Abstract
The invention is layered symmetric structure, the center of which is a center layer (1), forming layer (2), strengthening layer (3), waterproof layer (4) and wear-resistant layer (5) are respectively distributed symmetric above and under the center of the structure (1) , the modified magnesite and composite materials have conspicuous advantages: (1) good mechanical properties, and high compressive resistance, high flexural strength, not easy to deform, which is conducive to enhancing life; (2) waterproof performance is particularly conspicuous. Blisters are not afraid of flooding, improving the utilization rate of repeat; (3) It increases the ability of wear-resisting, the surface can be maintained for a long time in the formation and thus concrete structures on the surface cleanliness; (4) It is easy to grip nails, small density, light weight, easy to construction; (5) It is formaldehyde-free, non-radioactive, environmental safety; (6) and it has a wide range of uses, in addition to concrete formwork for the construction, production of building blocks can be used, as other pad, parapet panels, decorative plates, etc.
Description
Technical field
The present invention relates to a kind of composite artificial sheet material, be widely used in building concrete template, building block production supporting plate, other backing plate, guardrail board, decorative panel etc.
Background technology
The very big construction material of consumption when 1, cast in place concrete form is the concrete component making, according to statistics, every 1m
3Building concrete member (post, beam, plate etc.) template consumption is up to 4～5m
2, its expense accounts for 30～35% of concrete component cost.Traditional template plank, over past ten years, multiselect bamboo plywood, steel plate.They respectively have characteristics: plank easily installs, light, but shortage of resources, the easy dilatancy that absorbs water, recycling rate of waterused is low, and component surface is of poor quality; The anti-folding of bamboo plywood, impact resistance, but it is yielding to absorb water; Steel form is durable, and component surface is smooth, but weight is big, and it is yielding easily to get rusty, drop the back, construction and installation inconvenience.If can go out a kind of novel template with a kind of new manufacture of materials, have the advantage of timber shuttering, bamboo offset plate mould, steel mould and overcome their some deficiency, will be a big creative contribution that promotes that template already develops.
2, magnesite composite is to be adhesive with magnesia (claiming magnesium oxychloride again), magnesium chloride, adds a kind of new material of multiple filler, muscle material curing molding again.Though China's magnesite product production has only the history in more than 20 year, develop very fast.Particularly after the relevant standard laid down by the ministries or commissions of the Central Government and " the packaged design specifications of magnesium oxychloride concrete " issue, new product is batchs of introduces to the market.Because this material has some premium properties of timber, cement even steel, its application is very extensive, and great potential remains to be developed.
The material of main part of magnesite composite is magnesia, magnesium chloride, and a series of hydrolysis, physical and chemical processes such as aquation, sclerosis take place in the use.

But magnesite product compare with the Portland cement goods have light specific gravity, the characteristics of good springiness secondary operations, but the deficiency of the moisture absorption, general " frost " is arranged also.If can produce than wooden model, bamboo offset plate mould, the more excellent multifunction formboard of steel mould performance with magnesite material, must be subjected to the common concern and the favorable comment of scientific and technological circle, engineering circle, it is the innovation greatly that magnesite material is used, not only can promote exploitation, the application of magnesite composite article, can also promote the development of template industry.
Summary of the invention
The present invention is intended to release a kind of new construction of magnesite composite board material, new prescription, is used to make template, produces the new type formwork that welcome in high-quality extremely market.
Its technical scheme is:
This plate is the stratiform symmetrical structure, its center is the division center layer, on the division center layer, under the shape layer that is symmetrically distributed respectively, enhancement Layer, composition of raw materials by this layer weight in the division center layer has magnesia 17～22%, magnesium chloride 8～12%, flyash 18～22%, sawdust or tangerine bar bits 25～35%, water 10～15%, auxiliary agent 0.5～1%, resin 2～4%, the shape layer material is a fiberglass gridding cloth, enhancement Layer has magnesia 28～35% by the composition of raw materials of this layer weight, magnesium chloride 15～25%, Paris white 20～25%, water 15～20%, auxiliary agent 0.5～1%, resin 2～4%.
In addition: on the enhancement Layer, under also be symmetrically distributed respectively waterproofing course, antifriction layer; Also have waterproof agent in the composition of raw materials of division center layer, account for 2～3% of this layer weight by weight; Waterproof agent is also arranged in the enhancement Layer composition of raw materials, account for 2～3% of this layer weight by weight; Waterproofing course is a resin bed; The antifriction layer is a glass fiber reinforced plastics; Division center layer, shape layer, enhancement Layer, waterproofing course, antifriction interlayer are bonding under pressure compound.
The length that the multifunction formboard that the present invention releases is raised magnesite composite, keep away its weak point, be equipped with the raw material of multiple modification, select the stratiform symmetrical structure, bonding under pressure compound back maintenance by modification and compound, makes the advantage mutual superposition of homogenous material, give full play to, their shortcoming is overcome and avoid, thereby it is reasonable to form material-structure, the board of function admirable, have outstanding characteristics: (1) is because the division center layer is the thick-layer shape, and sawdust wherein or the collocation of tangerine bar bits grain thickness, thereby mechanical property is good, resistance to compression, the rupture strength height, not yielding, favourable raising application life; (2) owing to be equipped with waterproof agent in the prescription of division center layer, enhancement Layer, and the compound sticking waterproofing course, except that fire prevention, anti-aging is, water resistance is particularly outstanding, is not afraid of the water logging bubble, the repeat usage raising; (3) owing to the compound antifriction layer in top layer, wear resistance improves, and can keep the smooth of surface for a long time, thereby surface of concrete structure is clean and tidy; (4) hold that nail property is good, density is little, in light weight, be easy to construction; (5) formaldehydeless, "dead", Environmental Safety; (6) of many uses, except that as the building concrete template, also can make building block production supporting plate, other backing plate, protective rail plate, decorative panel or the like.
