Description
Technical field
The invention belongs to technical field of coatings, and in particular to one kind can convert into the flexible waterproof coating of deformation.
Background technique
In household building, connect between building splice wall connecting between boundary gap and cabinet and construction wall
Gap is usually both needed to be filled using water-repellent paint and be coated, to form one layer of waterproof paint layer, gap is completely enclosed, and prevents water
Body is infiltrated between cabinet and wall, to prevent cabinet or wall from meeting water for a long time and mildew occurs and rots, but existing application
It is easy desiccation after a period of use in the coating of such seal applications to be detached from, needs periodically to repair repeatedly, mainly due to coating
Itself is excessively rigid in the paint layer that adhesive force is low and coating is formed of body surface, and paint layer is formed between gap bending, without
It is smooth paint layer, the stress of paint layer everywhere is different, causes paint layer vulnerable to power breakage, the service life of paint layer is short, this is just needed
The coating of this kind of purposes has flexibility, has flexible waterproof coating on the market, and the paint layer of formation has certain flexibility, compared to
Conventional water-repellent paint, the paint layer service life that full-filling is formed in gap is longer, but is only capable of applying on cement wall, paint layer
The long-term soaked blistering that can soften, or generate the phenomenon that lacquer painting whitens.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of flexible waterproof coating that can convert into deformation.
The technical scheme adopted by the invention to achieve the purpose is as follows:

~35 parts, 18~25 parts of coupling agent, 90~120 parts of silica flour, 100~150 parts of deionized water.
It further illustrates, the special acrylic emulsion is branch acrylic emulsion.
It further illustrates, the dispersing agent uses one of fatty alcohol polyoxyethylene ether, oxidized polyethylene wax.
It further illustrates, the waterproofing agent uses water-based organic silicon waterproof agent.
It further illustrates, the thickener is trans- acrylic emulsion thickener.
It further illustrates, the coalescing agent uses one of propylene glycol phenylate, Lauryl Alcohol ester.
It further illustrates, the coupling agent is one of Silane coupling agent KH550, KH560, KH570, KH792
Or it is two or more.
It further illustrates, the particle diameter distribution of the silica flour is in 800~1000 mesh.
The above-mentioned flexible waterproof coating for converting into deformation is prepared by following implementation steps:
S1. addition deionized water, fatty alcohol polyoxyethylene ether are uniformly mixed in Scattered Kettle, and quartz is then added
Powder, high-speed stirred 10min keep constant-speed mixing, are slowly added to special acrylic emulsion, are stirred well to uniformly；
S2. successively into reaction kettle put into waterproofing agent, defoaming agent, thickener, propylene glycol phenylate, KH550 silane coupling agent,
KH560 silane coupling agent is stirred to uniform, 800 meshes excessively, i.e. completion preparation under high speed agitation.
Wherein, the present invention uses matrix of the special acrylic emulsion as coating, then is evenly distributed with waterproofing agent, coupling
Agent, silica flour, under the facilitation of coalescing agent solidify crosslinking, the paint layer densification impunctate of formation and have well it is soft
Property.
Compared with prior art, the beneficial effects of the present invention are:
The paint layer that existing flexible waterproof coating is formed can not convert into repeatedly, and coating can only consolidate and be adhered to cement and build
It builds surface, and the coating in the present invention has good viscosity, can consolidate and be adhered to textile fabric and wooden, cement base build
Surface is built, the paint layer to be formed is fully cured with extremely strong flexibility, can convert into repeatedly repeatedly, and there is good waterproofness, paint
Layer be immersed in water environment six months it is without exception, no generation is whitened and foaming phenomena.
