我们将单体按配方设计的量与表面活性剂及水进行预乳化后抽入高位槽,引发剂用水溶解后抽入另一高位槽。两者同时以滴加的方式进入反应釜进行聚合反应。反应温度控制在70-85度,控制滴加速度,使反应物料在3—3.5h滴完。最后保温反应1-1。5h,使反应完全。然后冷却,用氨水将乳液PH值调至7-8。这是乳液的制法。
We will be the amount of monomer according to the formula design and surfactant and water pumped in high slot, after pre emulsified initiator water dissolves into another high slot. Both at the same time to add the way into the polymerization reaction kettle. Reaction temperature control in 70-85 degrees, dropping speed control, the reaction material in 3-3.5 h drip off. The final thermal reaction 1-1. 5 h, the reaction completely. And then cooling, the emulsion with ammonia PH value to 7-8. This is the emulsion was prepared.
丙烯酸涂料的制法:
Acrylic coating was prepared:
本防水涂料的植被采用常规的涂料制备方法。将水、分散剂、消泡剂、颜料、填料及其他助剂按配方称量后投入高速分散釜,同时加入上述制备的丙烯酸共聚乳液,经充分搅拌后即得防水涂料。可采用的颜料、填料有二氧化钛、滑石粉、重质碳酸钙、云母粉、瓷土、氧化锌、沉淀硫酸钡等。
The waterproof coating of vegetation with conventional preparation methods of coatings. Water, dispersing agent, defoamer, pigment, filler and other additives according to the formula into the high-speed dispersing kettle after weighing, and to join the preparation of acrylate copolymer emulsion, after fully mixing the quick waterproof coating. Can use of pigment, filler, mica titanium dioxide, talcum powder, calcium carbonate powder, China clay, zinc oxide, precipitated barium sulfate, etc.
说明:
Description:
丙烯酸酯防水涂料是由丙烯酸酯共聚乳液为成膜物质再加以各种颜料、填料而制成的一种水性可调色的、橡胶型的涂料。其特点是,涂膜干燥后能形成连续性的涂层,涂层具有良好的延伸率及断裂强度,耐酸、耐碱性好,耐候性优异、施工方便、无环境污染,作为屋面防水是一种较理想的材料。
Acrylic waterproof coating is made up of acrylate copolymer emulsion as film forming material to all kinds of pigments, fillers and a water can be made of color mixing, rubber type of coating. Its characteristic is that after coating is dry to form a continuous coating, the coating has good elongation and fracture strength, good acid and alkali resistance, excellent weatherability, construction is convenient, no environmental pollution, as the roof waterproof is a kind of ideal material.
