Washing-free washing stone and preparation method thereof

The invention discloses a washing-free washing stone and a preparation method thereof. The washing-free washing stone comprises the following raw materials in parts by weight: 110-125 parts of water, 2-4 parts of cellulose, 2-3 parts of bentonite, 2-3 parts of a bactericide, 1-2 parts of a pH regulator, 1-2 parts of a defoaming agent, 140-150 parts of an organosilicon emulsion, 4-6 parts of ethylene glycol, 6-9 parts of a C-12 coalescing agent, 3-5 parts of an associative thickener and 700-750 parts of gravel. The problems that traditional cement-based washed stone is large in dosage, difficult to construct and prone to weathering and cracking are solved. 本发明公开了一种免水洗的水洗石及其制备方法，包括以下重量份数的原料：110～125份水、2～4份纤维素、2～3份膨润土、2～3份杀菌剂、1～2份PH调节剂、1～2份消泡剂、140～150份有机硅乳液、4～6份乙二醇、6～9份C-12成膜助剂、3～5份缔合型增稠剂、700～750份砂砾；本发明解决了传统水泥基水洗石用量大、施工困难、易风化开裂的问题。
