Cement fiber melamine veneering plate and preparation method thereof
Technical field
The present invention relates to a kind of cement fiber melamine veneering plate and preparation method thereof.
Background technology
Ornament materials is extremely many by various description of materials in recent years, as density board, glass magnesium plate etc., but its fire prevention, Moisture-proof environment-friendlyshoe require do not reach.For another example granite, marble, ceramic tile etc., but have that price is high, a Heavy Weight, easily surface scratches, cracking, and the defects such as trouble are installed.
Prior art, also has and adopts thick china to come alternative granite, marble, ceramic tile etc., on substrate, namely paste layer of surface film form a kind of composite plate.But mostly the skin covering of the surface of this panel is the mode adopting cold subsides, and namely mainly bond by white glue with vinyl, and white glue with vinyl contains a certain amount of formaldehyde, thus damage human body, environmental protection is not up to standard.And, adopt cold subsides of white glue with vinyl to bond, the phenomenon such as also easily occur skin covering of the surface bleed in wet condition, come unstuck, have a strong impact on the service property (quality) of thick china.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, provide that a kind of cost is low, fire prevention, moisture effect is good, easy for installation, and not easily surface scratches, not easy to crack, also can not bleed, the cement fiber melamine veneering plate that not easily comes unstuck during wet weather.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of cement fiber melamine veneering plate, this thick china comprises Cement fibre substrate (cement fibrolite plate), described Cement fibre substrate also bonds one deck melamine impregnated paper wainscot layer.
As preferably, the thickness of described Cement fibre substrate is 5 ~ 7mm.Adopt above-mentioned thickness, effectively control the weight of substrate, do not affect again the overall performance of substrate simultaneously.
As preferably, the thickness of described melamine impregnated paper wainscot layer is 1.5 ~ 2.5mm.Adopt the melamine impregnated paper wainscot layer of above-mentioned thickness, the panel of preparation not easily come unstuck, bleed, wear life is long.
The present invention also provides a kind of preparation method of above-mentioned cement fiber melamine veneering plate, and concrete technical scheme is:
(1) get cement fibre base plate, sanding surface is smooth;
(2) by the Cement fibre substrate after the smooth process of step (1) sanding surface, surface is through high temperature hot pressing one deck melamine impregnated paper wainscot; Hot pressing pressure 1000 ~ 1200 tons, hot pressing time is 45 ~ 50 seconds, and hot pressing temperature is 170 DEG C ~ 190 DEG C.
Cement fibre substrate of the present invention and melamine impregnated paper wainscot are commercially available prod.
Advantage of the present invention and beneficial effect:
1. cement fiber melamine veneering plate of the present invention, surface adopts melamine impregnated paper wainscot layer, it has the advantages such as environmental protection, high temperature resistant, anti scuffing, with substrate compound use, thus cost is low, fire prevention, moisture effect is good to make the panel prepared have, easy for installation, and surface not easily scratch, not easy to crack, also can not bleed, the advantage of not easily coming unstuck during wet weather.
2. cement fiber melamine veneering plate of the present invention, quality is light, install change convenient, can extensively hair in hospital, public place of entertainment, hotel, the various fire-proof and damp-proof wall decoration in washroom.
3. cement fiber melamine veneering plate of the present invention, employing be heat pressing process make; Melamine in melamine impregnated paper wainscot layer is (170 DEG C ~ 190 DEG C) at high temperature, play the effect of adhesive glue, melamine impregnated paper wainscot layer and Cement fibre substrates into intimate are fitted, thus the panel prepared not bleed, do not come unstuck, wear life is long.
Accompanying drawing explanation
Accompanying drawing is the structural representation of melamine faced chipboard of the present invention.
As shown in the figure: 1. Cement fibre substrate, 2. melamine impregnated paper wainscot layer.
Detailed description of the invention
Below by embodiment, the present invention is described in further detail, but the present invention is not only confined to following examples.
As shown in drawings, cement fiber melamine veneering plate of the present invention, comprises Cement fibre substrate 1, described Cement fibre substrate 1 also bonds one deck melamine impregnated paper wainscot layer 2.
The thickness of Cement fibre substrate 1 is 5 ~ 7mm, and the thickness of melamine impregnated paper wainscot layer is 1.5 ~ 2.5mm, prepares the dimension board of length × wide=1.22 meter × 2.44 meters.
Embodiment 1
The preparation technology of cement fiber melamine veneering plate of the present invention is: (1) gets cement fibre base plate, sanding surface smooth (the conventional sanding treatment process of industry); (2) by the Cement fibre substrate after the smooth process of step (1) sanding surface, surface is through high temperature hot pressing one deck melamine impregnated paper wainscot; Hot pressing pressure 1200 tons, hot pressing time is 50 seconds, and hot pressing temperature is 170 DEG C.
Embodiment 2
The preparation technology of cement fiber melamine veneering plate of the present invention is: (1) gets cement fibre base plate, and sanding surface is smooth; (2) by the Cement fibre substrate after the smooth process of step (1) sanding surface, surface is through high temperature hot pressing one deck melamine impregnated paper wainscot; Hot pressing pressure 1000 tons, hot pressing time is 50 seconds, and hot pressing temperature is 175 DEG C.
Sample prepared by the present invention is detected, specification according to JC/T564-2000 " fiber reinforced calcium silicate board ", GB6566-2001 " radioactive material radionuclides limitation ": 1.22 meters × 2.44 meters × 6mm.Detect each sample and all meet JC/T564-2000 " fiber reinforced calcium silicate board ", GB6566-2001 " radioactive material radionuclides limitation " requirement.
Testing result is shown in Table 1:
Table 1 embodiment of the present invention each sample performance test results
As can be known from the above table, cement fiber melamine veneering plate of the present invention, meet the requirement of constructional materials relevant criterion completely, and some performance is better than standard-required.
