Soft porcelain material with high weather resistance
The invention provides a soft porcelain material with high weather resistance and a preparation method thereof, wherein the soft porcelain material comprises the following raw materials by weight: 5-15 parts of Portland cement, 50-70 parts of quartz sand, 10-30 parts of heavy calcium carbonate, 2-8 parts of a modifier, 0.5-6 parts of a flame retardant, and 2-5 parts of a curing agent. The modifier is waterborne polyurethane modified acrylic emulsion, epoxy resin modified acrylic emulsion or a mixture of the waterborne polyurethane modified acrylic emulsion and the epoxy resin modified acrylic emulsion. The invention provides a preparation method of the soft porcelain, wherein the preparation method comprises the three steps of material preparation, mixing and forming. According to the soft porcelain disclosed by the invention, waterborne polyurethane or epoxy resin is introduced into the acrylic emulsion in a chemical copolymerization manner for modification, and through the interaction of the waterborne polyurethane or epoxy resin and the acrylic emulsion, the generated emulsion comprehensively has excellent performances of acrylic acid and waterborne polyurethane/epoxy resin, and the defect that the acrylic emulsion is sticky in hot and crisp in cold is overcome; and the produced soft porcelain is not easy to break, good in elasticity and excellent in weather resistance.
本发明提供了一种具有高耐候性的软瓷材料及其制备方法，原料包含按重量配比的如下组分：硅酸盐水泥5‑15份、石英砂50‑70份、重钙10‑30份、改性剂2‑8份、阻燃剂0.5‑6份、固化剂2‑5份，改性剂为水性聚氨酯改性丙烯酸乳液、环氧树脂改性丙烯酸乳液或两者的混合物，还提供了该软瓷的制备方法，包括备料、混合、成型三个步骤；本发明所述的软瓷，通过化学共聚的方式在丙烯酸乳液中引入水性聚氨酯或环氧树脂进行改性，通过二者的相互作用，使生成的乳液综合兼具有丙烯酸和水性聚氨酯/环氧树脂的优良性能，克服了丙烯酸乳液“热粘冷脆”的缺陷，生产出的软瓷具有不易断裂、弹性好以及优异的耐候性。
