Composite calcium material and preparation process thereof
The invention relates to the technical field of composite calcium, and discloses a composite calcium material. The material comprises the following raw materials in parts by weight: 30 parts of calcium silicate, 10 parts of triphenyl phosphate, 4 parts of talcum powder, 20 parts of glyceryl stearate, 20 parts of sodium thiosulfate, 10 parts of aluminum chloride hexahydrate, 20 parts of tetraethoxysilane, 2 parts of diphenyl p-phenylenediamine, 14 parts of sodium pentachlorophenate, 10 parts of magnesium chloride, 20 parts of a sodium sulfonate aqueous solution, 40 parts of silica sol, 2 partsof a binding agent, 4 parts of an anti-hydration additive and 1 part of an antioxidant additive; the content of sodium sulfonate in the sodium sulfonate aqueous solution is 3wt%, and the silica sol contains 40% of silicon dioxide and 0.1% of sodium chloride. According to the composite calcium material and the preparation process thereof, the breaking strength of the cured composite calcium material can reach 1.2 MPa or above through the sodium thiosulfate. A proper amount of talcum powder is added to reduce the linear shrinkage rate and improve the stability of the material.
本发明涉及复合钙技术领域，且公开了一种复合钙材料，包括以下重量份计的原料：硅酸钙30份、磷酸三苯酯10份、滑石粉4份、硬脂酸甘油酯20份、硫代硫酸钠20份、六水合氯化铝10份、正硅酸乙酯20份、二苯基‑对苯二胺2份、五氯苯酚钠14份、氯化镁10份、磺酸钠水溶液20份、硅溶胶40份、镁质原料30份、钙质原料25份、碳质原料10份、结合剂2份、抗水化添加剂4份、抗氧化添加剂1份，磺酸钠水溶液中磺酸钠的含量为3wt％，硅溶胶含有40％的二氧化硅和0.1％的氯化钠，该复合钙材料及其制备工艺，通过本发明中的硫代硫酸钠可以使固化后的抗折强度达到1.2MPa以上。加入适量的滑石粉可以减小线收缩率，提高材料稳定性。
