Abstract
The invention discloses an extrusion method for a faux wood sheet material, comprising the following steps that: (1) a raw material of the sheet material, a colored species of background color, and a colored species of wood grains are taken and fully mixed to obtain a mixture, wherein, the colored species of wood grains comprises a carrier material and pigments, the melting point of the colored species of wood grains is 10-50 DEG C higher than the melting point of the raw material of the sheet material, and the melt index of the carrier material in the colored species of wood grains is less than 5; and (2) the mixture is put in an extruder for extrusion, the extruded mixture is put into moulds and cooled to the room temperature to obtain the faux wood sheet material with irregular strips. The aux wood sheet material extruded by the invention has good wood-like effect.
Description
Technical field
The present invention relates to a kind of extrusion method of imitative wood-grain plate.
Background technology
At present, in the production of plastic extruding forming sheet material,, generally can adopt the effect that reaches imitative wood in the technology of plate surface printing lines in order to form the lines of natural wood at plate surface, this technology can form imitative wood grain road pattern at plate surface, yet has certain defective:
(1) lines can only be present in the surface of sheet material, as because of construction need add man-hour to plate surface, can damage the wood grain effect of product surface;
When (2) sheet material used out of doors, climatic factors such as temperature, humidity can make that plate surface is corroded, and destroyed the wood grain that the product surface printing is got on, and reduced the fidelity of product;
(3) lines that is printed on plate surface is subjected to the restriction of galley, causes the repeatability on imitative wood grain road big, lack randomness and change, so simulated effect is relatively poor, can not satisfy the demands of consumers.
Summary of the invention
The extrusion method that the purpose of this invention is to provide a kind of imitative wood-grain plate, the imitative wood effect of the imitative wood-grain plate of extruding is better.
The object of the present invention is achieved like this: a kind of extrusion method of imitative wood-grain plate may further comprise the steps:
(1) gets sheet material raw material, background color look kind, wood grain look kind respectively, obtain compound after mixing fully, wherein wood grain look kind is made up of carrier material and pigment, and the fusing point of wood grain look kind is higher 10～50 ℃ than sheet material raw material, and the melt index of carrier material is less than 5 in the wood grain look kind;
(2) compound is put into extruder and extrude, extrude the back typing and be cooled to room temperature, obtain having the imitative wood-grain plate of random stripe.
Principle of the present invention is as follows:
When extruding, the sheet material raw material begin fusion plastification, and the look kind also begins to melt painted, and wherein background color look kind is because its base-material and sheet material raw material mix, and fusing point unanimity and good fluidity can evenly disperse in the sheet material raw material, form uniform ground color; And wood grain look kind fusing point is than sheet material raw material height, and by mobile relatively poor poor (melt index is less than 5) of its carrier material, therefore when the fusion of sheet material raw material, wood grain look kind does not have complete fusion, but partial melting is in the fluid state of fritting, can not be melted in the sheet material raw material, then under the effect of pressure, the wood grain look kind of fritting is along with the sheet material raw material of fusion flow together, again after the typing cooling, form irregular wire striped, thereby reach imitative wood effect true to nature.
Preferably, the sheet material raw material are PS in the step of the present invention (1), and wherein PS preferably is made up of HIPS and GPPS.
Preferably, background color look kind is made up of PS and pigment in the step of the present invention (1); The carrier material of wood grain look kind be PC or PMMA or ASA or ABS or PS wherein one or more.
Therefore compared with prior art, the present invention has following beneficial effect:
(1) owing to wood grain look kind is mixed with sheet material raw material, background color look kind process fully, so the distribution of wood grain look kind is a completely random and random, fusion plastification through extruder, the various piece that wood grain look kind can be distributed to sheet material comprises inside, do not resemble and print the surface that only can appear at sheet material, even like this because processing such as need the sawing sheet material, cut of construction, planes, the inside of sheet material still has wood grain to exist;
(2) distribution of wood grain look kind in sheet material is fully random and at random among the present invention, therefore avoided the dullness of printing and repeated, thereby improved the fidelity and the naturalness of wood grain greatly;
(3) among the present invention the carrier material of wood grain look kind can select for use PC or PMMA or ASA or ABS or PS wherein one or more, can form different wood grains, as coarse groove, microgroove, circular whorl, mineral line or the like, can satisfy consumer's different demands.
