Description
Technical field
The invention belongs to building material field, specifically a kind of novel plant Quito function powerful adhesive for building and preparation method thereof.
Background technology
It is exactly relatively poor of adhesive property that most vegetable jelly in the market have a common defect, easily produces crack after mixing the putty powder, affect the effect of later stage decoration; Easily go mouldy, storage stability is very poor.The general VOC content of other chemical building adhesive is higher, contains formaldehyde, the hazardous and noxious substances such as acrylamide, and harm people's health is contaminate environment again.External similarly product effect is good, but selling at exorbitant prices can not be applied on a large scale.
?
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of novel plant Quito function powerful adhesive for building and preparation method thereof.
A kind of novel plant Quito function powerful adhesive for building, is characterized in that its raw material by following formulation by weight makes: 120-200 parts, water, 2-10 parts of polyvinyl alcohol resins, 12-25 parts of soybean protein isolates, 0.5-7 parts of Guanidinium hydrochlorides, sodium sulfate 0.3-6 part.
Described a kind of novel plant Quito function powerful adhesive for building, is characterized in that its raw material by following formulation by weight makes: 150-180 parts, water, 4-8 parts of polyvinyl alcohol resins, 15-20 parts of soybean protein isolates, 1-6 parts of Guanidinium hydrochlorides, sodium sulfate 0.8-5 part.
Described a kind of novel plant Quito function powerful adhesive for building is characterized in that described polyvinyl alcohol resin carries out proportioning according to the different polymerization degree according to following parts by weight: polyvinyl alcohol resin 24-88 1-4 part, polyvinyl alcohol resin 17-88 2-5 part.
The preparation method of described a kind of plant base multifunctional powerful adhesive for building, is characterized in that comprising the steps:
(1) to the modification of soybean protein isolate: water and soybean protein isolate are mixed to add in reactor and heat up, add Guanidinium hydrochloride, add sodium sulfate, mixing and stirring, isothermal reaction, cooling discharge, in whole reaction process, control stirring velocity, bubble in a large number to prevent glue;
(2) dissolve polyvinyl alcohol resin: polyvinyl alcohol resin is particulate state, first adds hot water to stir, and then heating, stir simultaneously, and polyvinyl alcohol resin is dissolved completely;
(3) synthetic building adhesive: the polyvinyl alcohol resin cooling by having dissolved, according to formula rate, add the soybean isolated protein liquid that modification is good, stir and get final product barrelling.
The preparation method of described a kind of novel plant Quito function powerful adhesive for building, it is characterized in that in step (1) water and soybean protein isolate are mixed to add in reactor being warming up to 30-40 ℃, preferably 35 ℃, add Guanidinium hydrochloride, mixing and stirring, after 5-20 minute, add sodium sulfate, preferably 10 minutes, isothermal reaction 2h, cooling discharge, in whole reaction process, controlling stirring velocity is 50-100 r/min, and preferably 60～80 r/min, bubble in a large number to prevent glue.
The preparation method of described a kind of novel plant Quito function powerful adhesive for building, is characterized in that in step (2) first adding the hot water of 50-60 ℃ to stir 40 minutes, then is heated to 80-90 ℃, stirred simultaneously 1 hour, and polyvinyl alcohol resin is dissolved completely.
The preparation method of described a kind of novel plant Quito function powerful adhesive for building, it is characterized in that, in step (3), the polyvinyl alcohol resin dissolved is cooled to 30-40 ℃, preferably 35 ℃, according to formula rate, add the soybean isolated protein liquid that modification is good, stir and get final product barrelling.
Soybean protein isolate is very importantly integral part of soybean, contains abundant active group, has the advantages such as renewable, that source is wide, biodegradable, can be used as the main raw material for preparing environment-friendly material.But the structures shape of soybean protein isolate self its bonding strength when the architecture adhesion agent not high, poor water resistance, easily go mouldy, storage period is shorter, must be through the people for modification to improve its integrated application performance.In pure natural soybean molecule, on polypeptide chain, the overwhelming majority's polarity and non-polar group and soy-protein molecule form stable multilevel hierarchy by hydrogen bond, Van der Waals force, electrostatic interaction, hydrophobic interaction etc., thereby form the spheroid of fine and close combination, wetting ability is strong, hydrophobicity is poor, during as building adhesive, water tolerance is poor, and bonding strength is less.As building adhesive, must allow protein molecule disperse and launch by its modification, polarity and non-polar group more expose, thereby can interact to improve its bonding strength with grout.
After in sand-cement slurry, adding building adhesive of the present invention, can form one deck glued membrane on the initial setting time surface, this is in the characteristic that runs into air meeting conjunctiva because of polyvinyl alcohol.Due to the characteristic of modified soybean protein isolate, make this tunic very evenly.Because the soybean protein isolate of polyvinyl alcohol and modification can adsorb a large amount of moisture, make in water and can discharge slowly moisture in the aquation engineering, make cement can spend a very well hydration process.Soybean protein isolate through modification has good cohesive strength simultaneously, makes sand-cement slurry more firm in building operation, does not ftracture.Because making the present invention, above-mentioned reason effectively prevents the generation of crackle.The present invention simultaneously is a kind of product of complete environmental protection, and the preparation method is simple and convenient, and cost is lower, and material is extensive.
