Technical field
The present invention relates to the technical field of the technical field of coating, more particularly to elastic coating.
Background technology
Elastic coating is, with synthetic resin emulsion as base material, to be formulated with pigment, filler and auxiliary agent, applies certain thickness
Afterwards, with cover because base material stretch produce fine cracks resilient functional coating.Generally include solvent-borne type, emulsion-type and
Inorganic type elastic coating.Wherein solvent-borne type, emulsion-type elastic coating elongation percentage are high, and film-formation result is good, but intensity, hardness are relatively
Difference, weather-proof, poor heat resistance, and inorganic type elastic coating film-formation result is relatively poor, elasticity is general relatively low.
The content of the invention
It is an object of the invention to propose that a kind of intensity, hardness are higher, heat-resisting, weatherability is excellent, and hates with good
The preparation method of the organic elastomer coating of water effect.
Technical scheme is as follows：
A kind of preparation method of hydrophobic type elastic coating, comprises the following steps：
(1) aerosil, aluminium sesquioxide are mixed with deionized water, adds coupling agent, stirred at 30～40 DEG C
15～30min is mixed, adds calcined kaolin to stir thereafter；
(2) slurry that will be obtained by step (1) is added in pure-acrylic emulsion, adds dispersant, wetting agent, film forming to help thereafter
Agent, hydroxymethyl cellulose stirs, and adds Sodium styrene sulfonate, is again stirring for uniformly, that is, obtaining the hydrophobic type elasticity
Coating.
Preferably：The coupling agent is silane coupler.
It is also preferred that：The dispersant is polyvinyl alcohol.
It is also preferred that：The coalescents are propylene-glycol ethyl ether.
It is also preferred that：The wetting agent is Propylene Glycol.
It is also preferred that：The component in parts by mass, including 30～50 parts of pure-acrylic emulsion, dispersant 0.5～1.5
Part, 5～10 parts of wetting agent, 1.0～1.5 parts of coupling agent, 0.5～2.5 part of coalescents, 0.3～0.5 part of hydroxymethyl cellulose,
