Problems solved by technology

On the other hand, due to chemical synthesis of traditional polyurethane products, some people subjectively feel that the product has a chemical smell, which affects the experience. At the same time, many manufacturers pay attention to cost rather than quality when selecting materials, resulting in widespread odor in polyurethane products. question
In addition, traditional polyurethane products cannot be degraded naturally, and can only be discarded by burning when the service life expires, which will cause air pollution

Abstract

The invention discloses a polyurethane composite material containing natural plant (coffee beans and tea leaves) compositions and a preparation method thereof. The polyurethane composite material is prepared from, by weight, a material group A including 30-40 parts of plant oil-base polyether polyols, 7-50 parts of special polyether polyols, 0-0.5 part of a catalyst, 0-2 parts of a cross-linking agent, 5-6 parts of amine-terminated polyether, 1.5-3 parts of a foaming agent and 10-20 parts of natural plants and a material group B including 20-50 parts of isocyanate. An obtained polyurethane product is degradable and can reduce air pollution; moreover, due to the fact that the natural plants are added, the obtained polyurethane product can send out natural smell to achieve a deodorization effect, the constant temperature performance of the product can be enhanced through the good space obstruction structure of the plant fiber, abandoned plant residues are recycled, and much energy is saved for the earth. In addition, the product of the technical scheme has good comfort.

Description

technical field [0001] The invention belongs to the field of polymer chemistry, in particular to a polyurethane composite material containing natural plant components and a preparation method thereof. Background technique [0002] Polyurethane is a common polymer material that is widely used in daily life. However, traditional polyurethane products have poor performance in terms of temperature balance, and usually show two extreme states in summer and winter, too soft or too hard, seriously affect comfort. Among them, the thermal conductivity of polyurethane is a problem that urgently needs to be solved for products such as polyurethane pillows and mattresses. The products produced by the prior art are usually stuffy, and users will feel hotter and hotter after prolonged use. On the other hand, due to chemical synthesis of traditional polyurethane products, some people subjectively feel that the product has a chemical smell, which affects the experience. At the same time, m...
