Abstract
The invention discloses a reactive polymer cement waterproof coating that contains an organic component, an inorganic component and water of which the weight ratio is 1:1-2:0.6-0.9, wherein the organic component is an end NCO base prepolymer obtained from the reaction of vacuum dehydrated polyether polyol with polyisocyanates; and the inorganic component is cement and inorganic filler and the mixture of the two. The product is non-toxic, free of pollution and environment-friendly. The coating has excellent mechanical property and chemical property, as well as excellent waterproof property. The coating solidifies in reaction, has low requirement on construction environment, allows construction on a damp base surface without visible water, and is good in resistance to low temperature and water, free of swelling and applicable to underground waterproof engineering.
Description
Technical field:
The present invention relates to a kind of reactive polymer cement waterproofing coating that is applied to underground project waterproof.
Background technology:
It is that the last century late nineteen eighties begins to research and develop that JS films in China, and there is minority producer the early 1990s with launch products.Beijing is the place of origin of JS technology, and to middle nineteen nineties, factory few in number mainly concentrates on Beijing.Early stage JS films because defective is more, and particularly aqueous waterproofing paint does not solve the water tolerance problem, and the JS reasons such as meeting water suction swelling of filming has run into very big difficulty on promoting.Film " Technical code for water proof in underground engineering " behind the product appearance several years, " acceptance specification " of JS all filmed JS for a long time and kept outside of the door.Along with JS is coated with the development of membrane technique and country to the improving constantly of living environment, construction environment environmental requirement, also become more and more important for the research of JS polymer cement waterproof paint.
Product in the market mainly is made up of acrylic resin and inorganic powder, this series products has intensity height, no seam, strong, high temperature resistant, the cold construction of cohesive force, characteristics such as nontoxic, but obviously have some defectives in actual application: (1) belongs to volatility curing material, curing speed is slow, long construction period, even not competent solid in the not smooth place that ventilates; (2) can only adopt the mode of scumbling multipass to construct, perhaps not competent solid if thick being coated with can cause cracking, when taking a lot of work, influence quality; (3) poor water resistance after using, water absorption and swelling can occur in underground works, strength degradation influences waterproof effect.And the FJS reactive polymer cement waterproofing coating is a kind of high solids coatings that reacts film-forming, having overcome general water-soluble polymers cementitious coating solidifies by volatilization, construction environment is required height, can not thickly be coated with, easily meets the water-soluble shortcoming that expands, returns breast, possess good impervious ability and whole impervious, water resistance is good, intensity is high, unit elongation is big, and resistance to low temperature is good.And be not subjected to the influence of construction environment, for underground construction provides a kind of novel material.
Summary of the invention:
The purpose of this invention is to provide reactive polymer cement waterproofing coating that a kind of water resistance is good, tensile strength is high, elongation at break is good, curing speed is fast and preparation method thereof, pass through the parameters such as ratio of content, liquid material and the powder of control NCO under study for action, obtain preparing the optimum technology parameter of this reactive polymer cement waterproofing coating, provide Technical Reference for preparing high performance reactive polymer cement waterproofing coating.
The invention provides a kind of reactive polymer cement waterproofing coating, comprise organic constituent and inorganic component, adding entry after during use organic constituent, inorganic component being mixed can solidify, and organic constituent, inorganic component and water with weight ratio count 1: 1～2: 0.6～0.9, wherein:
