CN2228841Y - Fire-proof and water-proof composite Baoli board - Google Patents

Abstract

The utility model provides a fire-proof and water-proof composite Baoli board, comprising a face layer and a bottom board. The utility model is characterized in that the structure of an intermediate layer is three layers of materials, that is to say, a layer of composite material is arranged between two layers of fire-proof cloths, and the surface layer, the intermediate layer and the bottom plate are successively spread flatly, glued together and solidified into integration. The utility model can replace wooden clamping plates, which has the advantages of fire resistance, water resistance, no poison, acid-alkali resistance, light weight, low cost, high strength, high toughness, etc. The utility model can be widely used for the indoor and outdoor decoration, the construction materials and the manufacture of furniture.

Description

The compound layered board of a kind of fire-proof and water-proof

The utility model relates to a kind of multilayer composite board of being made by chemical materials, particularly a kind of compound layered board of fire-proof and water-proof that is applicable to indoor and outdoor decoration and building materials field.

At present, owing to developing rapidly of building industry and decorative craft, wooden splint particularly paper overlaid plywood, layered board etc. is in very great demand on ornament materials market, but wooden splint is subjected to the restriction of timber resources, more and more can not satisfy the demand in market, and price rises constantly.The disadvantage of wooden splint is met fire burns exactly, easily breaking out of fire.Many in recent years R﹠D institutions and scientific worker adopt non-wooden composite board material as aspect the substitute of wooden splint just in active research.Existing compound layered board generally is made up of three-decker at least, i.e. surface layer, intermediate layer and base plate, the intermediate layer is to adopt one deck chemical fabric to make skeleton, and surface layer and base plate adopt composite, the compound layered board of this three-decker, its shortcoming is that intensity is low, poor toughness, fracture easily is in order to improve intensity, must increase thickness, make composite plate not only thick but also heavy, be difficult for transportation and construction, can not guarantee fire prevention and waterproof at prescription and process aspect in addition.

For overcoming the shortcoming of prior art, task of the present utility model is to provide the new compound layered board of a kind of intensity height, good toughness, lightweight, energy fire-proof and water-proof.

Task of the present utility model realizes that as follows accompanying drawing has provided specific embodiment.With reference to accompanying drawing, the utility model comprises surface layer 1 and base plate 3, the structure that it is characterized in that intermediate layer 2 is a trilaminate material, it is two-layer fire prevention cloth clamp one deck composite, above-mentioned flameproof fabric adopts glass fabric, and above-mentioned composite is to be formed by modifier and magnesium chloride, magnesium oxide solution and an amount of urea-formaldehyde glue, talcum powder, lithopone, sawdust, pigment mixed preparing that oxalic acid, hydrochloric acid are prepared.

The utlity model has following characteristics, the one, because the three-decker of double-deck skeleton is adopted in the intermediate layer, can reduce by every layer thickness during production, make weight saving, and intensity and toughness are much improved.The 2nd, material selection, preparation and structural manufacturing process can guarantee fire protection flame retarding, and be high temperature resistant, and acid and alkali-resistance is waterproof and dampproof, and is nontoxic.The 3rd, can according to, can follow closely, can glue, can spray, construction application is convenient.The 4th, surface layer 1 is smooth and bright like a mirror, must not paste stencil paper and can print multicolour and multiple decorative pattern, wood grain, bag etc.The 5th, cost is low, manufacture easily, market prospects are wide, are widely used in indoor and outdoor decoration, construction and the various furniture of making etc., being specially adapted to places such as dangerous goods store, oil depot, gas station, chemical plant, is the ideal product that replaces wooden splint and plasterboard.

Accompanying drawing is a cutaway view of the present utility model.

Describe in detail below in conjunction with accompanying drawing.

To be prepared in advance in proportion by the additive that bakelite powder, alum, honey are formed, add in major ingredient magnesium chloride and the magnesium oxide solution, add an amount of acrylic emulsion, cement, lime, sawdust, pigment again, the composite material of back as surface layer 1 stirs.

To prepare in advance in proportion by the modifier that oxalic acid, hydrochloric acid are formed, add in major ingredient magnesium chloride and the magnesium oxide solution, add an amount of urea-formaldehyde glue, talcum powder, lithopone, sawdust, pigment again, the back that stirs is as the composite in intermediate layer 2 and the compound bed material of base plate 3.

Smooth smooth for guaranteeing surface layer 1, adopt glass mold, specification is changeable.Earlier mould cleaned, dry, waxing, during the wounded in the battle line of surface layer 1, should earlier decorative pattern be produced if desired.

Earlier from surface layer 1, successively surface layer 1, intermediate layer 2, base plate 3 are paved bondingly during making, on base plate 3, placed a plastic sheeting at last, get final product with the instrument strickling.Making finishes, and must treat on mould 6～8 hours, and making it to be solidified as after the one could the demoulding, takes off and places 3～5 days, can use after the air dry.

The utility model can also can adopt mechanization production with making by hand.

Claims (2)
