本发明属于保温砂浆生产技术领域，尤其是涉及一种生产保温砂浆的工艺方法。
保温砂浆是以各种轻质材料为骨料，以水泥为胶凝料，掺和一些改性添加剂，经生产企业搅拌混合而制成的一种预拌干粉砂浆。用于构筑建筑表面保温层的一种建筑材料。无机保温砂浆材料保温系统防火不燃烧。可广泛用于密集型住宅、公共建筑、大型公共场所、易燃易爆场所、对防火要求严格场所。还可作为放火隔离带施工，提高建筑防火标准。
然而目前的保温砂浆在生产时，主要是通过将水泥与纤维素醚等原料放置在搅拌机中经三次搅拌制得，一方面由于保温砂浆在搅拌时多是沿一个方向进行搅拌，容易在搅拌过程中使得一些干粉料在搅拌初被拨到搅拌罐内外围，导致保温砂浆最终搅拌均匀度较差，另一方面由于保温砂浆在生产过程中均采用传统材料制备，无法实现对工业废弃物的再利用，同时由于采用传统材料所制备的保温砂浆功能有所局限，无法满足资源日益短缺情况下保温砂浆的生产需求。
发明内容
有鉴于此，本发明旨在提出一种生产保温砂浆的工艺方法，该保温砂浆通过采用粉碎研磨以及正反搅拌的方式来对保温砂浆进行制备，有效确保了保温砂浆在制备后的颗粒的均匀度，保证保温砂浆后期的使用质量，同时采用矿渣代替部分水泥作为胶凝材料，不仅实现了工业废弃物废物的再利用， 提高了资源的利用率，而且矿渣本身具由较高的潜在活性，大大提高了保温砂浆在使用后的强度，此外采用再生聚苯颗粒完全代替砂作为砂浆的轻质骨料，大大增加拉保温砂浆在后期使用时的保温性能以及抗腐蚀性能，满足资源日益短缺情况下保温砂浆的生产需求，再者采用聚丙烯纤维来增加保温砂浆的韧性，有效增加了保温砂浆的防水抗渗性能，从而使得保温砂浆的使用寿命得到提高。
为达到上述目的，本发明的技术方案是这样实现的：
一种生产保温砂浆的工艺方法，该保温砂浆由如下百分含量的原料制成：水泥和矿渣混合物70％-80％，再生聚苯颗粒5％-10％,可再分散胶粉2-3％，纤维素醚0.5％-1％，聚丙烯纤维6％-22.5％。
进一步的，水泥和矿渣混合物中矿渣占水泥用量的15％-45％，选用矿渣代部分水泥作为保温砂浆的胶凝材料，能够有效减小水泥用量，有利于工业废弃物的再利用，同时矿渣自身具有很大的潜在活性，掺加在保温砂浆中能对其后期强度增长做出贡献。
进一步的，再生聚苯颗粒的优选添加用量为7-8Kg/L，聚丙烯纤维的优选添加用量为0.3g/L，选用再生聚苯颗粒完全替代砂作为砂浆的轻骨料，能够有效利用其颗粒表面形态不规则、导热系数小、化学稳定性好、抗腐蚀等特点，全面增加砂浆的施工和易性、热工性、抗腐蚀等性能，采取聚丙烯纤维增韧的措施，增大保温砂浆韧性与抗裂性能，有效分散了保温砂浆原始裂纹的内部应力集中现象，提高了保温砂浆的防水抗渗性能。
进一步的，可再分散胶粉的优选用量为2.5％，纤维素醚的优选用量为0.7％-0.8％，选用可再分散胶粉和纤维素醚两种聚合物，与水泥等无机胶凝材料复合，能够通过有机聚合物的表面改性、粘结、保水等效应，改善再生聚苯颗粒的表面亲水性，增加了保温浆料的内聚性，提高保温浆料的保水性，使保温浆料的施工和易性能更加优良。

进一步的，该保温砂浆在使用方法如下：使用时将该保温砂浆与水按照5:4的比例进行均匀混合，然后将混合后的保温砂浆料涂抹在相应的墙体上，涂膜厚度以86-88mm为宜。
相对于现有技术，本发明所述的保温砂浆具有以下优势：
