Polyurethane used for making bicycle saddle

Abstract

The invention relates to polyurethane used for making a bicycle saddle, which comprises the following components by weight: 9-11 parts of component A and 40-55 parts of component B; the component A is an isocyanate-terminated performed polymer which is composed of 21-25% of diisocyanate and 75-79% of polyether glycol; and the component B is a hydroxyl-terminated performed polymer which is composed of 16-36% of polyether triatomic alcohol, 23-25% of chlorinated paraffin oil, 22-38% of talcum powder, 3-6% of colouring agent, 1-2% of anti-oxidant and 4-17% of inorganic nano-material. The provided polyurethane has the benefit effect that elasticity of the bicycle saddle can be effectively increased, riding comfort level of the bicycle saddle can be enhanced, buttocks muscular soreness of rider can be mitigated, and riding comfort level of bicycle can be increased.

Description

(1) Technical field [0001] The invention relates to a polyurethane, in particular to a polyurethane used for making bicycle saddles. (2) Background technology [0002] At present, with the change of people's pursuit of life, people's demand for health and environmental protection is increasing, and more and more people are beginning to achieve the purpose of ensuring their own health by riding bicycles. Bicycles have gradually become the Mainstream out-of-the-box means of transportation. The inner fillings of bicycle saddles are generally made of rubber to reduce the hip fatigue caused by the rider when riding a bicycle. However, most of the inner fillings of bicycle saddles now have insufficient elasticity, causing the riders After riding a bicycle for a long time, it will cause soreness in the buttock muscles, which is very uncomfortable. Now on the market, the elasticity of the bicycle saddle that can be effectively improved, thereby improving the riding comfort of the ...

Problems solved by technology

The inner fillings of bicycle saddles are generally made of rubber to reduce the hip fatigue caused by riders riding bicycles. However, most of the inner fillings of bicycle saddles now have insufficient elasticity, causing the riders After riding a bicycle for a long time, it will cause sore muscles in the buttocks, which is very uncomfortable

Now on the market, the elasticity of the bicycle saddle that can be effectively improved, thereby improving the riding comfort of the bicycle saddle, reducing the soreness of the cyclist's buttock muscles, thereby improving the polyurethane riding comfort of the bicycle has not yet been discovered, and it remains to be seen. to develop
