本发明公开了一种乳液混拼交联软瓷及其制备方法，该制备方法是将5~15份不同玻璃化温度的羧基型水性软硬乳液、1~5份交联剂、20~40份钙粉、30~50份石英砂、0.5~5份粗纤维、5~15份水按照比例混合，50~100oC烘烤2~5h制备得到乳液混拼交联软瓷。本发明采用乳液混拼技术制备的软瓷综合了两种乳液的特性，赋予其一定硬度的同时，表现出优异的柔韧性；另一方面，在配方体系中引入羧基交联剂，实现软硬乳液混拼交联形成互穿网络结构，提高分子内聚力，解决水性乳液热粘冷脆的技术难题。该发明制备简单，成本低廉，适于工业化生产。以此方法生产的软瓷具有优良的柔韧性、高硬度及优异的耐候性能。

The preparation method comprises the following steps: mixing 5-15 parts of carboxyl type water-based soft and hard emulsions with different glass transition temperatures, 1-5 parts of a cross-linking agent, 20-40 parts of calcium powder, 30-50 parts of quartz sand, 0.5-5 parts of crude fibers and 5-15 parts of water in proportion, and baking at 50-100 DEG C for 2-5 hours to obtain the emulsion mixed cross-linked soft porcelain. The soft porcelain prepared by adopting an emulsion mixing technology integrates the characteristics of two emulsions, and shows excellent flexibility while being endowed with certain hardness; on the other hand, a carboxyl crosslinking agent is introduced into a formula system, so that soft and hard emulsions are mixed and crosslinked to form an interpenetrating network structure, the molecular cohesion is improved, and the technical problem that the water-based emulsion is sticky in hot and crisp in cold is solved. The preparation method is simple, low in cost and suitable for industrial production. The soft porcelain produced by the method has excellent flexibility, high hardness and excellent weather resistance.
