B, 1,4-butanediol are heated to 80-110 ℃ of constant temperature, and the prepolymer among the heating A mixes stirring rapidly with both after 80-110 ℃, add agent of phosphate fire-retardant and French chalk or calcium carbonate subsequently and mix;
C, the mixture that the B step is stirred pour in the mould of different size, difformity, different concaveconvex structures, toast, and back to be formed cooling and demolding gets final product.
Tricresyl phosphate (β-chloroethyl) ester, tricresyl phosphate (β-chloropropyl) ester, tricresyl phosphate (2,3-two chloropropyls) ester or methyl-phosphoric acid dimethyl ester are selected in the agent of phosphate fire-retardant for use.
Tricresyl phosphate (β-chloroethyl) ester is selected in the agent of phosphate fire-retardant for use.
The PPOX polyalcohol is selected the PPOX dihydroxylic alcohols for use.
With 4 of A step, 4 '-when methyl diphenylene diisocyanate slowly adds in 40-80 ℃ the PPOX polyalcohol equably and add the polyurethane pigment of different color simultaneously, stir to form mixture, under 80-90 ℃ of constant temperature, be smelt prepolymer in airtight 30 minutes-4 hours.
Earlier pattern transferring is layered in the mould of different size, difformity, different concaveconvex structures when carrying out the C step, the mixture that stirs in the B step is poured in it again, toast, back to be formed cooling and demolding gets final product.
The wood floor bolck of cooling and demolding is smeared the surface with the prepolymer of A step form bright layer.
Beneficial effect
Go on foot the polyurethane elastomer of poly-reaction generation as the main raw material(s) of wood floor bolck by AB, because of its good springiness that has, the good advantage of good, the various mechanical strength of rerum natura, make wood floor bolck have high strength, full of elasticity simultaneously, shock-resistant, wear-resistant, do tear, anti-deflect, free from extraneous odour, density are little, the characteristics of insulation; Fire retardant is an analog assistant that improves flammable polymer flame retardancy, novel phosphorus flame retardant belongs to additive flame retardant, additive flame retardant has characteristics such as applied range, easy to use, economical and practical, good flame retardation effect, has reduced cost when playing well anti-fire action; As filler, reduced cost by French chalk or calcium carbonate; The conversion of mould size, shape, concaveconvex structure can form different size, shape, rough structure, reaches different results of use, can play effects such as anti-skidding, attractive in appearance, massage; Polyurethane pigment by different color forms the wood floor bolck of different color, brings the wood floor bolck of different pattern to bring effect as the beyond thought art by the technology of transfer printing, has satisfied the demand of different people; Adopt industrial chemicals to protect non-renewable natural resource, protected ecology, protected environment.
