Abstract

The present invention relates to a polyurethane elastic floor brick and a manufacture method thereof, which belongs to decorative materials. The present invention overcomes the defects of the existing inorganic ceramic bricks, wood floors and plastic floors which have odors that the materials, the structures and the technologies are complicated, the elasticity of products are bad, and the structures are simple. A polyurethane elastic floor brick is formed by using 10 to 25 portions of 4, 4'-diphenylmethane diisocyanate, 0 to 15 portions of, 1, 4-butanediol, 75 to 90 portions of polypropylene oxide polyhydric alcohol, 20 to 50 portions talcum powder or Calcium carbonate, 5 to 10 portions of flame retardant agents of phosphate series which is treated by a series of processes such as heating, mixing, stirring, casting, remolding, etc. The polyurethane elastic floor brick has the advantages of deformation resistance, discoloring resistance, slide resistance, good elasticity, light weight, good performance, wear-resistance, impact resistance, easy transportation and easy installation.

Description

The polyurethane elastic floor board brick

Affiliated technical field

The present invention relates to a kind of polyurethane elastic floor board brick that belongs to ornament materials, and relate to its manufacture method.

Background technology

The inorganic tile that mostly be not only sliding but also hard, nonelastic on the domestic market, contains radioactive substance radium; Waterproof, fire line be poor, destroy the wood flooring of natural resource and the plastic floor of peculiar smell is arranged.Disclosed as Chinese patent 00111485.9 disclosed " a kind of floor of resisting against interference, radiation, fire and water " is the floor that constitutes top panel, bottom panel, thick china combination with materials such as metals such as steel, iron, aluminium, nonmetal, light flame-retardant foaming, and its raw material complexity, complex structure have caused technology product poor flexibility and structure loaded down with trivial details, that produced single.

Summary of the invention

The objective of the invention is at the deficiencies in the prior art, a kind of indeformable, nondiscolouring, anti-skidding, full of elasticity, light weight, excellent, wear-resistant, the anti-collision of performance, easily transportation, polyurethane elastic floor board brick easy for installation are provided, and provide also that it is easy and simple to handle, the flow process simple manufacturing method.

The objective of the invention is to be achieved through the following technical solutions.

A kind of polyurethane elastic floor board brick, it comprises following (by weight) composition:

4,4 '-methyl diphenylene diisocyanate 10-25 part 1,4-butanediol 0-15 part

PPOX polyalcohol 75-90 part French chalk or calcium carbonate 20-50 part

Phosphate fire-retardant agent 5-10 part

Its manufacture method is:

A, with 4,4 '-methyl diphenylene diisocyanate slowly adds in 40-80 ℃ the PPOX polyalcohol equably and stirs and form mixture, is smelt prepolymer under 80-90 ℃ of constant temperature in airtight 30 minutes-4 hours;

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.
