A kind of colour-fast wood-like sheet of high intensity
Technical field
The present invention relates to a kind of building and ornament materials, the particularly a kind of emulation of height, high intensity, non-fading wood-like sheet.
Background technology
, used as a kind of natural building and ornament materials, its use is almost synchronous with the development of human civilization, from tradition for timber
Build house, manufacture woodwork furniture, to wooden articles for use miscellaneous, and Wood craft etc., its occupation mode, make
The breakthrough for having obtained emerging in an endless stream with fineness, use range.
In the current age, with science and technology and economic high speed development with rapid changepl. never-ending changes and improvements, the use demand of timber even more increasingly increases,
Due to the growth cycle that continuous exploitation all the time and timber itself need, world forest resources in short trend, separately due to
With different degrees of coyoting and waste, the in short supply of timber resources is more exacerbated;Meanwhile, the forest reserves are the wealth of the mankind,
Its adjustment effect to natural environment more can not be ignored, and pursue the theme that environmental protection is the world today, therefore, how can use
On meet demand, and the valuable forest reserves can be protected, become the research topic of insider.
At present, " wood effect " product of various unlike materials is occurred in that on market to meet decoration demand, such as anticorrosive wood,
Modeling wood, wood composite etc., such product can reach design requirement from decorative effect, but material combination property is general, additionally, also going out
The excellent imitation wood material of existing comparison, the such as patent No. " 200710150629.4 ", a kind of entitled " formula of cement wood-like sheet
And preparation method " disclosed in technology, its formula is as follows:Prepare 1000 grams of materials, 300 grams of chicken girt hybrid particles, No. 500 silicic acid
100 grams of salt cement, 200 grams of building sand, 108 glue and water are suitably tuned into concrete-like, after the material mixture more than is uniform, use trowel
Knife is put on mould, thickness requirement 5-lO millimeters, then spreads the iron net of 0.5 centimetre of glass fiber net or eye distance, then pour into and more than
Material prescription is identical, simply Portland cement change into gram light yellow cement of light yellow portland cement, i.e., 200,200 grams build
Build sand, or Portland cement.The cement wood-like sheet can reach imitation wood effect, and physical strength aspect is also carried
Height, its weak point has:Also there is shortcoming in finished product overall construction intensity, texture and color emulator be not high, color fastness
Can not be good, and later maintenance is costly.
The content of the invention
The purpose of the present invention be for " wood effect " product physical strength in the market, emulator, usage cycles,
Weatherability is not good, and impact effect can not be lasting, and the high deficiency of maintenance cost, there is provided a kind of colour-fast wood-like sheet of high intensity,
The silicon rubber that it is strong using replication capacity, alkaline resistance properties is good, tensile strength is high does mould material, by integrally formed cement-based material system
Make, the wood-like sheet physical strength and usage cycles are greatly improved, and finished product will not be layered, peel off, while good weatherability,
Emulator is high, and more resistant, color is more durable, and safeguards simple.
To solve above-mentioned prior art problem, the technical scheme is that:
A kind of colour-fast wood-like sheet of high intensity of the present invention includes surface coloring layer and structure filling layer, the surface coloring
Layer adopts high performance filled concrete using the modified mill base of cement-based polymers, the structure filling layer;
The modified mill base of the cement-based polymers is obtained using following components:
The weight portion of cement 45~65,
The weight portion of hard calcium carbonate 8~30,
The weight portion of iron oxide pigment 2~20,
The weight portion of acrylic emulsion 10~30,
The weight portion of water 10~35;
Preferably, the best composition scheme of the modified mill base of the cement-based polymers is:
No. 425 weight portions of cement 55,
The hard weight portion of calcium 10,
The weight portion of iron oxide pigment 8,
The weight portion of acrylic emulsion 15,
The weight portion of water 12;
The high performance filled concrete is obtained using following components:
The weight portion of cement 15~35,
The weight portion of river sand 15~35,
The weight portion of rubble 35~65,
The weight portion of high efficiency water reducing agent 0.3~1,
The weight portion of cellulose 0.2%~1,
The weight portion of iron oxide pigment 0.1%~8.
Preferably, the best composition scheme of the high performance filled concrete is:
The weight portion of cement 24,
The weight portion of river sand 24,
The weight portion of rubble 48,
The weight portion of high efficiency water reducing agent 1,
The weight portion of cellulose 0.9,
The weight portion of iron oxide pigment 2.1.
The macome-scale is 5~10mm, and the river sand particle diameter is 10~280 mesh.
A kind of colour-fast wood-like sheet of high intensity of the present invention, its advantage has:
1st, with the characteristic of cement, while wood decoration effect is kept, wood using life is overcome short, outdoor resistance to
The shortcomings of time property difference and not long durability, the use range of wood decoration product is widened, design space is big;
2nd, finished product long service life, safeguards simple, and relative to like product, cost obtains very big saving;
3rd, the wood-like sheet structure sheaf adopts high performance filled concrete, and finished product structure intensity is big, and superficial layer adopts cement
Based polyalcohol is modified mill base, and emulator is high, and by integral forming mode finished product, material bond strength is big, finished product
Will not be layered, peel off, and good weatherability.
