Plant type soft polyurethane foam for radiation protection seamless wallpaper, and preparation method thereof

Abstract

The invention discloses a plant type soft polyurethane foam for radiation protection seamless wallpaper. The plant type soft polyurethane foam is prepared from, by weight, 0.07-0.08 parts of triethylamine, 0.2-0.26 parts of dibutyltin dilaurate, 0.28-0.34 parts of water, 56-58 parts of 2,4-toluene diisocyanate, 0.9-1.1 parts of an organosilicon foam stabilizer, 85-87 parts of polyethylene glycol 400, 9.5-10 parts of glycerin, 18-20 parts of corn straws, 1.2-1.5 parts of methyl vinyl trifluoropropyl silicone rubber, 1.2-1.5 parts of nanometer tourmalinite powder, 0.4-0.6 parts of nanometer ferriferrous oxide, 0.9-1.1 parts of nanometer alumina, a proper amount of a 0.2% sodium hydroxide solution, 9-10 parts of waste tire rubber powder and 3-3.2 parts of concentrated sulfuric acid. The polyurethane foam has the advantages of good flame resistance, absorption of harmful electromagnetic waves, negative ion emission, human body health benefiting, and no reduction of the elasticity.

Description

technical field [0001] The invention relates to the technical field of polyurethane foam preparation, in particular to a plant-type soft polyurethane foam for radiation-proof seamless wallpaper and a preparation method thereof. Background technique [0002] The invention relates to the technical field of polyurethane foam preparation, in particular to a plant-type soft polyurethane foam for anti-ultraviolet seamless wallpaper and a preparation method thereof. Background technique [0003] Polyurethane foam is one of the commonly used cushioning materials in the packaging industry. Like most polymer materials, it faces challenges in terms of resources and the environment. Generally, plants contain chemical substances such as cellulose, hemicellulose, and lignin. The use of these environmentally friendly biological materials with natural degradability has become one of the important aspects of environmental protection and sustainable development strategies in countries all o...

Problems solved by technology

Soft-covered wallpaper has the characteristics of good three-dimensional feel. Polyurethane foam is often used. If the above-mentioned foam is used for wallpaper, the tensile strength, durability, heat resistance, water resistance, cleanability, and shock resistance of the foam will be improved. , heat insulation, sound insulation and other properties can not meet the needs, need to be improved
