按生产的方式分类可以分为:
Classified according to the mode of production can be divided into:
1、 乳液聚合 是通过单体、 引发剂及蒸馏水一起反应聚合而成,一般所成树脂为固体含量为50%的乳液,是含有50%左右水的乳胶溶液。合成出来的乳液,一般都是乳白泛滥(丁达尔现象), 玻璃化温度根据FOX公式设计。故该类型的乳液分子量大,但是固含一般是40%-50%。生产工业要求控制精确,由于使用水做溶剂,环保型乳液。
1, emulsion polymerization is through monomer, initiator and distilled water reaction polymerization, usually made of resin for the solid content of 50% emulsion, is about 50% of water emulsion solution. The synthetic emulsions are generally milky and milky, and the glass temperature is designed according to the FOX formula. Therefore, the type of emulsion has a large molecular weight, but the solid content is generally 40%-50%. The production industry requires precise control over the use of water as a solvent and environmentally friendly emulsions.
2、悬浮聚合 是一种较为复杂的生产工艺,是做为生产固体树脂而采用的一种方法。固体丙烯酸树脂,采用了带甲基的丙烯酸酯下去反应聚合。带甲基的丙烯酸酯一般都是带有一定的官能团,其在反应滏中聚合反应不易控制,容易发粘而至爆锅。流程是将单体、引发剂、 助剂投入反应斧中然后放入蒸馏水反应!在一定时间和温度反应后再水洗,然后再烘干,过滤等。其产品的生产控制较为严格。如在中间的哪一个环节做得不到位,其出来的产品就会有一定的影响。主要是体现在颜色上面和分子量的差别。
2, suspension polymerization is a kind of complex production process, it is a method for producing solid resin. The solid acrylic resin is polymerized with methyl acrylate. With methyl acrylate are generally with certain functional groups in the reaction in Fu polymerization is not easy to control, easy sticky to fry. The process involves putting monomers, initiators, and additives into the reaction axe and then placing it in distilled water! After a certain period of time and temperature response, then wash, and then drying, filtering, etc.. Production control of its products is more stringent. As in the middle of which link is not in place, its products will have a certain impact. Mainly reflected in the color above and molecular weight difference.
3、本体聚合 是一种效率较高的生产工艺。过程是将原料放到一种特殊塑料薄膜中,然后反应成结块状,拿出粉碎,再过滤而成,该种方法生产的固体丙烯酸树脂其纯度是所有生产法中可以最高的,产品稳定性也是最好的,同时其缺点也是满多。用本体聚合而成的丙烯酸树脂对于溶剂的溶解性不强,有时相同的单体相同的配比用悬浮聚合要难溶解好几倍,而且颜料的分散性也不如悬浮聚合的丙烯酸树脂。
3, bulk polymerization is a highly efficient production process. Is the process of material into a special plastic film, and then reacted to caking, crushing and filtering out, then, solid acrylic resin production method and its purity is all production method can be the highest, the stability of the product is the best, but its shortcomings are full of many. Made by bulk polymerization of acrylic resin for solvent solubility is not strong, sometimes the same same monomer ratio by suspension polymerization to dissolve several times, and pigment dispersion than suspension polymerization of acrylic resin.
4、其它聚合方法 溶剂法反应,反应时经溶剂一起下去做中介物质,经反应釜好后再脱溶剂。
4, other polymerization method, solvent method, reaction, through the solvent down together to do intermediary material, after the reaction kettle is good, then take off the solvent.
热固性丙烯酸树脂
Thermosetting acrylic resin
以 丙烯酸系 单体( 丙烯酸甲酯、 丙烯酸乙酯、 丙烯酸正丁酯和 甲基丙烯酸甲酯、 甲基丙烯酸正丁酯等)为基本成分,经 交联成网络结构的不溶不熔丙烯酸系 聚合物。
The acrylic monomer (methyl acrylate, ethyl acrylate, butyl acrylate and methyl methacrylate, butyl acrylate as basic components, etc.) into insoluble and infusible acrylic crosslinked polymer network structure.
除具有丙烯酸树脂的一般性能以外, 耐热性、 耐水性、 耐溶剂性,耐磨耐划性更优良。有本体浇铸造 材料、溶液型、乳液型、水基型多种形态。
In addition to the general properties of acrylic resin, heat resistance, water resistance, solvent resistance, abrasion resistance, better resistance to scratch. There are many kinds of casting material, solution type, emulsion type and water base type.
