Abstract
The invention relates to a method for producing acrylic adhesive. Hydrolysis resistance of the acrylic adhesive is improved through branched-chain combining, as is verified in the test, the reaction time of branched-chain combining is determined by temperature, and the higher the temperature is, the shorter is the branched-chain combining time. Besides, triethylene diamine is selected as a catalyst, therefore, the branched-chain combining effect is good, and the hydrolysis resistance of the acrylic adhesive is greatly improved compared with that of conventional acrylic adhesive. According to the method, the acrylic adhesive is modified with the branched-chain combing method, and therefore clothes with lining cloth made of the acrylic adhesive are not resistant to water washing.
Description
Technical field
The present invention relates to the TEXTILE CHEMICALS field, specifically a kind of acrylate adhesive production method, be mainly used in the textile garment lining cloth.
Background technology
The relation of the mankind and chemical industry is very close, in the modern life, almost all be unable to do without Chemicals whenever and wherever possible, from material lifes such as clothing, food, shelter, row to cultural lives such as culture and arts, amusements, all needs Chemicals to serve for it.Some Chemicals, in human development history, plays epoch-making vital role.Their production and application, even representing certain historical stage of human civilization.
The thing of the acrylic acid or the like of usually saying, the overwhelming majority refers to the compound of esters of acrylic acid, say that exactly acrylic acid or the like is the most appropriate, and structure is esters of acrylic acid.Vinylformic acid is CH
2=CH-COOH, be the most basic industrial chemicals, generally can not be used on the end product of fine chemistry industry, has very strong acidity, and corrodibility approaches hydrochloric acid, generally is used for the synthesis of acrylic ester compound.Acrylate is that vinylformic acid obtains with after pure the reaction, CH
2=CH-COOR(R is alkyl).The two is different, and acrylate can synthesize a lot of oligopolymer and multipolymer, and these oligopolymer or multipolymer, referred to as resin, just can be done coating, printing ink, tackiness agent etc.So just can be described as acrylic adhesives, or acrylic binder.For the acrylate adhesive of Pading cloth, can meet dry-cleaning but washing performance is poor on market, generally use the clothes of acrylate adhesive all to need to indicate and should not wash.Also there is no at present that a kind of production technique is simple, production cost is low, and by conjunction with side chain, having improved washing performance, thereby meet the CALCIUM ACRYLATE sizing agent required as Pading cloth.
Summary of the invention
The present invention is just for above technical problem, provides that a kind of production technique is simple, production cost is low, and by conjunction with side chain, having improved washing performance, thereby meet the CALCIUM ACRYLATE sizing agent required as Pading cloth.
The present invention is achieved through the following technical solutions.
A kind of acrylate adhesive production method, its process is: at first by polyhydric alcohol polymer, acrylic ester monomer, the chainextender dehydration is standby, lead to nitrogen in reactor, add polyhydric alcohol polymer, add in addition catalyzer, stir and drip polyisocyanates, be warming up to 60～110 ℃, be incubated 3～6 hours, add chainextender, and add acrylic ester monomer, when in reactant, the quality percentage composition of NCO group reaches 0.05～10%, add acrylate, then above-mentioned solution is down to room temperature, add initiator, and be added in the deionized water solution that is added with tensio-active agent, stir on dropping limit, limit, it is dispersed into to the urethane pre-emulsion of certain particle diameter, finally above-mentioned pre-emulsion is joined in reactor, pass into nitrogen, be warming up to 50～80 ℃ and react 3～6 hours, then be down to the room temperature discharging.Described catalyzer is triethylene diamine, and described chainextender is benzoyl peroxide, and described initiator is Potassium Persulphate, and described acrylate is acrylic acid hydroxy alkyl fat.Polyhydric alcohol polymer, acrylic ester monomer, acrylate, catalyzer, chainextender, the initiator that described production method is used, the deionized water solution weight ratio that is added with tensio-active agent are 200:3000:300:2:1:1:3500.
Adopt the method for the invention to make acrylate adhesive generation modification by the method in conjunction with side chain, thereby solved the not laundry-resistant difficult problem of clothes of lining cloth use acrylate adhesive.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1:
A kind of acrylate adhesive production method, its process is: at first by the 200Kg polyhydric alcohol polymer, the 3000Kg acrylic ester monomer, the dehydration of 300Kg benzoyl peroxide is standby, and lead to nitrogen in reactor, add the 200Kg polyhydric alcohol polymer after dehydration, add in addition the 1Kg triethylene diamine, stir and drip the 500Kg polyisocyanates, be warming up to 110 ℃, be incubated 3 hours, add the 2Kg benzoyl peroxide, and add the 3000Kg acrylic ester monomer, fully after reaction, add 300Kg acrylic acid hydroxy alkyl fat, then above-mentioned solution is down to room temperature, add the 1Kg Potassium Persulphate, and be added in the deionized water solution that 3500Kg is added with tensio-active agent, stir on dropping limit, limit, it is dispersed into to the urethane pre-emulsion of certain particle diameter, finally above-mentioned pre-emulsion is joined in reactor, pass into nitrogen, be warming up to 80 ℃ and react 3 hours, then be down to the room temperature discharging.
Embodiment 2:
A kind of acrylate adhesive production method, its process is: at first by the 20Kg polyhydric alcohol polymer, the 300Kg acrylic ester monomer, the dehydration of 30Kg benzoyl peroxide is standby, and lead to nitrogen in reactor, add the 20Kg polyhydric alcohol polymer after dehydration, add in addition the 0.1Kg triethylene diamine, stir and drip the 50Kg polyisocyanates, be warming up to 60 ℃, be incubated 6 hours, add the 0.2Kg benzoyl peroxide, and add the 300Kg acrylic ester monomer, fully after reaction, add 30Kg acrylic acid hydroxy alkyl fat, then above-mentioned solution is down to room temperature, add the 0.1Kg Potassium Persulphate, and be added in the deionized water solution that 350Kg is added with tensio-active agent, stir on dropping limit, limit, it is dispersed into to the urethane pre-emulsion of certain particle diameter, finally above-mentioned pre-emulsion is joined in reactor, pass into nitrogen, be warming up to 50 ℃ and react 6 hours, then be down to the room temperature discharging.
Through test, confirm, the high end of temperature, determine to finish the time of side reaction, and temperature is higher, and a knot time is shorter.In addition, select triethylene diamine as catalyzer, knot props up respond well, and hydrolytic resistance improves greatly than conventional acrylate adhesive.
