Abstract

A light cement slab for building features that in its manufacture, light filler is used. Its advantages are light weight, high strength, resistance to water and fire and insulation nature to sound and temp, and low cost.

Description

Light cement slab
The present invention relates to a kind of light building material, specifically be meant a kind of light cement slab.
In present cement sheet material for building, the most frequently used is cement sheet material, its major advantage is the intensity height, cost is lower, easy construction, but it is bigger that the deficiency of its maximum is a proportion, make troubles for transportation and use, for overcoming above-mentioned deficiency, the hollow cement board material has appearred on the market, the novel architecture material of different varietiess such as gypsum sheet material, purpose is to reduce proportion, increase heat-insulating property, improved sheet material has reached the purpose that reduces proportion, but also brought new deficiency, as: the hollow cement board undercapacity, the plasterboard waterproof, moistureproofness is poor, weather resistance deficiency etc.
At the above weak point of currently available products, purpose of the present invention just provides a kind ofly has intensity, fire line, water-repellancy, moistureproofness, heat retaining property, sound insulation preferably preferably, and the less a kind of light cement slab of proportion.
The objective of the invention is to realize in the following way: be major ingredient with the Portland cement, dose a certain amount of light material therein, after conventional industrial processes, make stock board.Owing to added lightweight filler, thereby the sheet material proportion of making is less, and other various performances all reach requirement.
Described lightweight filler is meant foam grain, and raw material ratio is cement 25%-35% by volume, and foam grain is 75%-65%, and wherein with cement 30%, porous plastics 70% is best proportioning.
Light weight cement plate of the present invention has following advantage:
1, proportion is less.Generally can be controlled in about 1, bring great convenience for operation and transportation.
2, fire protection flame retarding is good.All reach the fireproof building material standard after testing.
3, has excellent insulating, sound-proofing properties.
4, waterproof, moistureproofness are good.It is indeformable to make moist.
5, cost further reduces, and production technique is simple.
6, has good intensity.
A kind of specific embodiment of the present invention is described below:
Batching (volume ratio: cement 30%, foam grain 70%, water is an amount of)-making sheet-drying.

Claims (2)

  1. A kind of light weight cement plate is characterized in that: in its prescription, volume percent is:
    (1) cement: 25%-35%,
  2. (2) light filler: 65%-75%,
    Its best proportioning is: cement 30%, light filler 70%, described light filler are foam grain.
