Abstract
The invention relates to the technical field of doping agents of gypsum products, and in particular relates to a gypsum water-resistant agent. The gypsum water-resistant agent disclosed by the invention is prepared from the following various materials in percentage by weight: 20-50% of pure acrylic latex powder, 20-40% of coal ash, 1-2% of an early strength agent, 0.5-1% of ligneous calcium, and 0.1-0.5% of citric acid, wherein the early strength agent is anhydrous sodium sulfate or calcium chloride. The invention aims to provide the gypsum water-resistant agent which is high in water-resistant property and low in price.
Description
Technical field
The present invention relates to the technical field that plastering mixes agent, specifically a kind of water-proof gypsum agent.
Background technology
Plastering (as Thistle board, plasterboard hollow lath, fibrous plaster etc.), water resistance is all poor, use in water, under moist or drying and watering cycle condition, intensity can reduce greatly, loses intensity even completely, makes plasterboard be subject to havoc.For improving the water tolerance of plastering, what have adds the organism such as various water-soluble synthetic resin, pitch, paraffin emulsion, polyvinyl alcohol in gypsum, or composes with hydrophobic nature, or improves the compactness of its structure, to reach the object improving its water tolerance.But these admixtures adopted at present, some prices too high (the thousands of unit of every tondal), some meetings reduce the intensity of plastering.
Summary of the invention
The object of the invention is to be to provide a kind of water tolerance strong, cheap water-proof gypsum agent.
The technical solution used in the present invention is, a kind of water-proof gypsum agent, and described each material is by following weight percent composition: pure third latex powder 20-50%, flyash 20-40%, hardening accelerator 1-2%, wooden calcium 0.5-1%, citric acid 0.1-0.5%.
Say further, described hardening accelerator is: anhydrous sodium sulphate, calcium chloride.
Advantage of the present invention, after mixing gypsum mix, can significantly improve the water tolerance of plastering, can't reduce intensity and the weather resistance of goods.
Embodiment
The present invention is further described with the following Examples.
Embodiment 1, a kind of water-proof gypsum agent, described each material is by following weight percent composition: pure third latex powder 20%, flyash 40%, hardening accelerator 1%, wooden calcium 1%, citric acid 0.1%; Described hardening accelerator is: anhydrous sodium sulphate, calcium chloride.
Embodiment 2, a kind of water-proof gypsum agent, described each material is by following weight percent composition: pure third latex powder 50%, flyash 20%, hardening accelerator 2%, wooden calcium 0.5%, citric acid 0.5%; Described hardening accelerator is: anhydrous sodium sulphate, calcium chloride.
Embodiment 3, a kind of water-proof gypsum agent, described each material is by following weight percent composition: pure third latex powder 35%, flyash 30%, hardening accelerator 1.5%, wooden calcium 0.75%, citric acid 0.3%; Described hardening accelerator is: anhydrous sodium sulphate, calcium chloride.
Should be understood that this embodiment is only not used in for illustration of the present invention to limit the scope of the invention.In addition, should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the protection domain that the application's appended claims limits equally after having read the content that the present invention lectures.
Claims (2)
1. a water-proof gypsum agent, is characterized in that, described each material is by following weight percent composition: pure third latex powder 20-50%, flyash 20-40%, hardening accelerator 1-2%, wooden calcium 0.5-1%, citric acid 0.1-0.5%.
2. a kind of water-proof gypsum agent according to claim 1, it is characterized in that, described hardening accelerator is: anhydrous sodium sulphate, calcium chloride.
