity of polyethylene, ethylene propylene rubber or butadiene rubber, the compatibility of the adhesive with polyethylene, ethylene propylene rubber, butadiene rubber is poor, making the adhesive The interface is easily damaged, which makes the adhesion between the environmentally friendly rubber particles and the foamed rubber particles and the adhesive worse, making the tear strength of the rubber pad lower, thereby shortening the service life of the rubber shock absorbing pad.

Abstract

The application relates to a special new material rubber shock absorber and a preparation method thereof. The special new material rubber shock absorber includes the following components in parts by mass: 25-35 parts of foamed polyethylene; 10-20 parts of polyurethane cotton; 20-30 parts of foam ethylene-propylene rubber; 25-30 parts of cork; 10-20 parts of adhesive; the adhesive includes the following components in parts by mass: 105-115 parts of polyphenyl polymethylene polyisocyanate; ‑105 parts; 55‑60 parts of phenolic resin; 0.5‑1.5 parts of organotin catalyst; 100‑120 parts of organic solvent; 20‑30 parts of ethylene vinyl acetate copolymer; 0.2‑0.8 part of ethoxyquin; N, N-bis(2-hydroxyethyl)-2-nitro-p-phenylenediamine 0.1-1 part. The present application has the effect of improving the shock-absorbing ability of the rubber shock-absorbing pad.

Description

technical field [0001] The application relates to the field of building materials, in particular to a special new material rubber shock absorber and a preparation method thereof. Background technique [0002] At present, rubber shock absorbing pads are generally made of a variety of rubber or plastics bonded under high temperature and high pressure conditions. The shock absorption principle of rubber shock absorbing pads is similar to that of springs. If the energy is not weakened, the sound will be directly transmitted downstairs, forming noise. [0003] The rubber shock absorbing pad can be laid between the floor and the floor, and can also be used as an intermediate product to bond a layer of layer material and lay on the surface of the floor. The vibration generated by the impact is weakened by the rubber shock absorbing pad, and the energy is absorbed and consumed. The impact of vibration and noise between adjacent floors is reduced, thereby providing people with a qui...
