Description
Technical field
It is the present invention relates to a kind of gypsum water-based emulsion, in particular to a kind of for improving gypsum performance in mixed process
Water-based emulsion.
Background technique
Gypsum is a kind of widely used construction material and industrial materials.In recent years, in the decoration of architecture indoor and finishing
There are many middle application, especially in the decoration and finishing of home dwelling.Compared with other same type of material of application, plastering has
The feature that quality is relatively light, intensity is high, fire protecting performance is good, the plate made of this material, flame-retardant grade are equal
It is one of the preferred material of various environment indoor decoratings for level-one.However, traditional gypsum directly adopt water cure, at
The mode of type, the problems such as often will appear rough surface in actual use, lose powder, fall off, especially in southern high-temperature high humidity
In the environment of, the phenomenon that gypsum after solidification there is also cracking, jaundice, deform, fall off, seriously affects routine use or even builds
Build safety.Therefore, it is necessary to improve to existing gypsum performance, shape can be kept well, is not fallen off, and
It is easy to operate.
Summary of the invention
In consideration of it, the present invention proposes a kind of water-based emulsion for improvement gypsum performance in mixed process, used in gypsum
The effect of water is substituted in the process, application method is simple, and the gypsum after curing molding is hard, smooth, surface is not cracked, do not lose powder,
It does not fall off.
The technical scheme of the present invention is realized as follows:
A kind of water-based emulsion for improvement gypsum performance in mixed process, the lotion includes following raw material: polyethylene
Alcohol, silicone, catalyst, fungicide, defoaming agent, soft water.
Further, the lotion is formed according to the weight ratio of following raw material: 5-10 parts of polyvinyl alcohol, 20-30 parts of silicon substrates
Resin, 10-30 part catalyst, 1-2 parts of fungicide, 0.5-1 parts of defoaming agents, 27-63.5 parts of soft water.
Further, the polyvinyl alcohol is one or more compounding mixtures that the trade mark is 0599,0499 and 1788.This
The molecular weight and alcoholysis degree of the polyvinyl alcohol of the trade mark are more suitable for formula of the invention.
Further, the silicone be dimeticone water solubility siloxanes, vaseline, silicone oil it is one or more.
Further, the catalyst is the one or two of organotin, titanate esters.
Further, the fungicide is isothiazolinone biocide agent.
Further, the defoaming agent is polyoxyethylene polyoxypropylene pentaerythrite ether, polyoxyethylene polyoxy propyl alcohol amidogen ether
One or two.
Further, sealing is placed when the lotion stores, and transport temperature is not less than 15 DEG C, and temperature crosses low viscosity and is easy to increase
Greatly, lotion will be caused not to be available.
Further, it is using the method for the lotion: the lotion is mixed with gypsum according to mass ratio 1:2, and is stirred
After mixing uniformly, solidifies at room temperature, is molded into required shape.
Compared with prior art, the beneficial effects of the present invention are:
The present invention makes gypsum be easy to bond, forms, good barrier property using polyvinyl alcohol composite mixture, compounds so that lotion
It is more stable, it is easy to storage and transport.The present invention by be added silicone make lotion have block water, hydrophobic performance, prevent
Gypsum water suction weight gain, normal-temperature water are impregnated for 24 hours, and weight gain is no more than 5%, improve the service life of finished product, while it is anti-that fungicide is added
Only lotion is rotten, improves the lotion shelf-life.The present invention improves the adhesion strength and compatibility of lotion by the way that catalyst is added, and prevents
Gypsum picking, layering.The present invention greatly reduces the foam generated in lotion use process by stirring by the way that defoaming agent is added, from
And reduce because gypsum hole caused by foam, it is hollow the problems such as, and reduce gypsum water absorption rate.Application method of the present invention is simple, makes
The gypsum made of the present invention is hard, it is smooth, be not cracked, and manufactured gypsum can be carved, polish, and can be used for sculpture, decoration, dress
The outdoor locations such as pool, long-term rain corrode or it is sunlit under the conditions of can keep shape well, water absorption rate is low, does not take off
It falls, is indeformable, is non-yellowing, not losing powder, suitable for the biggish environment of humidity or more harsh natural conditions.
