Problems solved by technology

As disclosed in Chinese Patent No. 00111485.9, "An Interference-proof, Radiation-proof, Fire-proof and Waterproof Floor" discloses that materials such as steel, iron, aluminum and other metals, non-metals, and lightweight flame-retardant foaming materials are used to form the upper panel, the bottom panel, and the veneer panel. The combined floor has complex raw materials and complex structure, resulting in cumbersome process, poor elasticity and single structure of the produced product.

Embodiment 1

[0019] A. Slowly and uniformly add 15kg of 4,4'-diphenylmethane diisocyanate into 85Kg polyoxypropylene diol at 60°C and stir to form a mixture, which is sealed at a constant temperature of 90°C for 1 hour to form a prepolymer thing;

[0020] B, 3kg of 1,4-butanediol is heated to a constant temperature of 90°C, after heating the prepolymer in A to 90°C, the two are mixed and stirred rapidly, and then 5kg of tris(β-chloroethyl)phosphate, Talcum powder 20kg stirring and mixing;

[0021] C. Pour the uniformly stirred mixture in step B into a 400mm×500mm, rectangular mold with a uniform columnar concave-convex structure, bake, and cool and demould after forming.

Embodiment 2

[0023] A. Slowly and uniformly add 25kg of 4,4'-diphenylmethane diisocyanate into 75kg of polyoxypropylene triol at 40°C and at the same time add blue polyurethane pigment to stir to form a mixture, and seal it at a constant temperature of 80°C Refined into prepolymer in 4 hours;

[0024] B, after heating the prepolymer in A to 80 DEG C, the calcium carbonate of tris (beta-chloropropyl) phosphate of 8kg and 50kg is mixed and stirred rapidly;

[0025] C. Pour the uniformly stirred mixture in step B into a 1000mm×1000mm, square mold with a flat bottom surface structure, bake, and cool and demould after forming.

Embodiment 3

[0027] A. Slowly and evenly add 10kg of 4,4'-diphenylmethane diisocyanate into 80°C, 90kg of polyoxypropylene triol and stir to form a mixture, and seal it at a constant temperature of 100°C for half an hour to form a prepolymer ;

[0028] B. Heat 15kg of 1,4-butanediol to a constant temperature of 110°C, heat the prepolymer in A to 110°C and mix and stir, then add 10kg of tris(2,3-dichloropropyl) phosphate and 30kg of talcum powder Quickly mix and stir;

[0029] C. First spread the transfer pattern in a 400mm×400mm, diamond-shaped, uniform dot-shaped concave-convex mold, and then pour the evenly stirred mixture in step B into it, bake it, and cool and demould after it is formed. .

Abstract

The present invention relates to a polyurethane elastic floor brick belonging to decorative material. It is made up by using (by weight portion) 10-25 portions of 4,4'-methylene diphenyl diisocyanate, 0-15 portions of 1,4-butylene-glycol, 75-90 portions of polyoxypropylene polyalcohol, 20-50 portions of talcum powder or calcium carbonate and 5-10 portions of phosphate series flame resisting agent through the processes of heating, mixing, stirring, pouring and demoulding. Said invented polyurethane elastic floor brick is non-deformable, non-decolourant, has rich elasticity and light weight, and is convenient for construction, etc.

Description

Technical field [0001] The invention relates to a polyurethane elastic floor tile belonging to a decorative material, and also relates to a manufacturing method thereof. Background technique [0002] In the domestic market, there are mostly inorganic tiles that are slippery, hard, inelastic, and containing radioactive radium; wooden floors with poor waterproof and fire resistance, damage to natural resources, and plastic floors with peculiar smell. As disclosed in Chinese Patent No. 00111485.9, "An Interference-proof, Radiation-proof, Fireproof and Waterproof Floor" discloses that materials such as steel, iron, aluminum and other metals, non-metals, and lightweight flame-retardant foams are used to form the upper panel, the bottom panel, and the veneer panel. The combined floor has complex raw materials and complex structure, resulting in cumbersome process, poor elasticity and single structure of the produced product. Contents of the invention [0003] The purpose of the...
