Abstract
The invention relates to a method for preparing a water-based coating composition of automobile glass seals, which comprises the following steps of: preparing 100 weight parts of component A by mixing 20 to 50 nano units of nano water-based emulsion mainly containing at least one cross-linkable resin and polyethylene; and mixing the 100 weight parts of component A and 5 to 20 weight parts of component B, namely water-based cross-linking agent. Compared with the prior art, the water-based coating composition has the advantages of strong wear resistance, good slide and the like.
Description
Technical field
The present invention relates to a kind of water-based coating composition, especially relate to a kind of preparation method of water-based coating composition of automobile glass seals.
Background technology
To the improvement of close groove wear resisting property of vehicle glass sealing element rubber and surperficial sliding capability, generally all to reach at the certain material of its surface-coated.What adopt the earliest is the flocking cladding process, however this method cost an arm and a leg, and process is loaded down with trivial details, progressively coated coating replaces over nearly 10 years.
Coating covers promptly passes through spraying method in brief, a kind of special polymeric coating material is sprayed to seal surface, film in seal surface formation, the main effect of this coating film is that the close groove of automobile is in lower slip on glass, by means of abrasion property, smooth property and low frictional properties, reaching automobile window glass can successfully slide up and down enduringly.
The coating of Shi Yonging is the oiliness coating that contains the polydimethylsiloxanepolymer polymer matrix the earliest, and this coating is when producing good frost resistance, general low sliding and excellent finish and feel, and common mechanical is too not firm usually.And under exceedingly odious weather condition, the condition of for example hot and cold, wind and rain is descended, elastomer portions branch wherein exposes, not to lose gradually in filming by the silicone of chemical bonding or the coating ingredients of fluorocarbon polymer, cause elastomer portion surface sliding to reduce, this is that people are undesirable.Silicone also can be penetrated into coatingsurface and transfer near surface therefrom, thereby has influence on subsequently coating or operation.In addition, the fluorocarbon polymer cost is very high, also becomes one of its shortcoming.The more important thing is that solvent-based coating does not more and more satisfy industrial to low volatilization organic content (VOC) coating and environment amenable demand.
Though also the someone improves and has developed water base silicone coating afterwards, adopt the spherical siloxanes addition manner of solid to reach wear-resisting primary demand, also can't avoid relatively poor tear strength that silicone itself brought and the shortcoming of easily oozing out.
Summary of the invention
Purpose of the present invention is exactly the preparation method that the water-based coating composition of the automobile glass seals that a kind of wear resistance is strong, sliding is good is provided for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of preparation method of water-based coating composition of automobile glass seals, it is characterized in that, this method is to be that the nanometer water-base emulsion of 20～50 nanometer units of main body is mixed and made into A component 100 weight parts with containing at least a crosslinkable resin and a kind of polyethylene, mixes as B component 5-20 weight part with at least a water base linking agent.
Described A component is by 10～70 weight part crosslinkable resins, 0.1～1 weight part defoamer, 0.1～1 weight part polyether silicone flowing additive, 1～15 weight part nanometer water-base emulsion, 0.1～2 weight part flow agents, 0.1～2 weight part thickening materials, 1～10 weight part solubility promoter, 1～10 parts by weight of deionized water mixes.
Described crosslinkable resin is selected from one or more in polycarbonate, polymeric amide, polyesteramide, urethane or the polyacrylic ester, described defoamer comprises mineral oils or type siloxane, described flow agent comprises polyacrylate(s) or modified organic silicon class, described thickening material comprises caustic solubility esters of acrylic acid or urethane associativity class, described solubility promoter class comprises alcohols or two ethers, and described nanometer water-base emulsion is the nanometer water-base emulsion that contains 20～50 nanometer units of polyethylene 70～80wt%.
Described water base linking agent is selected from polymeric polyisocyanate, carbamate, polyepoxide, have the compound of at least two cyclic carbonate groups and in the polyanhydride one or more.
Described polyepoxide comprises boron trifluoride amine complex epoxy hardener, polyamide modified epoxy hardener or aminoamide epoxy hardener, all contain at least two cyclic carbonate groups, described polyanhydride comprises 4-methyl hexahydrophthalic acid anhydride or inner methylidyne tetrahydric phthalic anhydride.
The present invention selects a kind of high rigidity polycarbonate, polymeric amide, polyesteramide, urethane, polyacrylic ester as basic conjunctiva material, and then the adding polyethylene is the nanometer water-base emulsion of 20～50 nanometer units of main body, addition main body polycarbonate, polymeric amide, polyesteramide, urethane, polyacrylic ester 5%～20% between, reach good abrasion resistance and sliding capability, overcome the problem that above old coating is left over.This coating and can adopt simply except that good wear resistance frost resistance and surperficial sliding capability is provided, and environment amenable process method construction impels every cost to reduce, the value that provides large-scale popularization to use.Compared with prior art, the present invention both had the following advantages:
1. when having reached vehicle glass and having slided up and down, good abrasion resistance and sliding capability;
2. good weathering resistance, high temperature, high and cold, all can keep superperformance;
3. owing to all adopt water as diluting solvent, environmental protection, energy-conservation, VOC discharging etc. are with the obvious advantage;
4. the polyethylene nanoemulsions is cheap, and cost reduces, and has possessed the value that large-scale popularization is used;
5. construction is simple, and is stable.
