Abstract
The present invention relates to a functional liquid paint used in magnesium backer. It consists of base body and face budge. They all includes special property modification alkyd resin liquid paint, which has good interlamellar clunging, good gloss and color retention, high abrasive resistance, salt spray resistance, and cold and heat resistance. It needs only one set of production equipment, so the cost is largely reduced. The baking temperature of base bedye is reduced from 200Deg.c in present technique to 140Deg.c-160Deg.c; the energy cost is largely reduced. The thickness covered of base bedye is reduced from 50-80 micro in present technique to 25-30 micro, the cost of paint is reduced and when repaint the whole membrane changes little, which is good for the latter equipment.
Description
Technical field
The present invention relates to a kind of liquid coating, relate in particular to a kind of functional liquid coating that is used for magnesium aluminium alloy base material.
Background technology
The present domestic equal dependence on import of coating that is used for magnesium aluminium alloy base material (as mobile phone, notebook computer casing), priming paint adopts powder coating, finish paint adopts liquid coating, so coating equipment disunity, need two complete equipments during production, invest greatlyyer, and the powder coating of priming paint needs to toast under the condition more than 200 ℃, and energy consumption is bigger.About 50～80 microns of primer base thickness, thickness is 100～150 microns during recoat, and thickness is extremely inhomogeneous, is unfavorable for follow-up assembling.At the high standard requirement that loose porous magnalium is coated, liquid coating of the prior art still can not be taken into account high adhesive force, high abrasion, the salt spray resistance of this series products, the performance of cold-resistant thermal cycling.
Summary of the invention
The purpose of this invention is to provide the low functional liquid coating that is used for magnesium aluminium alloy base material of a kind of high adhesive force, high abrasion, salt spray resistance, cold-resistant thermal cycling and production cost.
The present invention is implemented by the following technical programs: a kind of functional liquid coating that is used for magnesium aluminium alloy base material, the matched coating that it is made up of priming paint and finish paint, the component of described priming paint comprises color stuffing, aminoresin, dispersion agent, flow agent, solvent, the component of described finish paint comprises color stuffing, aminoresin, dispersion agent, flow agent, solvent, and described priming paint and finish paint also contain vibrin respectively.
The structural formula of described vibrin is:
In the formula, R is that carbonatoms is to be equal to or greater than 5 hydrocarbon base.
The weight percentage of each component is in the described priming paint: vibrin 20%～50%, color stuffing 10%～45%, aminoresin 10%～25%, dispersion agent 1%～3%, flow agent 0.05%～0.8%, solvent 10%～30%.
Also comprise following ingredients by weight percent in the described priming paint: functional filler 3%～5%, adhesion promoter 0.5%～4%.
The weight percentage of each component is in the described finish paint: vibrin 20%～50%, color stuffing 5%～20%, aminoresin 10%～25%, dispersion agent 1%～3%, flow agent 0.05%～0.8%, solvent 10%～30%.
Also comprise following ingredients by weight percent in the described finish paint: antiwear assistant 0.2%～0.5%, adhesion promoter 0.5%～4%.
Described adhesion promoter is to include the compound that following formula is represented,
In the formula, m is the integer less than 5, and X represents :-OH, Y represents :-OCH
2CH
3, Z represents:
W represents :-CH=CH
2
Compared with the prior art the present invention has following advantage: priming paint of the present invention and finish paint all adopt the liquid coating of the vibrin that comprises special modification, ply adhesion is good, has good guarantor's light tint retention, good to the every performance property taken into account of magnalium, and have high adhesive force, high abrasion, salt spray resistance, cold-resistant thermal cycling.Owing to only need a cover production unit, make full use of device resource and reduced investment.The storing temperature of priming paint is reduced to 140 ℃～160 ℃ by 200 ℃ of the prior art, greatly reduces energy consumption.The applied thickness of priming paint is also reduced to 25～30 microns by 50～80 microns of the prior art, and the usage quantity of coating has been saved cost less, and total film thickness does not have too big variation during recoat, helps the assembling of back workshop section.
Embodiment
Embodiment:
A kind of functional liquid coating that is used for magnesium aluminium alloy base material, the matched coating that it is made up of priming paint and finish paint, priming paint takes by weighing raw material according to following proportioning: vibrin 30, color stuffing 30, functional filler 4, aminoresin 20, dispersion agent 2, flow agent 0.5, adhesion promoter 3, solvent 10.5; Finish paint takes by weighing raw material according to following proportioning: vibrin 35, color stuffing 15, aminoresin 24, dispersion agent 2, flow agent 0.7, antiwear assistant 0.4, adhesion promoter 3, solvent 19.9.Wherein, the structure of vibrin
Formula is:
In the formula, R is that carbonatoms is to be equal to or greater than 5 hydrocarbon base.
Import top coat of the prior art is a liquid and priming paint is powder, and priming paint of the present invention and finish paint all are liquid, ply adhesion is good, owing to adopted the vibrin of special modification to have good fullness ratio and intensity, the acrylic resin of grafting has good guarantor's light tint retention, good to the every performance property taken into account of magnalium, and have high adhesive force, high abrasion, cold-resistant thermal cycling, in priming paint, add functional filler and strengthened its salt fog resistance greatly.Also comprise weight percentage and be 3% adhesion promoter in priming paint and finish paint, described adhesion promoter is to include the compound that following formula is represented,
In the formula, m is the integer less than 5, and X, Y, Z, W are all active group, and X represents :-OH, Y represents :-OCH
2CH
3, Z represents:
W represents :-CH=CH
2Owing to the active group that adhesion promoter is contained is more, make coating under severe cruel environment, still good bonding force be arranged to ground.
Owing to only need a cover production unit, make full use of device resource and reduced investment.The storing temperature of priming paint is reduced to 140 ℃～160 ℃ by 200 ℃ of the prior art, greatly reduces energy consumption.The applied thickness of priming paint is also reduced to 25～30 microns by 50～80 microns of the prior art, and the usage quantity of coating has been saved cost less, and total film thickness does not have too big variation during recoat, helps the assembling of back workshop section.
