Abstract
The utility model relate to construction waterproof coating system adopt a kind of self not glued and can the water-fast spirit of water-proof low molecular material and polyvinyl alcohol (PVA) and acetal glue thereof and not water-proof macromolecule glue product such as Mierocrystalline cellulose and derivative thereof be mixed with main agglutinate, and add natural or artificial mineral's powder stopping composition, be made into thick pulpous state lotion coating, blade coating is on the floating layer of the sand-lime of interior wall or ceiling and other planarizing underlayers, form level and smooth, fine and smooth, bright and clean finish coat as porcelain, have the water resistance of washing nondiscoloration and not playing slurry, can keep the sense of porcelain light quality for a long time.
Description
The invention belongs to a kind of construction waterproof coating.
With the polyvinyl alcohol (PVA) and Mierocrystalline cellulose (CWC) the class water-sol is that the existing multiple commodity of main sizing material coatings formulated appear on the market, have thin matter to brush similar painted, has thick matter blade coating to be called imitative porcelain.The problem that these coating coexisted is that coating is not water-fast, the easy slurry that decoloured of washing, and dirty being difficult to removes.Its reason is also can be water-soluble again after PVA and this family macromolecule water-sol dehydration of CWC are done admittedly.
Improving PVA base water-resistant coating has the report of many methods and application facet, and the most universal is to utilize the water-proofing performance that is produced after the PVA acetalation to carry out acetalation to handle.It is water-soluble that yet the acetal glue that complete acetalation forms also loses fully, can't be used for preparing water-soluble type building coating, can only be in the practical application with its part acetalation, and formation has certain water miscible water tolerance hemiacetal glue that will be good than PVA.Use this sizing material coatings formulated respectively, its water tolerance can only have improvement, at all Xie Guan.Another kind of method is the water-proof colloidal sol of energy after introduction is done admittedly when preparation coating, latex, and cooperates gluing with it, improves water-resistant coating; Or introduce active stopping composition,, improve the water-resistant coating energy, thus, will make the multiplication of coating cost, make making and brushing technique complicated with its gelling action.Also having a kind of method is multiple layer spraying method, promptly adds a cover the water-fast shellac varnish layer of film forming shape outside main coating.This method only to brush, spray material is effective, but for Spreed coated paint technology, can because of glue, enamelled coating adhere to the bright and clean porcelain light surface layer as porcelain that makes the blade coating gained if you would the fat dirt, lose sparkling and crystal-clear porcelain sense, also poor because of the adhesion layer ventilation property, coefficient of expansion peeling easy with scraping coating difference peels off.The problems referred to above are just attracting those skilled in the art that it is inquired into practicable solution.
The objective of the invention is to:,, make suitable spread coated paint cream with proper auxiliary agent, appropriate proportioning, certain technology controlling and process to being the coating of main sizing material with PVA and CWC; Scrape coating with the wetting maintenance of water-fast clever thin liquid preparation, coating is consolidated into can stand to wash and nondiscoloration does not play the water-fast finish coat of slurry with comprehensive physics chemical action, the decorations laminar surface does not have outer attached adhesive film, and the porcelain light quality sense of blade coating gained is kept for a long time.
Technical scheme of the present invention is to realize like this, adopt a kind of self not glued and can the water-fast spirit of water-proof low molecular material and PVA and acetal glue thereof and Mierocrystalline cellulose and derivative not water-proof macromolecule glue product such as (receiving) thereof as carboxymethyl, carboxyethyl cellulose be made into main agglutinate, add natural or artificial mineral's powder (carbonate, quartz, silicates breeze) stopping composition, make thick pulpous state lotion coating, on the blade coating what planarizing underlayer, form level and smooth, fine and smooth, bright and clean finish coat as porcelain, this finish coat has the good water resistance energy that the washing nondiscoloration plays slurry.
The present invention system is made up of the manufacture craft of base-material glue, coating plaster and water-fast clever three kinds of base-materials, below the present invention is described in detail:
1, base-material glue: in reactor, add quantitative washing water, be heated to 50-60 ℃, press the metering of base-material glue prescription and drop into PVA, stir, be heated to 95-98 ℃, be incubated to the PVA dissolving complete, be cooled to below 60 ℃, be metered into the prior solvent CWC of water logging and other components used by prescription, oxalic acid adds at last, fully stirs, make glue even, drip a little sulfuric acid or hydrochloric acid, regulate PH ≈ 6.5, go out still and promptly get base-material glue.Its component proportioning is as follows:
100 parts in water
PVA 3-10 part
The water logging solution of CWC(10%) 10-20 part
0.2 part of neck phthalic acid dibutyl ester
0.1 part of ethylene glycol (amine)
0.5 part in urea
0.1 part of oxalic acid
Coatings additive(s) commonly used is an amount of
2, coating plaster: in stirring (bucket), add a certain amount of base-material glue, start stirrer, progressively add round trip flight breeze (fineness 300 orders, whiteness 〉=90 degree), be accustomed to desired denseness, be whitewash cream to meeting knife-coat application.If need be painted, then before adding breeze, add colorant slurry (color paste consumption is pressed the depth of required color and allocated) earlier, make colorant glue, then with Icing Sugar, equally stir into cream with white material.Its proportioning is as follows:
Base-material glue: round trip flight breeze=2～3 part: 8-7 part
The colorant slurry is an amount of
3, water-fast spirit: put into quantitative 50-60 ℃ of clean clean hot water in the mixing drum of cleaning (bucket), start stirrer, drop into the batching component one by one by prescription, a kind of dissolving is complete, throws another kind of again.Add liquid material alcohol at last, fully dispersed with stirring is even, the naturally cooling clarification, filter transparent clear liquid, be water-fast clever finished product.Its component proportioning is as follows:
100 parts in water
Al
2(SO

31-3 part
MgCl
20.5-1.8 part
A kind of or two kinds of 1-5 parts in the sour sodium of silicon (aluminium, boron, carbon)
Glycerol (or ethylene glycol) 2-5 part
Through practical application, the present invention has the washing nondiscoloration, does not play the characteristics of slurry, and the coatings surface does not have outer attached adhesive film, can keep the sense of porcelain light quality for a long time.
