Abstract
The present invention relates to polyurethane imitation wood which comprises polypropylene glycol, triethanolmine, silicon oil, trichlorofluoromethane, water, trimeric chloramine resin, acrylate copolymer, tributyle phosphate (2, 3-dichloropropyl), diphenylmethane diisocyanate. The present invention has broad application area; taking imitation wood products as examples, the wood grain, the colors and the hardness of produced products all achieve the requirements for the quality of solid wood products; moreover, compared with wood products, the imitation wood products has the advantages of moisture resistance, water resistance, fire retardance, fastness, no wrinkling, etc. The products manufactured by the present invention can be cut at will, and the vivid degree is high; the cost of the products is far lower than that of similar wood products.
Description
Technical field
The present invention relates to a kind of hard polyurethane foam material, particularly relate to a kind of Wood-carving type imitation polyurethane wood technology.
Background technology
China belongs to the country of a timber poorness, and country's imperative instruction already stops to cut down timber, the policy that protects forest resources.So the prospect of utilizing new technology, novel material to substitute former woodwork technology is very optimistic.But at present, the like product of being sold on the market, the hardness of product (surface hardness) is all very undesirable with intensity, easy deformation and damage in transportation and use, especially the product plasticity-of being produced is relatively poor, can not arbitrarily cut, this point has limited the scope of the various irregular moulding ornaments of this kind material produce.
Summary of the invention
The purpose of this invention is to provide a kind of can replacing wood, carry out cutting operation, Wood-imitation polyurethane with low cost.The objective of the invention is to realize in the following manner: include component A and B component, wherein component A includes poly-third ethanol, trolamine, silicone oil, fluoro trichloromethane, water, Melamine resin sheet, acrylate copolymer, tricresyl phosphate (2.3-two chloropropyls) ester, B component is a diphenylmethanediisocyanate
Component A: % counts by weight, and its proportioning is:
Poly-third ethanol, 85.3～85.8% trolamines 1.2～1.4%
Silicone oil 1.5～1.7% fluoro trichloromethane 2.5～2.7%
Water 0.2～0.3% Melamine resin sheet 0.7～0.9%
Acrylate copolymer 4.2～4.4%
Tricresyl phosphate (2.3-two chloropropyls) ester 3.3～3.5%
B component: % counts by weight, and its proportioning is:
Diphenylmethanediisocyanate A: B=0.8 5～1.65
Component A (20 ℃～30 ℃) under temperature constant state was stirred 20 minutes, add B component then, shake up, pour into then in the set mould, form with compressor compresses again.
Application Areas of the present invention is wide, imitative wooden series products is an example, lines, color, the hardness of the product of producing all reaches the specification of quality of wood products, and compare with woodwork, moistureproof, be not afraid of superiority such as bubble, fire-resistant, colour-fast, non-scale, the product that manufacturing of the present invention is come out can cut randomly, the naturalness height, and its cost is well below similar Wood products.
Embodiment
The invention will be further described below in conjunction with embodiment:
Embodiment 1:
Component A, its proportioning is:
The poly-third ethanol 10kg trolamine 0.15kg
Silicone oil 0.2kg fluoro trichloromethane 0.3kg
Distilled water 0.03kg Melamine resin sheet 0.09kg
Acrylate copolymer 0.5kg tricresyl phosphate (2.3-two chloropropyls) ester 0.4kg
B component: diphenylmethanediisocyanate 11.67kg
Component A (20 ℃～30 ℃) under temperature constant state was stirred 20 minutes, add B component then and shake up, pour into then in the set mould, form with compressor compresses again.
