Problems solved by technology

[0002] Nowadays, the commonly used carpets are mostly wool or chemical fiber carpets, and these carpets have the disadvantages of being easy to pollute, not easy to clean, easy to generate static electricity when dry, and easy to be moth-eaten when wet.
However, the existing composite carpets often use adhesives to bond the surface layer and the bottom material, which is prone to produce harmful substances to the human body, and does not conform to the current trend of green environmental protection.

Abstract

The invention relates to an environmentally-friendly polyurethane composition for making a carpet backing material, and its preparation method, and belongs to the technical field of foam foaming. The composition is prepared through using a component A and a component B, wherein the component A is composed of 40-80wt% of polyether polyol A, 0-40wt% of polyether polyol B, 0.2-2.0wt% of a foam stabilizing agent, 0.2-2.0wt% of a catalyst and 10-50wt% of a solid filler. The blow-in of air through a bubbling machine substitutes a physical or chemical foaming agent in the preparation method of the composition, and belongs to an environmentally-friendly material. The temperature-sensitive catalyst used in the component A has small influences on the early-stage system reaction rate and the fluidity, is benefit for the continuous lying production in the product preparation, and guarantees the excellent performances of the composition; and the composition is a polyurethane carpet backing material having the advantages of high bonding property, no smell, and environmental protection, and the bonding strength of the solidified composition is very good.

Description

technical field [0001] The invention relates to an environment-friendly polyurethane composition for making carpet backing material and a preparation method thereof, belonging to the technical field of foaming. Background technique [0002] Nowadays, the commonly used carpets are mostly wool or chemical fiber carpets, and these carpets have the disadvantages of being easy to pollute, not easy to clean, easy to generate static electricity when dry, and easy to be eaten by insects when wet. However, the existing composite carpets mostly use adhesives to bond the surface layer and the bottom material, which is easy to produce harmful substances to the human body, and does not meet the current general trend of green environmental protection. Contents of the invention [0003] According to the deficiencies of the prior art, the technical problem to be solved by the present invention is: provide an environment-friendly polyurethane composition for making carpet backing material,...
