Abstract
The present invention provides a chemical synthetic decorative board. It possesses the advantages of good fire-resistance, damp-proofing property, sound-insulating property and heat-insulating property. It is characterized by adding light material in raw material, so that it features light weight.
Description
The present invention relates to a kind of chemosynthesis dalle, specifically be meant a kind of light gypsum board.
In present building decorating industry, more and more stricter to the performance requriements of finishing material, especially require more and more higher to the fire line of material, moistureproofness, heat retaining property etc.Because these performances are directly connected to the safe handling of buildings, protection property and personnel safety all there is significance.Present most widely used have plastering and asbestos products, this different materials all has good fireproof heat insulating performance.But owing to the pollution of asbestos products to environment, its use range is more and more littler, is subjected to strict restriction the most at last, and plastering has easy-formation, low cost and other advantages, but mainly exist than great, be difficult for installing shortcomings such as poor, the easy fragmentation of moistureproofness.
At the weak point of above product, purpose of the present invention just provides a kind ofly has fire line, moistureproofness, heat retaining property, sound insulation preferably, and a kind of light gypsum board that intensity is big, proportion is lighter.
The purpose of art invention realizes in the following way: be main raw material, an amount of magnesium chloride, the magnesium oxide of interpolation with the gypsum, and add a certain amount of lightweight and add and fill material, also can adopt glasscloth or paper product as reinforcement material, after conventional industrial processes, make stock board.Add and fill material owing to added lightweight, thereby the product proportion of making is less.
Described lightweight is added and is filled material and be meant foam grain, plant powder.Can a kind ofly be used alone, but also also mix together.Formula for raw stock is: terra alba: magnesium oxide 54%: plant powder 22%: foam grain 3.2%: 1.8%.
Light gypsum board of the present invention has following advantage:
(1) proportion is less.Generally caning be controlled in proportion is below 1, to bring convenience to installation and transportation.
(2) fire protection flame retarding is good.After testing, oxygen index reaches 60.
(3) have good insulation, sound-proofing properties.
(4) humidity resistance is good, and it is indeformable to make moist.
(5) cost further reduces, and production technique is simple.
A kind of specific embodiment of the present invention is described below: produce this decorative sheet of one 33.5 jin, a traditional unit of weight, the desired raw material prescription is as follows: (1) terra alba: 17 jin, a traditional unit of weight, (2) magnesium oxide: 7 jin, a traditional unit of weight, (3) magnesium chloride: 6 jin, a traditional unit of weight, (4) plant powder: 1 jin, a traditional unit of weight, (5) foam grain: 0.5 jin, a traditional unit of weight, (6) water: 6 jin, a traditional unit of weight.Production technique is:
Batching-material loading-making sheet-drying-check
Claims (1)
- A kind of light gypsum board is characterized in that: the composition weight ratio in its prescription beyond the water is: (1) gypsum: 50-60%, (2) magnesium oxide: 20-30%, (3) magnesium chloride: 15-25%, (4) plant powder: 2-4%, (5) foam grain: 1-2%.
