Abstract
The invention relates to ornamental thermoplastic crylic acid paint, which is made up of base material, pigment, assistant and solvent, mentioned base material is thermoplastic acroid resin whose character is changed by saturated fatty acid, its viscosity is 800-2000 mPa.s, molecule of the resin contains saturated fatty acid radical which is about 5-30% of resin weight, at the same time it also contains tertiary carbonate which is about 5-20% of resin weight, each element of the paint and their weight proportion is as follows: base material (counted by solid) 100, pigment 3-90 assistant 0.3-2, solvent 145-160. It applies to be used as ornamental face-paint for metals and plastics, the build, glossiness and resistance to element is excellent, the storing is stable.
Description
Technical field
The present invention relates to a kind of decorative thermoplastic acrylic paint, more specifically say, relate to a kind of thermoplastic acrylic paint of ornamental saturated fatty acid modification.
Background technology
Though traditional thermoplastic acrylic paint has better weather, ornamental relatively poor, and in storage process, often occur because of the bad layering of wettability, when humidity is higher, use this coating also to be prone to whiting.Various types of modified thermoplastic acrylic coatings have appearred for overcoming these shortcomings.Wherein modal is phenylethene modified thermoplastic acrylic paint.Widen with the phenylethene modified solubility parameter gap of the hard section of acrylic soft resin that can make, part has improved package stability and the mechanical property of making coating, and particularly gloss is improved.But but influenced the weathering resistance of thermoplastic acrylic paint,, had a strong impact on the outdoor protection of coating along with vinylbenzene increase weathering resistance of content in resin is on a declining curve.
Summary of the invention
The objective of the invention is to, a kind of shelf-stable is provided, the decorative thermoplastic acrylic paint of the fullness ratio of coating, gloss and good weatherability after the film forming.
Realize the technical scheme of the object of the invention: a kind of decorative thermoplastic acrylic paint, by base-material, pigment, auxiliary agent and solvent composition, described base-material is the thermoplastic acrylic resin of saturated fatty acid modification, viscosity is 800～2000mPas, in this molecular resin, contain ratio with weight resin and be 5～30% saturated fatty acidic group, also contain ratio with weight resin simultaneously and be 5～20% tertiary carbon acidic group, the weight ratio of forming each component of this coating and each component is as follows:
Base-material (in solid) 100
Pigment 3～90
Auxiliary agent 0.3～2
Solvent 145～160.
In the above-mentioned coating, described solvent is the mixed solvent of being made up of benzene class, alcohols and ester class, and wherein alcoholic solvent accounts for 10～45% (weight percents) of mixed solvent total amount.
In the above-mentioned coating, described auxiliary agent is at least 3 kinds in defoamer, flow agent, wetting agent, catalyzer and the dispersion agent.
In the above-mentioned coating, described pigment is traditional inorganic and/or pigment dyestuff, according to the user requirement of product colour is determined.
Technique effect of the present invention: technical scheme of the present invention is to use the thermoplastic acrylic resin of saturated fatty acid modification as base-material, is mixed with to have the high-decoration thermoplastic acrylic paint.Owing in molecular resin, introduced the saturated fatty acidic group rather than the unsaturated fatty acids acidic group of an amount of (5～30%) as base-material, therefore, not only improved fullness ratio, gloss and the weathering resistance of coating after the package stability of coating and the coating film forming, and to the not influence of coating dryness.Also introduced the tertiary carbon acidic group of an amount of (5～20%) in the molecular resin of above-mentioned base-material simultaneously, the resistance to chalking of coating has obvious effect after the coating film forming to improving for it.To adopting technical solution of the present invention institute coatings formulated and existing similar coating, carry out the check of the various performances of coating after package stability and the film forming simultaneously, it the results are shown in Table 1 and table 2.Assay in the table can show: the fullness ratio of coating is better than phenylethene modified thermoplastic acrylic paint and traditional thermoplastic acrylic paint after the coating film forming of the present invention; Its 60 ° of gloss obviously are better than traditional thermoplastic acrylic paint, also are higher than phenylethene modified thermoplastic acrylic paint; Its water tolerance, weathering resistance (artificial accelerated aging) obviously are better than phenylethene modified acrylic coating, also are higher than traditional thermoplastic acrylic paint; Its coating dryness (comprise surface drying and do solid work) is all close with existing like product; The excellent storage stability of coating (40 ℃ 1 month, are not seen layering).
