Description

一种猫砂添加剂及其制备方法和应用 技术领域
本申请属于宠物用品领域，具体涉及一种猫砂添加剂及其制备方法和应用，尤其涉及一种密度低的猫砂添加剂及其制备方法和应用。
背景技术
对于猫砂添加剂的制备方法而言，传统制粒方法一般通过将液体、粉末基底和粘合剂混合后挤压成型，后经过加热快速烘干。这样的方法通常需要的液体量较大，面对昂贵或难以稀释的液态有效成分操作不便，成本也大大提升。同时传统的挤压制粒法使用瓜尔豆胶作为粘合剂，通过挤压与热成型工艺进行制备，易导致颗粒密度过大，而颗粒密度过大又会使得添加剂沉入猫砂下部，失去效果，且通常需要添加大量粘合剂，从而颗粒的吸水性较差，吸水速率缓慢且制成后的颗粒难以快速溶于水。并且传统制粒的干燥方法多为烘干，而高温容易导致液体有效成分中热敏物质发生变性或反应，影响猫砂添加剂的效果。
因此，如何提供一种密度低、吸水性好、制备简单、成本低的猫砂添加剂的制备方法，成为了亟待解决的问题。
