Abstract
The invention discloses a high-temperature-resistant anti-aging coating which is prepared from the following raw materials in parts by weight: 0.6-1 part of tar residues, 2-3 parts of polyethylene ether, 2-3 parts of tricalcium silicate, 0.3-0.5 part of manganese iso-octoate, 1-2 parts of tri(nonylphenyl) phosphate, 1-2 parts of 1, 2-dimethylimidazole, 3-4 parts of oxidized polyethlene wax, 3-5 parts of jade powder, 10-13 parts of titanium dioxide, 3-4 parts of butyl benzyl phthalate, 80-100 parts of hexamethylcyclotrisiloxane, 120-150 parts of methyl methacrylate, 130-200 parts of isooctyl acrylate, 6-10 parts of dodecyl acrylate, 500-600 parts of deionized water, 2-4 parts of ammonium persulfate, 4-6 parts of op-10 and 3-6 parts of a bonding aid. The high-temperature-resistant anti-aging coating disclosed by the invention is good in anti-aging property. Through an ultra-temperature test for 500 hours, the coating is not pulverized or bubbled, free of cracks and falling and good in high-temperature resistance, is particularly suitable for walls in tropical zones and plays a long protective role.
Description
?
Technical field
The present invention relates generally to paint field, particularly relates to a kind of high temperature resistant anti-aging coating.
Background technology
Be applied to body surface can be formed there is protection, the class I liquid I of solid-state film of decoration or property (as insulation, anticorrosion, mark etc.) or the general name of solid material, comprise oil (property) paint, water-miscible paint, powder coating.Paint is flowable liquid coating, comprises oil (property) paint and water-miscible paint.Paint take organic solvent as medium or high solid, solvent-free oil-base paint.Water-miscible paint is used water dissolving or the coating with water-dispersion.Coating is as one of the main material of house decoration, and the large percentage accounted in decorations, buys the whether qualified environment directly having influence on overall finishing effect and room of coating, sometimes even can produce harm greatly to the health of human body.At present along with the generation of various coating, the quality requirements of coating is also improved constantly, and improve constantly coating quality and can play very large help for building, life.
Summary of the invention
The object of the invention is just to provide a kind of high temperature resistant anti-aging coating.
The present invention is achieved by the following technical solutions:
A kind of high temperature resistant anti-aging coating, is characterized in that what it was made up of the raw material of following weight parts:

Described adhesive aid is made up of each raw material of following weight parts:
Methyl methacrylate 5-10, acrylate and vinyl acetate emulsion 20-25, aluminate coupling agent 2-3, Camphorwood micro mist 1-2, iso-borneol methacrylic ester 2-3, Potassium Persulphate 1-2, Sodium dodecylbenzene sulfonate 0.6-1, deionized water 13-20;
Above-mentioned methyl methacrylate is mixed with aluminate coupling agent, adds Sodium dodecylbenzene sulfonate, iso-borneol methacrylic ester after stirring, insulated and stirred 3-5 minute at 50-60 DEG C;
Camphorwood micro mist is joined in deionized water, after stirring, adds Potassium Persulphate, stir;
By each raw material mixing after above-mentioned process, join in acrylate and vinyl acetate emulsion, 300-400 rev/min of dispersed with stirring 15-20 minute, obtains described adhesive aid.
A preparation method for high temperature resistant anti-aging coating, is characterized in that comprising the following steps:
(1) get the 50-60% of above-mentioned methyl methacrylate weight, the 50-60% of Isooctyl acrylate monomer weight, dodecyl acrylate mixing, obtain monomer a;
(2) remaining methyl methacrylate, Isooctyl acrylate monomer are mixed with hexamethyl cyclotrisiloxane, butyl benzyl phthalate, insulated and stirred 3-5 minute at 60-70 DEG C, is cooled to normal temperature, obtains monomer b;
(3) get op-10 to mix with the 10-20% of above-mentioned deionized water weight, add ammonium persulphate, being increased to temperature is 60-70 DEG C, insulated and stirred 20-30 minute, drips above-mentioned monomer a, dripped off in 2-4 hour, be incubated 20-30 minute at the temperature disclosed above after dropwising, obtain seed emulsion;
(4) get oxidized polyethlene wax, be heated to 60-70 DEG C, add 1,2 dimethylimidazole, be stirred to normal temperature, add the 20-30% of residue deionized water weight, stir, obtain liquid a;
(5) in above-mentioned seed emulsion, add liquid a, stir, drip monomer b, time for adding is 100-120 minute, after dropwising, at 70-80 DEG C, is incubated 1-2 hour, and cooling filters discharging with 200-250 eye mesh screen;
(6) material above-mentioned steps (5) obtained mixes with each raw material of residue, and 800-1200 rev/min of dispersed with stirring 20-30 minute, obtains described high temperature resistant anti-aging coating.
Advantage of the present invention is:
Coating ageing resistance of the present invention is good, and through the test of 500 hours ultrahigh-temperature, coating is without efflorescence, peel off without bubbling, flawless, nothing, and high thermal resistance is good, is specially adapted to the body of wall use of torrid areas, can plays permanent protected effect.The methyl methacrylate that adhesive aid of the present invention adds can form colloidal state in water, mixed and modified with iso-borneol methacrylic ester, Potassium Persulphate, acrylate and vinyl acetate emulsion etc., has very strong bond effect, can improve film coated surface cohesiveness and stability.
