Abstract

The invention discloses environment-friendly polyurethane flexible foams. The polyurethane flexible foams in the formula comprise the following ingredients in parts by weight: 80-90 parts of polyether polyol, 10-20 parts of ricinus oil, 4-5 parts of water, 0.20-0.30 part of an amines catalyst, 0.10-0.20 part of an organic tin catalyst, 0.5-0.2 part of an alkaline metal catalyst, 0.5-1.5 parts of silicone oil 2370 and 52-56 parts of isocyanate. The invention further discloses a preparation method thereof. By adopting a one-step method to produce the green environment-friendly polyurethane flexible foams, the production technology and steps for raw material treatment are simplified, wherein the addition amount of ricinus oil reaches to 15-20%; natural resources are made full use of, 10-20% of the usage amount of polyether polyol can be reduced, and the harmonious development between human and nature is realized.

Description

technical field [0001] The invention belongs to a polyurethane soft foam product, and in particular relates to an environment-friendly polyurethane soft foam and a preparation method thereof. Background technique [0002] The main raw materials of polyurethane products are polyether polyols and isocyanates, both of which come from petroleum products. Since petroleum is a non-renewable resource, with the development of the global economy, energy consumption is increasing. Excessive reliance on oil resources is not conducive to environmental protection and energy conservation, nor is it conducive to the stability and long-term development of the country and enterprises strategically. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly flexible polyurethane foam and a preparation method thereof, so as to overcome the above-mentioned shortcomings and deficiencies. [0004] Through experimental research and development,...
