Abstract
The invention discloses a special interface agent for moisture-proof water-proof gypsum blocks, belonging to the field of water prevention of building materials. The special interface agent comprises the following components in parts by weight: 50 parts of building gypsum powder, 20 parts of calcite powder, 15 parts of polyvinyl alcohol, 10 parts of potassium silicate and 5 parts of a water-retaining agent. A preparation method of the special interface agent comprises the following steps: (1) uniformly mixing 50 parts of the building gypsum powder, 20 parts of the calcite powder, 15 parts of polyving akohol, 10 parts of potassium silicate and 5 parts of the water-retaining agent to prepare a mixture, and packaging the mixture in a package bag for later use; (2) putting 100 parts of the mixture formed in the step (1) into a small bucket, then pouring 40-60 parts of water into the small bucket, and stirring to obtain the special interface agent for the moisture-proof water-proof gypsum blocks. The special interface agent is very good in interface property, the adhesion of putty and cement mortar to the surface of the gypsum blocks is greatly enhanced, the strength of the hardened mortar is improved, the late repair expense of a wall body is reduced, and the engineering cost is lowered.
Description
Technical field
The present invention relates to a kind of material of construction waterproof field, relate in particular to a kind of moistureproof and waterproof gypsum block special interface agent and preparation method thereof.
Background technology
Existing gypsum block there is no does surface interface processing, gypsum block water-intake rate is high, there is no the gypsum block surface blade coating putty of interface processing, the moisture of putty the inside is not just being absorbed by gypsum block before sclerosis, cause putty hollowing, flake, come off, if smear on gypsum block surface sand-cement slurry equally before sand-cement slurry sclerosis moisture just absorbed by gypsum block, cause sand-cement slurry hollowing, flake, come off, in the time pasting ceramic tile, also can there is hollowing, obscission in ceramic tile.Flake and come off due to the caused putty of gypsum block wall and sand-cement slurry, cause gypsum block wall engineering to be reprocessed even and do over again, allow enterprise suffer great financial loss.
Existing gypsum block wall there is no and do surperficial moistureproof and waterproof interface processing, causes putty and the sand-cement slurry quality problems that come off of flaking, thereby reduces this competitiveness of product in market.In gypsum block technical regulation JGJ/T201-2010, clearly interfacial agents processing should be done in regulation gypsum block surface, so the special moistureproof and waterproof interfacial agents of gypsum block is the market vacancy.
Summary of the invention
The invention provides a kind of moistureproof and waterproof gypsum block special interface agent and preparation method thereof, all do not do WATER REPELLENT, problems such as causing putty and sand-cement slurry hollowing, flake and come off in the gypsum block of solution prior art.
The present invention is achieved by the following technical solutions: moistureproof and waterproof gypsum block special interface agent, is made up of the component of following weight part: 50 parts of building gypsum plasters, 20 parts of coarse whitings, 15 parts of polyvinyl alcohol, 10 parts of potassium silicates, 5 parts of water-holding agents.
As preferably, described water-holding agent is polyacrylamide water-holding agent.
A method of preparing above-mentioned moistureproof and waterproof gypsum block special interface agent, comprises the following steps:
(1) by weight part be 50 parts of building gypsum plasters, 20 parts of coarse whitings, 15 parts of polyvinyl alcohol, 10 parts of potassium silicates, mixture is made in 5 parts of uniform mixings of water-holding agent, and it is for subsequent use that the mixture of formation packs packing bag packing into;
(2) mixture that is 100 by the weight part forming in step (1) is put into keg, then pours the water stirring that weight part is 40-60 into, has stirred rear formation moistureproof and waterproof gypsum block special interface agent.
Beneficial effect of the present invention is: interface property of the present invention is very strong, greatly improves putty and the sand-cement slurry sticking power on gypsum block surface, the strength increase of self after mortar hardening, thus reduce the maintenance cost in body of wall later stage, reduce engineering cost.
