Abstract
The invention relates to an aqueous paint, and specifically relates to an aqueous hammer paint, and belongs to the technical field of chemical industry. An aqueous acrylic acid modified epoxy emulsion is used as a film forming substance; acrylic acid monomer and epoxy resin conduct a grafting copolymerization reaction to introduce strong hydrophilic group -COOH into the epoxy resin and carry out water-borne modification on the resin; the prepared emulsion particle is fine (reaching nanometer level) and stable. Acrylic acid resin has excellent gloss retention, colour retention and ultraviolet resistance; and epoxy resin has excellent alkali resistance, chemicals resistance solvent resistance and extraordinary adhesive force; therefore the paint film has excellent comprehensive performances.
Description
Technical field
The present invention relates to a kind of water-miscible paint, be specifically related to a kind of aqueous hammer paint, belong to chemical technology field.
Background technology
Hammer paint is a kind of artistic coating, and the floral designs that its coating surface appears are similar to net head hammer and knock the decorative pattern that metal sheet is pounded out, and are used for the coarse injustice that foundry goods is covered the surface in a large number, increase aesthetic feeling.Conventional solvent type hammer paint contains organic solvent, produce and construction in very harmful to environment and operator.
Summary of the invention
The objective of the invention is for overcoming the weak point of above-mentioned prior art; A kind of aqueous hammer paint is provided; Select for use aqueous acrylic modified epoxy emulsion as filmogen; Acrylic monomer and Resins, epoxy graft copolymerization; In Resins, epoxy, introduce strongly hydrophilic group-COOH; Make the resin Water-borne modification, the emulsion particle that makes is thin (can reach nano level), good stability.Acrylic resin has good guarantor's light, tint retention and ultraviolet resistance, and Resins, epoxy has excellent alkali resistance, chemical-resistant and solvent resistance, and fabulous sticking power, the paint film excellent combination property.
The present invention realizes with following technical scheme: a kind of aqueous hammer paint; It is characterized in that: this hammer paint selects for use aqueous acrylic modified epoxy emulsion as filmogen; Acrylic monomer and Resins, epoxy graft copolymerization; In Resins, epoxy, introduce strongly hydrophilic group-COOH; Make the resin Water-borne modification, the emulsion particle that makes.
A kind of construction technology by the described aqueous hammer paint of claim 1; It is characterized in that: adopt the secondary spraying application; Spray the 1st road aqueous hammer paint on the surface that is sprayed with priming paint; Require the evenly lid end; After room temperature leaves standstill 15～20min or surface drying; Spray the 2nd road aqueous hammer paint; Behind about 5rain; Just demonstrate even beauty, the mallear stria of the metalluster that glimmering; After 10～15rain treat its stable after, put oven dry in people's baking oven (120 ℃, 10～15min); Paint film is a complete drying, forms bright, plentiful mallear stria paint film.
Advantage of the present invention is: this aqueous hammer paint utilizes surface tension effect, adds people's mallear stria auxiliary agent to promote the formation of mallear stria.Because the surface tension of mallear stria auxiliary agent is extremely low, the mallear stria auxiliary agent is transferred to film coated surface in the paint film expansion process, and the recess surface tension is lower, and the high spot surface tension is higher, and lacquer liquid is pulled to bump pad from recess, thereby concavo-convex more obvious, and stereoscopic sensation is stronger.Along with the time ask prolongation, solvent descends, viscous resistance increases, drying varniss shrinks and produces internal stress simultaneously.When viscous resistance, internal stress and surface tension balance, paint film " is freezed ", forms mallear stria.
