Description
所属技术领域
本发明涉及一种轻质墙板，特别涉及一种连续法生产的轻质墙板。
背景技术
目前，市面上的轻质墙板，即非承重墙板，都是间断式的浇铸法生产，国内外都没有连续化生产的报导，此法的最大缺点除生产率低下，不能满足建筑行业的速度要求外，其耐水性，特别是以石膏为主料的轻质墙板的耐水性和机械强度都很差。直到目前为止，我国还未定出石膏空心板条的耐水性标准。
发明内容
为了克服间断式浇铸的轻质墙板的缺点，本发明的目的在于提供一种连续化生产的轻质墙板。其优点是生产率可大提高，产品质量稳定，机械强度和耐水性好的轻质墙板。本发明技术方案如下：
(1)轻质墙板的配方(以下均以重量份计)
石膏： 38-42
膨胀珍珠岩、密度为40-80公斤/米3： 4-6
猪毛： 0.4-0.6
水： 15-23
硅溶胶： 1-2
(2)连续法生产轻质墙板的专用机为本发明人发明的，中国实用新型号00236514.6连续化生产轻质墙板的挤压成型机，挤出压力为0.6-1.0兆帕。
上述配方中的石膏是一般建筑用就可。对于膨胀珍珠岩，则要求其密度为40-80公斤/米3，若密度低于40公斤/米3，则墙板的机械强度变低，若密度高于80公斤/米3，则墙板的隔热性差。猪毛要求干净就可，本配方的主要特征是石膏与水的重量份比为(38-42)∶(15-23)，即其比值约0.4-0.55，若小于0.4，则水不能满足石膏固化对水的要求量；若比值大于0.55，则墙板的隔热性差，因此，水的加入量越小越好，直到满足石膏固化时所需的水量为止。加入猪毛可提高其握钉力，它是一种动物性纤维，是天然的绿色物质。而目前市面上的间断式生产墙板，除加入石膏、珍珠岩(无密度要求)和水外，还要加入减水剂、反应剂等化学物质，是属于非绿色物质，故所制出的墙板是谈不上环保要求的。至于硅溶胶的加入是提高耐水性的和强度的配剂。
上述所用的专用挤压成型机，是本发明人的实用新型专利产品，其工作压力要求在0.4-1.0兆帕，若压力小于0.4兆帕，则墙板的耐水性差，若压力大于1.0兆帕，则墙板偏重。因此，控制此成型压力是极为重要的。
综合上述情况，本发明的特点在于配方中石膏和水比，对膨胀珍珠岩的要求，加入猪毛，不用减水剂和反应剂以及采用加压成型法这五个特征。
本发明的有益效果是，第一、墙板的质量高；第二、原料都是天然产品，故该墙板是属于绿色产品。
具体实施方式例1 将石膏38公斤，膨胀珍珠岩(密度为40公斤/米3)4公斤，猪毛0.4
公斤，水15公斤，硅溶胶1公斤，投入通用的混合器内混合均匀，然
后连续流入实用新型号为00236514.6的挤压成型机内，在0.6兆帕的
压力下挤压成型，产品的性能测试列于表1中。例2 将石膏42公斤，膨胀珍珠岩(密度为80公斤/米3)6公斤，猪毛0.6
公斤，水23公斤，硅溶胶2公斤，投入通用的混合器内混合均匀，然
后连续流入实用新型号为00236514.6的挤压成型机内，在1.0兆帕的
压力下挤压成型，产品的性能测试也列于表1中。

注：目前轻质墙板的耐水性国家还没有标准，暂用软化系数来反映，系数值越高耐水性越好。
