Abstract
A water-proof white emulsoid is prepared from ethylene acetate, styrene, butyl acrylate, acrylic acid, emulsifier OP, sodium laurylsulfate, emulsifier S, ammonium persulfate, sodium carbonate, thickening agent NA, zinc acetate and water through mixing, emulsifying, triggering, stabilizing and polymerization, and features simple process, and excellent water-proofing nature.
Description
The invention belongs to water-resistant adhesive, relate to a kind of improvement existing milky white adhesive.
Existing milky white adhesive is widely used in fields such as building, coating, decoration, furniture manufacturing, passenger train, automobile, shipbuilding, printing, papermaking, textile finishing, packing are bonding.The shortcoming of milky white adhesive is a poor water resistance, during with the bonding timber of milky white adhesive, soaks in water or easy to crack during life-time service under wet condition.More be unable to undergo hot water and boiling water digestion with milky white adhesive adherent timber.For the bad problem of the water tolerance that solves Emulsion Adhesive, adopt the handing-over technology usually, need high-temperature cross-linking to handle.Emulsion is crosslinked need carry out under higher temperature.Because the milky white adhesive water tolerance is bad, has limited the use of milky white adhesive to a certain extent, within the specific limits.
The purpose of this invention is to provide a kind of waterproof adhesive, solved the water-fast bad of milky white adhesive, and made the application of milky white adhesive in all trades and professions more extensive.
Waterproof adhesive provided by the invention is to make by the good monomer copolymerization of vinyl acetate between to for plastic and water tolerance, and further improve water tolerance by the cold cross-linking technology, the good comonomer of water tolerance has vinylbenzene, ethyl propenoate, butyl acrylate etc., comonomer accounts for 40-70%, vinyl acetate between to for plastic and 60-30%.Adjust each component ratio as required, acrylate is many more, better performances; Vinylbenzene is many more, and cost is low more.The present invention adopts the cold cross-linking technology, adopts zinc acetate, calcium ion linking agent.Since adopted with good monomer copolymerization of water tolerance and normal temperature under crosslinking technological, obtained the milky white adhesive of water tolerance excellence.
Concrete implementing process is to get by raw material percentages:
Vinyl acetate between to for plastic 10-30%, vinylbenzene 10-30%, butyl acrylate 5-15%, vinylformic acid 0.5-4%, polyoxyethylene nonylphenol ether 0.2-2%, sodium lauryl sulphate 0.1-1%, emulsifying agent S0.2-2%, ammonium persulphate 0.1-1%, yellow soda ash 0.001-0.1%, thickening material NA0.1-2%, zinc acetate 0.05-1%, water 20-60%.
The present invention operates as follows:
Vinyl acetate between to for plastic 120kg, vinylbenzene 120kg, butyl acrylate 60kg, vinylformic acid 15kg are made mix monomer;
With 105kg hot water dissolving polyoxyethylene nonylphenol ether 6kg, sodium lauryl sulphate 1.5kg, emulsifying agent S (self-control) 4.5kg.This emulsifier solution is an emulsion.
Dissolving initiator:, make the dissolving initiator with 45kg dissolving 1.5kg ammonium persulphate.
In 1000 liter enamel reaction stills, add 150kg water, add 0.6kg yellow soda ash, thickening material NA (self-control) 5.73kg, dissolving.
With 97.0kg emulsion mix monomer, the 20.0kg emulsion is added reactor heat up with steam.
With 45kg water dissolution 1.5kg ammonium persulphate, take out the 11.5Kg initiator solution.
When temperature in the kettle reaches 78 ℃, the 11.5Kg initiator is added in the reactor; The remaining 35Kg initiator solution of a part adds in the emulsified monomer.
Behind initiated polymerization, under 80 ℃~85 ℃ temperature, continue polyreaction, add emulsified monomer continuously.Appending monomer in two hours finishes.
After monomer adds, be warming up to 88 ℃, kept two hours.Add acetic acid 0.63Kg.
Be cooled to 50 ℃, filter.Promptly make waterproof adhesive.
Boiled 8 hours at 100 ℃ during with this products with adhesive glued board, do not ftracture.At room temperature soak and do not ftracture in 2 months.
Positively effect of the present invention is that waterproof adhesive has been compared three advantages with common milky white adhesive: 1, water resistance excellence, and anti-30 ℃ of water loggings are common water tolerance, and anti-60 ℃ of water loggings are excellent water tolerance, and good 100 ℃ of poach are water tolerance.The invention provides the anti-100 ℃ of boiling water of waterproof adhesive and boil, cost is low, owing to introduce styrene monomer, cost reduces significantly, and vinylbenzene is 60% of vinyl acetate between to for plastic price, and water tolerance increases substantially.3, easy to use.General milky white adhesive will improve water tolerance, adopts crosslinking technological to need 160 ℃, uses inconvenience, can't use under the usual conditions.Waterproof adhesive provided by the invention is easy to use, and is identical with common milky white adhesive using method, had water tolerance by bonding material.
Specific embodiments of the invention are as follows:
Get vinyl acetate between to for plastic 18.87%, vinylbenzene 18.87%, butyl acrylate 9.44%, vinylformic acid 2.36%, polyoxyethylene nonylphenol ether 0.94%, sodium lauryl sulphate 0.24%, emulsifying agent S0.71%, ammonium persulphate 0.24%, yellow soda ash 0.09%, thickening material NA0.9%, zinc acetate 0.1%, water 47.7% by raw material per-cent.
The present invention operates as follows:
Vinyl acetate between to for plastic 120kg, vinylbenzene 120kg, butyl acrylate 60kg, vinylformic acid 15kg are made mix monomer;
With 105kg hot water dissolving polyoxyethylene nonylphenol ether 6kg, sodium lauryl sulphate 1.5kg, emulsifying agent S (self-control) 4.5kg.This emulsifier solution is an emulsion.
Dissolving initiator:, make the dissolving initiator with 45kg dissolving 1.5kg ammonium persulphate.
In 1000 liter enamel reaction stills, add 150kg water, add 0.6kg yellow soda ash, thickening material NA (self-control) 5.73kg, dissolving.
With 97.0kg emulsion mix monomer, the 20.0kg emulsion is added reactor heat up with steam.
With 45kg water dissolution 1.5kg ammonium persulphate, take out the 11.5Kg initiator solution.
When temperature in the kettle reaches 78 ℃, the 11.5Kg initiator is added in the reactor; The remaining 35Kg initiator solution of a part adds in the emulsified monomer.
Behind initiated polymerization, under 80 ℃~85 ℃ temperature, continue polyreaction, add emulsified monomer continuously.Appending monomer in two hours finishes.
After monomer adds, be warming up to 88 ℃, kept two hours.Add acetic acid 0.63Kg.
