Abstract
An elastic acrylate emulsion as building paint is prepared from deionized water (10-15 wt.%), methylacrylate (15-25), acrylate (25-30), methylacrylic acid (3-5), composite emulsifier (3.5-5.5), potassium persulfide (0.4-0.6) and ammonia water (20-30) through copolymerization. Its advantages are high elasticity, low vitrification temp (0 deg.C) and good water-proofing nature.
Description
Technical field
The present invention relates to building coating with the synthetic field of emulsion, especially a kind of elastic acrylate emulsion synthetic.
Background technology
Along with improving constantly of science and technology development and building coating performance, emulsion is as a kind of requisite component, in the production of many polymkeric substance such as coating, cakingagent, flocculation agent, synthetic rubber, impact-resistant copolymerized thing etc. is synthetic, become a very important part.And, make it in nearly 100 years historical progress based on itself having many good characteristics, become a foundation stone in the chemical industry gradually.And at this wherein, acrylic emulsion is because the monomeric species of its raw material is various, range of product is many and have good integrated application performance, make its this field development rapidly relatively always.
Self-evident, the application of acrylic emulsion in building trade also is more and more important, and along with the continuous enhancing of people's Environmental awareness, water milk type coating has become important developing direction of coatings industry.How to improve the performance of water milk type coating, one of them key factor is exactly the problem of emulsion, and there are defectives such as film-forming temperature is higher, water tolerance is bad in traditional emulsion, and has limited its application in water milk type coating greatly.
Summary of the invention
In order fundamentally to overcome the defective of the water milk type coating aspect of performance that is caused owing to the emulsion factor, the invention discloses a kind of prescription of elastic acrylate emulsion, this formulation selection suitable soft, hard monomer, added cross-linking monomer, used anionic emulsifier and nonionic emulsifying agent is composite, thereby guaranteed that this synthetic emulsion has higher elasticity (elastic extension reaches 600%), lower second-order transition temperature (0 ℃) and water tolerance preferably can be widely used in the preparation process of building coating.
Elastic acrylate emulsion of the present invention is formed by several component copolymerization, and its prescription comprises:
Deionized water 10-15%,
Methacrylic ester 15-25%,
Acrylate 25-30%,
Methacrylic acid 3-5%,
Composite emulsifier 3.5-5.5%,
Potassium Persulphate 0.4-0.6%,
Ammoniacal liquor 20-30%.
As not having specified otherwise, per-cent all is weight percent in this specification sheets.
Wherein: described methacrylic ester is a soft monomer, and this soft monomer also can be methyl methacrylate, Jia Jibingxisuanyizhi.
Acrylate is a hard monomer, and certainly, this hard monomer also can be butyl acrylate, ethyl propenoate.
Methacrylic acid is a cross-linking monomer, and this cross-linking monomer also can be vinylformic acid, acrylamide.
Compound emulsifying agent mainly is that anionic emulsifier and nonionic emulsifying agent are composite, wherein, and nonionic emulsifying agent: anionic emulsifier=1: (1～2).
Potassium Persulphate is an initiator.
In this elastic acrylate emulsion of preparation, at first deionized water and emulsifying agent are added reactor in proportion, heated and stirred, temperature is controlled at 60-70 ℃, after special emulsifying agent dissolves fully, add 1/5 mix monomer again and carry out pre-emulsification, the time is controlled at 0.5h, temperature is about 50 ℃, and what finally obtain in the reactor is uniform emulsion; Be warming up to 65-70 ℃ then, initiator solution with 1/4 adds (initiator is mixed with 5% the aqueous solution in advance) wherein, at 80 ± 2 ℃ of following stirring reactions, then in 2.5-3h, be added drop-wise in the reactor residual monomer and initiator solution in batches, feed rate depends on the backflow situation, when to the last a batch of material adds afterreaction soon near end, be warming up to 85-90 ℃, insulation 0.5-1h.Vacuumize at last and remove residual monomer, lower the temperature 40-50 ℃, behind ammoniacal liquor adjusting pH to 7-8, filter discharging.
Compared with prior art, selected starting material in the present invention's prescription, except suitable soft, outside the hard monomer proportioning, also added cross-linking monomer, used anionic emulsifier and nonionic emulsifying agent is composite, thereby guaranteed that this synthetic emulsion has higher elasticity (elastic extension reaches 600%), higher intensity, lower second-order transition temperature (0 ℃) and water tolerance preferably, and stability is also fine, can be widely used in the preparation process of building coating, such as external wall system, the waterproof paint system especially needs emulsion to have in the lower application system of elasticity and second-order transition temperature.
