Problems solved by technology

But for the similar products sold on the market at present, the hardness (surface hardness) and strength of the products are not ideal, and they are easy to be deformed and damaged during transportation and use, especially the products produced have poor plasticity. It cannot be cut at will, which limits the scope of this material to produce various irregular shaped decorations

Embodiment 1

[0013] A component, its proportioning ratio is:

[0014] Polypropylene alcohol 10kg Triethanolamine 0.15kg

[0015] Silicone oil 0.2kg Fluorotrichloromethane 0.3kg

[0016] Distilled water 0.03kg Melamine resin 0.09kg

[0017] Acrylate copolymer 0.5kg Tris(2.3-dichloropropyl) phosphate 0.4kg Component B: diphenylmethane diisocyanate 11.67kg

[0018] Stir component A for 20 minutes at constant temperature (20°C to 30°C), then add component B and shake well, then pour it into the pre-made film and compress it with a compressor.

Abstract

A wood-like polyurethane contains polypropanediol, triethanolamine, silica oil, fluotrichloromethane, water, tripolychloramine resin, acrylate copolymer, tri (2,3-bichloropropyl) phosphate, and diphenyl methane diisocyanate. Its advantages include high hardness, vein and colour similar to those of wood, moisture-proofing nature, fire resistance, not decolouring, and low cost.

Description

technical field [0001] The invention relates to a polyurethane rigid foam material, in particular to a wood carving type polyurethane imitation wood technology. Background technique [0002] my country is a country that is poor in timber, and the country has already implemented the policy of ordering to stop logging and protect forest resources. Therefore, the prospect of using new technologies and new materials to replace log products is very optimistic. But for the similar products sold on the market at present, the hardness (surface hardness) and strength of the product are not ideal, and it is easy to be deformed and damaged during transportation and use, especially the produced product has poor plasticity. It cannot be cut at will, which limits the scope of this material to produce various irregular shapes. Contents of the invention [0003] The object of the present invention is to provide a kind of polyurethane imitation wood with low cost that can replace wood an...
