Abstract
The present invention relates to a preparation method of a water-soluble macromolecular quadripolymer softener. In the preparation method, cationic monomers, anionic monomers, non-ionic monomers and acrylamide have a polyreaction under the action of initiators for 4 to 8 hours at a temperature of 35 to 70 DEG C; alkali is added to the reaction products, the pH value of the products are regulated to 3.5 to 4.5, preservatives are added, and thus, the softener is prepared. Compared with the binary copolymer softeners and the terpolymer softeners, the softener used for caring hairs achieves favorable effect.
Description
The present invention relates to a kind of preparation method of water soluble quarternary copolymer softener.
Domestic hair softener commonly used mostly is two membered copolymers greatly, as homemade cationic quaternary ammonium polyacrylamide series products, as calcium light (Calgon) the product M550 of company.A small amount of is terpolymer, as calcium light (Calgon) the product M3330 of company, M2001 etc.Still find no the hair softener of quadripolymer in the market.Is that polymer based has been carried out research relatively from compatibility, conditioning property and tackifying three parts in the face of above-mentioned dimethyl diallyl ammonium chloride, the result shows: the terpolymer of dimethyl diallyl ammonium chloride/acrylic acid/methyl acrylate is better than the bipolymer of dimethyl diallyl ammonium chloride/methyl acrylate, more is better than the monobasic polymer (" daily chemical industry " 1999 year fifth phase) of dimethyl diallyl ammonium chloride.
The preparation method who the purpose of this invention is to provide a kind of softener of water soluble quarternary copolymer.
The present invention can realize by following technical proposals: at first drop into 72-88% (by weight percentage in the enamel reactor that has agitator and heating jacket, as follows) deionized water, the cationic monomer that adds 5-12% then, as allyl trimethyl ammonium chloride or acrylic acid trimethylamine ethyl ester ammonium chloride or methacrylic acid trimethylamine ethyl ester ammonium chloride or acrylamide propyl trimethyl ammonium chloride or Methacrylamide oxypropyl trimethyl ammonium chloride, the 3-10% anionic monomer, as acrylic or methacrylic acid, the 2-5% non-ionic monomer, as methyl acrylate or ethyl acrylate, the 2-5% acrylamide, mix, 0.1-0.3% by above-mentioned total amount adds peroxide or persulfuric acid salt initator, carries out the chain initiated polymerization.Control polymeric reaction temperature at 35-70 ℃, polymerization reaction time 4-8 hour.Polymerisation begins to carry out comparatively fast to react after 2 hours, and reaction speed obviously slows down, and reacts to be tending towards complete in 4 hours.Along with the carrying out of polymerisation, the viscosity of reaction system slowly increases, and obtains the thickness transparency liquid at last.In product, add alkali, as NaOH, potassium hydroxide, ammoniacal liquor etc., the pH value of product is transferred to 3.5-4.5, add the preservative benzoic acid of product 0.2-0.4% again, promptly make water soluble quarternary copolymer softener of the present invention.
Adopt quarternary copolymerized system in the present invention, the product of generation is a quadripolymer, has only two membered copolymers and terpolymer in the market.Application result shows: the effect of terpolymer is better than the bipolymer, and quadripolymer of the present invention increases than the properties of product of terpolymer again.
Embodiment one
In the enamel reactor that has agitator and heating jacket, drop into the deionized water of 43.0Kg, acrylamide propyl trimethyl ammonium chloride in the cationic monomer of adding 3.0Kg, 1.5Kg the acrylic acid in the anionic monomer, 1.0Kg the ethyl acrylate in the non-ionic monomer, 1.5Kg acrylamide, mix, add the potassium peroxydisulfate initator of 0.1Kg again, carry out the chain initiated polymerization.38 ± 2 ℃ of control polymeric reaction temperatures.Polymerization reaction time 8 hours obtains the thickness transparency liquid.Add 1.5Kg NaOH and the Ph value is transferred to about 4.0, add the benzoic acid of 0.1Kg again, promptly make the softener of water soluble quarternary copolymer.
Embodiment two
In the enamel reactor that has agitator and heating jacket, drop into the deionized water of 37.5Kg, acrylic acid trimethylamine ethyl ester ammonium chloride in the cationic monomer of adding 5.0Kg, 4.0Kg the methacrylic acid in the anionic monomer, 1.5Kg the methyl acrylate in the non-ionic monomer, the 2.0Kg acrylamide.Mix, add the benzoyl peroxide of 0.075Kg again, carry out the chain initiated polymerization.68 ± 2 ℃ of control polymeric reaction temperatures.Polymerization reaction time 5 hours obtains the thickness transparency liquid.In product, add ammoniacal liquor 2.1Kg again, the pH value of product is transferred to 3.8, add the benzoic acid of 0.22Kg again, promptly make the softener of water soluble quarternary copolymer.
Claims (3)
1, a kind of preparation method of water soluble quarternary copolymer softener, it is characterized in that at percentage by weight be in the deionized water of 72-88%, the acrylic acid trimethylamine ethyl ester ammonium chloride or the acrylamide propyl trimethyl ammonium chloride that add 5-12%, the acrylic or methacrylic acid of 3-10%, the methyl acrylate of 2-5% or ethyl acrylate, the 2-5% acrylamide, mix, the peroxide or the persulfuric acid salt initator that add above-mentioned total amount 0.1-0.3%, carry out polymerisation, reaction temperature 35-70 ℃, reaction time 4-8 hour, in product, add alkali, the pH of product is transferred to 3.5-4.5, add the preservative benzoic acid of product weight 0.2-0.4% again.
2, the preparation method of water soluble quarternary copolymer softener according to claim 1 is characterized in that described initator is potassium peroxydisulfate or benzoyl peroxide.
3, the preparation method of water soluble quarternary copolymer softener according to claim 1 is characterized in that described alkali is NaOH or potassium hydroxide or ammoniacal liquor.
