Abstract
The invention discloses an organic silicon modified acrylic resin primer of plastic articles. The primer comprises the following constituents by weight percent: 45-55% of organic silicon modified acrylic resin, 10-15% of hexamethyl alcohol etherified amino resin, 20-25% of pigment, 6-15% of accessory ingredient and the balance of solvent. The primer has better compatibility to the plastic articles made of different materials, so that waste and trouble caused by frequent change of paint during construction can be reduced by utilization of such product, and the working efficiency is improved greatly. The product in the invention has better boiling resistance and thermal cycling resistance.
Description
Technical field
The invention belongs to chemical technology field, relate to a kind of priming paint, be specifically related to a kind of organosilicon modified crylic acid resin priming paint of plastic component.
Background technology
Plastic paint is similar to the used coating of other metal partss, also is divided into priming paint, base coat, varnish or finish paint etc., priming paint can directly be coated in through surface-treated plastic bottom material table and on, the plastic covering components list and current mark and defective.Along with the fast development of automobile and shipping industry, the deadweight of automobile and boats and ships has light-weighted trend, and therefore, the plastic component of various materials more and more is applied on the vehicles such as automobile.
Make in the industry at current plastic component coating, matrix resin adopts acrylic resin to be equipped with other raw material mostly in its prescription, and production technique processes routinely.(publication number CN 1908093 A) disclose a kind of colorless high-performance acrylic acid rust-inhibiting primer as Chinese patent " colorless high-performance acrylic acid rust-inhibiting primer ", each components contents is in this priming paint: acrylic resin 33-53%, white composite silicon titanium rust-proof powder 36-56%, anti-settling agent 1-10%, aminoresin 1-8%, mixed solvent 1-3%, this priming paint has following advantage: utilize the white composite silicon titanium rust-proof powder with premium properties and reasonable price to replace red lead to the people, the equal toxicological harmless of coenocorrelation, and use other color dexterously, filler, auxiliary agent and obtaining has unique colourless, simultaneously extremely strong with iron and steel affinity and anode corrosion inhibition own, the salt tolerant soak time can reach more than 600 hours.But the problem that exists is that this plastics priming paint can't be suitable for the plastic component of unlike material simultaneously, but makes at the plastic component of certain material, has increased many inconvenience when therefore giving the accessory application.In addition, existing commercially available plastics priming paint product sticking power is not strong, and boiling resistance is poor, and work-ing life is short.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, the organosilicon modified crylic acid resin priming paint of a kind of with low cost and strong adhesion, plastic component that the cold-and-heat resistent alternation is good is provided.
Above-mentioned purpose of the present invention is achieved by the following scheme:
A kind of organosilicon modified crylic acid resin priming paint of plastic component, this priming paint is by organosilicon modified crylic acid resin, pregnancy alcohol etherificate aminoresin, pigment, auxiliary agent and solvent composition, and the weight percent of each component is:

Wherein, above-mentioned organosilicon modified crylic acid resin is formed by active methoxyl group, oxyethyl group, organic hydroxy silicate intermediate and Hydroxylated acrylic resin reaction.
For further improving boiling resistance energy and the cold-and-heat resistent alternation performance of priming paint, the weight percent of above-mentioned each component is:
Do choosing ground, the weight percent of above-mentioned solvent composition is: dimethylbenzene 50～70%, butanone 20～35%, N-BUTYL ACETATE 10～25%.
Further preferably, the weight percent of above-mentioned solvent composition is: dimethylbenzene 55%, butanone 25%, N-BUTYL ACETATE 20%.
The viscosity of above-mentioned organosilicon modified crylic acid resin priming paint is 150～600mpa.s, and solid content is 40～50%, and hydroxyl value is 60, and acid number is 8～9mgKOH/g, and second-order transition temperature is 85 ℃, and minimum film-forming temperature is 45 ℃; Viscosity＜100 mpa.s of described pregnancy alcohol etherificate aminoresin, solid content is 40～50%, cl content is 12%.
Wherein, above-mentioned auxiliary agent is dispersion agent, viscosity control agent, flow agent and defoamer.
Preferably, above-mentioned dispersion agent weight percent be 0.5～0.8%, viscosity control agent is 5～10%; The weight percent of described flow agent is 0.1～0.6%; The weight percent of described defoamer is 0.1～0.5%.
When a kind of plastic component priming paint of the present invention prepares, take by weighing each raw material by proportioning, earlier organosilicon modified crylic acid resin being added dispersion agent stirs, add pigment and solvent while stirring, dispersion grinding to fineness less than 30 microns dischargings, add flow agent after cooling while stirring, stirring gets final product.
Compared with prior art, the beneficial effect that has of the present invention is as follows:
1, product of the present invention is main component with the organosilicon modified crylic acid resin, being equipped with an amount of pigment, dispersion agent, flow agent and solvent makes, its principal feature is the primer painting that is suitable for various plastic component, plastic component to unlike material all has good matching capacity, owing to frequently change waste and the trouble that lacquer causes, improved working efficiency greatly when therefore using this product can reduce construction.
2, product of the present invention has good boiling resistance and cold-and-heat resistent alternation.Through check, this product all is better than currently available products in the index of aspects such as pencil hardness, sticking power, shock strength, water tolerance.
