Description

A kind of production technology and construction method of polymer mortar Water-proof liquid (breast)
First, technical field
The present invention relates to a kind of production technology and construction method of polymer mortar Water-proof liquid (breast), in existing waterproof material In classification, it may act as additive and be added in concrete to play a part of self waterproofing, and can add in and smear base in mortar Layer plays a part of outer waterproof.In the practice of market more than ten years, huge social benefit is showed in building field.
2nd, background technology
" natural person is natural ", this is the facade lighting of 21st century;It is one large-scale non-in the world today Military force revolution has also fed through to building trade." revolution of building ", a loud slogan are proposed out.It is environment protection architecture, green Color is built, and solar building comes into being.Especially just it is being suitble to the waterproof of current external wall the application of this product
It mentions building and just associates 5 percent waterproof material for accounting for building total cost (developed country is 8%).In State increasingly payes attention to waterproof with people, and waterproof cost is also gradually improving.
" innovation of material, the revolution of building ", in other words " innovation of waterproof material, the revolution of buildings waterproof ".Designing institute Thinking is created, and construction unit considers cost, and building enterprise's requirement construction is simple, these, are exactly the purpose of the present invention.
3rd, invention content
1st, Products:The object of the present invention is to provide a kind of Polymeric water repellent materials.Its active ingredient is with organic matter Coconut oil or palm oil add in other plurality of active ingredients inorganic compounds as main body object and regroup under temperature constant state instead A kind of new high molecular polymer should be generated.Its main feature is that the principle i.e. coconut oil macromolecular that oil blocks water, which is utilized, blocks small molecule The principle of water carrys out waterproof;The a variety of inanimate matters such as villaumite additionally incorporated, sulfate add in aluminium, calcium, iron plasma and its alkalization Object, it is all the substance of waterproof of blocking water that the carboxylic of generation, which closes object,.
2nd, the process of production:1. by a kind of organic matter coconut oil and a variety of inanimate matters under certain thermostatic control, by holding It is continuous to be stirred continuously, it sequentially adds, multiple reactive polymeric, the liquid or breast of a kind of polymer is finally obtained, according to water additive amount How much different polymeric liquid and polymer breast are obtained.In the case of certain coconut oil and a variety of inanimate matters, during reaction Polymeric liquid is obtained in the case of adding in a certain amount of water mostly, polymer breast is obtained in the case of adding in a certain amount of water less.
3rd, the waterproof principle:The structure of cement during with changing hydration reaction in cement mortar is mixed, being made between cement particle sum aggregate material Formation is turned one's coat adsorption layer, while produces insoluble substance filling capillary porosity duct, avoids the infiltration because being generated between material molecule The hydraulic pressure external carbuncle generated under property internal stress and external effect, is allowed to impermeable, so as to reach water proof anti-seepage, moisture-proof, leak stopping Purpose.
