Description
Technical field
The invention belongs to building material field, specifically a kind of environmentally friendly plant base building adhesive and preparation method thereof.
Background technology
It is exactly the poor of adhesive property comparison that most vegetable jelly in the market have a common defective, produce easily the crack after mixing the putty powder, affect the effect of later stage decoration, the VOC content that has simultaneously is higher, contain formaldehyde, the hazardous and noxious substances such as acrylamide, harm people's health is contaminate environment again.External similarly product effect is good, but selling at exorbitant prices can not be used 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 environmentally friendly plant base building adhesive and preparation method thereof.
A kind of environmentally friendly plant base building adhesive is characterized in that its raw material by following formulation by weight makes: 120-200 parts in water, 2-10 parts of polyvinyl alcohol resins, 12-25 parts of soybean protein isolates, 0.5-7 parts of sodium lauryl sulphate.
Described a kind of environmentally friendly plant base building adhesive is characterized in that its raw material by following formulation by weight makes: 150-180 parts in water, 4-8 parts of polyvinyl alcohol resins, 15-20 parts of soybean protein isolates, 1-5 parts of sodium lauryl sulphate.
Described a kind of environmentally friendly plant base building adhesive 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 22-99 1-4 part, polyvinyl alcohol resin 20-99 2-5 part.
The preparation method of described a kind of environmentally friendly plant base building adhesive is characterized in that comprising the steps:
(1) to the modification of soybean protein isolate: will water and soybean protein isolate mix to add in the reactor and heat up, add sodium lauryl sulphate, mixing and stirring, add linking agent behind the certain hour, isothermal reaction, cooling discharge is controlled stirring velocity in whole reaction process, bubble in a large number to prevent glue;
(2) dissolve polyvinyl alcohol resin: polyvinyl alcohol resin is particulate state, adds first hot water and stirs, and then heating is stirred simultaneously, and polyvinyl alcohol resin is dissolved completely;
(3) synthetic building adhesive: will dissolve good polyvinyl alcohol resin cooling, and add the good soybean isolated protein liquid of modification according to formula rate, stirring gets final product barrelling.
The preparation method of described a kind of environmentally friendly plant base building adhesive, it is characterized in that to be warming up to 30-40 ℃ in water and the soybean protein isolate mixing adding reactor in the step (1), preferred 35 ℃, add sodium lauryl sulphate, mixing and stirring, add the linking agent that accounts for mixture 0.2-0.8% weight after 30 minutes, the preferred linking agent that accounts for mixture 0.3-0.6% weight that adds, isothermal reaction 1h, cooling discharge, the control stirring velocity is 50-100 r/min in whole reaction process, and preferred 60～80 r/min bubble in a large number to prevent glue.
The preparation method of described a kind of environmentally friendly plant base building adhesive, the hot water that it is characterized in that adding first in the step (2) 50-60 ℃ stirred 40 minutes, then was heated to 95-100 ℃, stirred simultaneously 1 hour, and polyvinyl alcohol resin is dissolved completely.
The preparation method of described a kind of environmentally friendly plant base building adhesive, it is characterized in that to dissolve in the step (3) good polyvinyl alcohol resin and cool to 30-40 ℃, preferred 35 ℃, add the good soybean isolated protein liquid of modification according to formula rate, stirring gets final product barrelling.
Soybean protein isolate is very importantly integral part of soybean, contains abundant active group, has the advantages such as renewable, that the source is wide, biodegradable, can be used as the main raw material of preparation 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 is easily gone mouldy, storage period is shorter, must through the people for modification to improve its integrated application performance.In pure natural soybean molecule, the overwhelming majority's polarity and non-polar group and soy-protein molecule consist of stable multilevel hierarchy by hydrogen bond, Van der Waals force, electrostatic interaction, hydrophobic interaction etc. on the polypeptide chain, thereby form the spheroid of fine and close combination, wetting ability is strong, hydrophobicity is relatively poor, water tolerance is relatively poor during as building adhesive, and bonding strength is less.As building adhesive, must allow protein molecule disperse and expansion by to its modification, polarity and non-polar group more expose, thereby can interact to improve its bonding strength with grout.
Behind the adding building adhesive of the present invention, can form one deck glued membrane on the initial setting time surface in sand-cement slurry, this is in the characteristic that runs into air meeting conjunctiva because of polyvinyl alcohol.Because the characteristic of modified soybean protein isolate, make this tunic very evenly.Because the soybean protein isolate of polyvinyl alcohol and modification can both adsorb a large amount of moisture, so that in water, can discharge slowly moisture in the aquation engineering, so that cement can be spent a very well hydration process.Soybean protein isolate through modification has good cohesive strength simultaneously, so that sand-cement slurry is more firm in building operation, does not ftracture.Owing to making the present invention, above-mentioned reason effectively prevents the generation of crackle.Simultaneously the present invention 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.
