Description

一种功能性多孔陶瓷踏脚砖
技术领域
本专利涉及陶瓷制品技术领域，具体来说就是一种吸水性强的功能性多孔陶瓷踏脚砖，同时提供这种功能性多孔陶瓷踏脚砖的制备方法。
背景技术
传统的布艺、塑料类脚垫涉及化工、纺织、印染等行业，在制作的过程中易产生污染，而且使用后的废物也会对环境产生污染。同时传统的布艺、塑料类脚垫在使用过程中易滋生细菌、发霉，影响人体健康，且不易清洗。由于传统的布艺、塑料类脚垫并不具备良好的吸水性，长时间使用会产生刺鼻的味道。
目前市场上流行的一些硅藻土脚垫，如中国专利申请2015105692893公开的“一种吸水性强的抗菌陶瓷制品及其制备方法”，抗菌陶瓷制品的原料质量百分比组成为：200-300目的硅藻土30-60%，300-500目的粘土18-30%，200-300目的氧化钙5-15%，200-300目的氧化铝15-30%。其是采用低温粘结剂粘结，为了达到踩踏强度，必须加入较多的粘结剂，导致材料的吸水孔数量大大减少，因此材料的吸水性较差；且该类脚垫表面强度较差，在清洗时容易脱落，影响外观和使用寿命。
发明内容
本发明的目的在于制备出一种全新的功能性多孔陶瓷踏脚砖，拼装成脚垫，该产品能够迅速吸干人体皮肤表面的水分，给人以干爽、舒适的生活，并起到防滑的作用，而且表面强度高，使用寿命长，同时具有轻便、不易滋生细菌、不易发霉和易清洗等优点。
为实现本发明目的，提供了以下技术方案：一种功能性多孔陶瓷踏脚砖，包括坯体和坯体表面的陶瓷装饰料，其特征在于：
坯体的各组份原料的重量配比为：
硅藻土 10μm-100μm 30-70份
苏州土 10μm-40μm 10-40份
硅微粉 10μm-40μm 5-10份
长石 10μm-40μm 5-10份
碳酸钙 10μm-40μm 5-15份
上述组份重量为100份，以此为基准，外加：
聚乙烯醇 工业级 0.5-2份
水 80-120份；
陶瓷装饰料的组分原料的重量配比为：
长石 10μm-40μm 40-80份
苏州土 10μm-40μm 10-40份
碳酸钙 10μm-40μm 5-15份
硅微粉 10μm-40μm 5-10份
上述组份重量为100份，以此为基准，外加：
陶瓷色料 1-5份
水 100-120；
制备方法是分别将坯体、陶瓷装饰料的各组份按配比球磨混合成浆料，将坯体浆料喷雾造粒，陈腐后制成坯体，再在坯体上喷涂陶瓷装饰料浆料，烘干后烧成。
制备坯体浆料时，将坯体各组份球磨混合10-20h，球磨完后对浆料进行除铁，过100目筛后放入搅拌池备用。
进一步，制备坯体时，采用压力泵将坯体浆料输送到喷雾造粒塔中，喷雾造粒塔的进口温度控制在350-380℃，出口温度控制在140-160℃，造粒好的料过40-60目振动筛，装袋，然后陈腐24-48小时以上方可使用。
作为优选，制备坯体时，采用液压机成型坯体，成型压力为7-15MPa。
作为优选，陶瓷装饰料的各组分混合球磨制备浆料，混合时间为24-48h，过180-200目筛后，采用喷涂的方式将浆料喷涂到踏脚砖坯体表面，然后放在烘箱内恒温40-60℃下干燥10min以上。
作为优选，产品最后的烧成，烧成时间为15-24h，烧成温度控制在1150-1250℃之间。
配方中的硅藻土，其自带的细孔能提供很好的吸水性能；碳酸钙的加入，在烧成时产生一部分气体在坯体内部形成气孔；喷雾造粒料相互堆积，在成型时用相对低的压力成型，无法压碎又能提供一部分堆积孔。因此，采用此类配方、工艺制备出的陶瓷踏脚砖具有非常高的吸水率，拼装成脚垫后性能上远大于市场上的硅藻土脚垫。
在脚垫的坯体上喷涂不同颜色的陶瓷装饰料，陶瓷装饰料不仅可以使脚垫更加美观，同时它使得脚垫表面具有很好的强度，使得产品更加耐脏，且清洗的时候可直接用毛刷清洗，不易脱落，使产品更加耐用。
本发明有益效果：本发明以硅藻土为主要原料配比其它陶瓷料，采用陶瓷的制备方法，制备出新型的功能性多孔陶瓷踏脚砖，然后拼装成陶瓷脚垫，其具备吸湿、防滑、轻便、不易滋生细菌、不易发霉、易清洗、污染小且强度好等优点。和传统的布艺、塑料类脚垫相比，是一种全新的体验，随着该类产品的不断发展，必将带来居家生活的变革，也必将推动相关行业的发展。同时多孔陶瓷踏脚砖在制造过程不会污染环境，且其废弃物可以重复利用。
