Abstract
The invention relates to a universal environment-friendly building glue and a preparation method thereof. Polyvinyl alcohol, acrylamide, sodium bisulfite, ammonium persulfate, VAE emulsion, a defoamer, a corrosion remover and water are taken as materials to perform polymerization reaction, so the water-soluble polymer glue is formed. The production process is simple; the building glue is free of free formaldehyde, high in bonding strength and good in water resistance; the building glue is added with putty powder so as to be used for universally puttying inner and outer walls, lubrication in batch puttying is realized, moisture is preserved, cracking is prevented, the powder does not fall, and the environment is protected.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of preparation method of building glue.
Background technology
At present, building glue market used has two classes: formaldehyde polyvinyl acetal water and the blended glue of polyvinyl alcohol/polyacrylamide.The preparation process of formaldehyde polyvinyl acetal water needs to add formaldehyde, and reacted glue contains free formaldehyde.Polyvinyl alcohol/polyacrylamide blended glue cohesive strength is low, anti-freezing property is poor.In addition the PVA alcoholysis degree that above two kinds of glue use is 99%.
Summary of the invention
It is high that the technical problem to be solved in the present invention is to provide a kind of cohesive strength, water-fast, good frost resistance, and formaldehydeless Green environmental-protection building glue and preparation method thereof.
Technical solution problem of the present invention, adopts following technical scheme:
Each raw material proportioning by weight of the present invention's universal environment protection architecture glue is:
Polyvinyl alcohol 20 ~ 40 parts, acrylamide 20 ~ 40 parts, ammonium persulphate 0.02 ~ 0.04 part, sodium bisulfite 0.01 ~ 0.02 part, VAE emulsion 40 parts, defoamer 0.1 part, sanitas 0.1 part, 900 parts, water.
The technical requirements of above-mentioned each raw material is:
Polyvinyl alcohol alcoholysis degree 88%, the polymerization degree 2400;
The mass content of the ethene of VAE (Vinyl Acetate Copolymer-ethylene copolymer) emulsion is 17%, and the mass content of non-volatile matter is 55%;
Ammonium persulphate (SILVER REAGENT), sodium bisulfite (SILVER REAGENT), all the other raw materials are that industrial raw material is commonly used in market.
Above-mentioned building glue is prepared as follows:
Step 1: add water and defoamer by proportioning in reactor, then adds polyvinyl alcohol and acrylamide and stirs 0.5 hour, be warming up to 90 DEG C and be incubated 1 hour, polyvinyl alcohol and acrylamide are dissolved completely;
Step 2: temperature of reaction kettle is controlled at 65 DEG C, then add sodium bisulfite and stir 5min, add ammonium persulphate again and stir 5 minutes, stopping stirring, leave standstill insulation reaction 4 hours, cool to 40 DEG C, add VAE emulsion and sanitas again, be uniformly mixed 0.5 hour, make material evenly blended, namely product is obtained, packaging discharging.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the invention provides a kind of preparation method of building glue, production technique is simple, and product is not containing formaldehyde, and environmental protection, use as building glue, inner, external wall can be general.
2, the present invention use in preparation alcoholysis degree be 88% polyvinyl alcohol, pass through polyaddition reaction, acrylamide forms larger molecular weight polymkeric substance, and then with VAE emulsion blending, this composition overcomes the defect of existing two kinds of glue, has that cohesive strength is high, good frost resistance, easily technical characteristics such as construction grade, and not containing harmful chemicals such as formaldehyde, environmental protection.
3, gained building glue of the present invention and existing two kinds of common building glue are carried out the contrast (non-volatile matter of three kinds of glue all with 6% for benchmark detects) of technical feature, result is as described in Table 1, building glue of the present invention is compared with formaldehyde polyvinyl acetal water, polyvinyl alcohol/polyacrylamide Blend rubber water as can be seen from the table, and frost resistance and cohesive strength are all significantly improved.
