Abstract

The invention relates to a sponge with excellent fatigue resistance and a preparation technique thereof, belonging to the technical field of sponge products. The sponge with excellent fatigue resistance is prepared from the following raw materials in parts by weight: 80-120 parts of polylol mixture, 75-108 parts of toluene diisocyanate, 3.6-8.2 parts of purified water, 2.3-5 parts of carbon dioxide, 3-8 parts of dichloromethane 0.08-0.2 part of bis morpholinyl ethyl ether, 0.03-0.1 part of triethylenediamine, 0.04-0.1 part of tetramethyl propylene diamine, 0.1-0.3 part of stannous oleate and 2.8-4.5 parts of silicon oil. The sponge with excellent fatigue resistance,has the advantages of excellent stress relaxation, excellent comfort, favorable tearing strength, favorable low-temperature properties, high durability and excellent properties, mainly has very high fatigue resistance, and can be widely used on equipment for damping, cushioning and the like.

Description

technical field [0001] The invention relates to a sponge with excellent fatigue resistance and a preparation process thereof, belonging to the technical field of sponge products. Background technique [0002] Sponge products have been used in various fields now. It is flexible, light, and elastic. It can absorb and disperse external impact force by bending to achieve the effect of cushioning. It has thermal insulation, moisture-proof, heat insulation, sound insulation, anti-friction, anti-aging , corrosion resistance and a series of superior performance characteristics. But at present, most sponge products, especially those used for shock absorption, have poor fatigue resistance, so it is very easy to affect their durability. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art, and to provide a sponge with good shock absorption and buffering effect and excellent fatigue resistance and its pr...
