Abstract

A light heat-insulating cement wall panel is characterized by comprising the following raw materials in percentage by weight: 20 to 30 percent of high alumina cement, 20 to 30 percent of ceramic aggregates, 20 to 30 percent of fly ash, 20 to 30 percent of straw fibers or wood fibers, 20 to 30 percent of perhydro foaming agent and 20 to 30 percent of rubber latex cement modifier. The ceramic aggregates are added into the cement as a light aggregate of the cement; steel nets are added in the wall panel; and meanwhile, the straw fibers or wood fibers are added. Therefore, high compressive strength and high bending strength of the wall panel are guaranteed; the wall panel has advantages of light weight, good heat insulation, and much higher indexes than the prior cement IRC board, chlorine-magnesium containing cement light board and plaster light body partition wall board.

Description

Light heat-insulating cement wall panel

Technical field

The present invention relates to a kind of building unit, particularly a kind of light-weight thermal-insulation wall plate.

Background technology

Along with novel energy-saving construction material and technology are carried out by country, Light insulated wall panels has multiple pattern in recent years, it is lower to strengthen wallboard intensity such as gypsum plank, fine coal hawk, paper grass plate, and heat-insulating property is poor, and some ash wall body plate has also been used the chemical material of easy contaminated environment.And be the ash wall body plate of major ingredient with cement, between intensity and weight, there is contradiction, intensity is higher, and cement proportion is bigger, and cement and sand account for more than 50%, and the deadweight of ash wall body plate is very heavy, its insulation, energy-conservation and soundproof effect is all bad; Be weight reduction, add a large amount of light materials as 50% above expanded perlite in cement, though deadweight reduces, the intensity of ash wall body plate descends significantly, does not reach building requirements.

Summary of the invention

The object of the present invention is to provide a kind of body light, insulation, the light heat-insulating cement wall panel that intensity is high, purpose of the present invention realizes by following mode, ash wall body plate raw material material package is drawn together high alumina cement, flyash, straw fiber or wood fiber, blowing agent, it is characterized in that also comprising haydite and rubber latex cement modifier, the raw material weight proportioning is as follows:

High alumina cement 20%～30%, haydite (diameter 2～3.5mm) 20%～30%, flyash 25%～35%, stalk fibre or wood fiber 5%～10%, hydrogen peroxide blowing agent 3%～5%, rubber latex cement modifier 0.5%～2%.For gaining in strength, the present invention builds steel mesh with the ash wall body plate slurry and is fixed in the ash wall body plate.Because the present invention has added haydite and has replaced sand as the cement lightweight aggregate in cement, and in ash wall body plate, add steel mesh, add straw fiber or wood fibre simultaneously, ash wall body plate compressive strength and flexural strength height under the light prerequisite of body have been guaranteed, the rubber latex cement modifier can improve the water resistance of ash wall body plate, increase toughness, ash wall body plate of the present invention has that body is light, good heat preservation performance, advantage that intensity is high, every index is all far above in the past light body plate of cement JRC plate, chloro-magnesium cement and gypsum light partition board, its compressive strength 〉=10MPa can directly do exterior wall.

The specific embodiment

One, raw material weight proportioning: high alumina cement 20%, haydite 30%, flyash 35%, stalk fibre 10%, hydrogen peroxide blowing agent 3%, rubber latex cement modifier 2%.Adopt the casting method moulding, aforementioned base materials is converted water and is stirred into slurry, with slurry evenly casting in mould, when reaching 1.5 millimeters thickness, lay glass fiber grid cloth waters the mixed slurry of one deck again, lay gauze wire cloth when reaching 10 millimeters thickness, build slurry again to specific thickness, put one deck foamed polystyrene board, build slurry and to mid portion, lay steel mesh and glass fiber grid cloth upward, flatten upper surface by the symmetry requirement, the health appropriate time gets final product demoulding.Block and simple sanding according to certain specification, transport the scene of building, put into later stage age hardening workshop and deposit, put in some way neatly, guarantee indeformablely, carry out the later stage health, after waiting to reach prescribed strength, can sell in the accumulating field.

Two, raw material weight proportioning: high alumina cement 30%, haydite 20%, flyash 30%, stalk fibre 15%, hydrogen peroxide blowing agent 4.5%, rubber latex cement modifier 0.5%.Casting method is same.

Three, raw material weight proportioning: high alumina cement 28%, haydite 28%, flyash 25%, wood fiber 13%, hydrogen peroxide blowing agent 5%, rubber latex cement modifier 1%.Casting method is same.

Claims

1, light heat-insulating cement wall panel, raw material comprise high alumina cement, flyash, straw fiber or wood fiber, blowing agent, it is characterized in that also comprising haydite and rubber latex cement modifier, and the raw material weight proportioning is as follows:

High alumina cement 20%～30%, haydite 20%～30%, flyash 25%～35%, stalk fibre or wood fiber 5%～10%, hydrogen peroxide blowing agent 3%～5%, rubber latex cement modifier 0.5%～2%.

2, light heat-insulating cement wall panel according to claim 1 is characterized in that with the ash wall body plate slurry steel mesh being built and is fixed in the ash wall body plate.
