The invention relates to a concrete bridge structure surface protective coating material based on pure acrylic emulsion and a preparation method thereof. Most of the conventional concrete surface protective coatings are poor in carbonization resistance and ageing resistance and complex in brushing process steps. The concrete bridge structure surface protective coating material is prepared by mixing the following components together in parts by weight: 75 to 85 parts of pure acrylic emulsion, 1 to 3 parts of pure acrylic emulsion, 0.3 to 0.5 part of a water-based anti-aging agent, 1 to 3 parts of titanium pigment, 1 to 3 parts of sericite, 3 to 7 parts of a functional auxiliary agent system, 1.5 to 3.5 parts of a regulating auxiliary agent system, 0.5 to 2 parts of a leveling-type thickening agent and 5 to 10 parts of water, wherein the functional auxiliary agent system consists of a hydrophobing agent, a stain-resistant agent and an adhesive force accelerant in a mass ratio of 3:1:2; and the regulating auxiliary agent system consists of an antifoaming agent and a dispersant in a mass ratio of 1:6. By adopting the concrete bridge structure surface protective coating material, concrete achieves an excellent protection effect under an accelerated carbonization condition, the carbonization of the concrete is delayed, the ageing resistance of the concrete is excellent, the coating brushing process steps are simple, and all links from production to construction are safe and environment-friendly without environmental pollution.

The invention relates to an inner cavity painting device, an inner cavity painting method and a painting method for slide rail sleeves. The inner cavity painting device for the slide rail sleeve, including: bearing column, base, clamping beam, swivel seat assembly, clamping assembly and faucet plug; the base is connected to the lower end of the bearing column ; the swivel seat assembly is arranged on the base, and is used to lift the tail end of the slide rail sleeve and drive the slide rail sleeve to rotate around its lengthwise axis; the clamping assembly includes a cone A shell-shaped sealing disc and a joint bearing, the conical shell-shaped sealing disc abuts against and seals the opening at one end of the slide rail sleeve. The invention can automatically, efficiently and evenly finish the painting of the inner cavity, improves the consistency of the quality of the pouring primer, significantly shortens the time interval between painting and anodizing the surface of the slide rail sleeve, and further improves the quality of the slide rail sleeve. Anti-corrosion effect on the surface of the cylinder.

The invention relates to an environment-friendly nanoscale bottom infiltrated layer material used for protecting a concrete surface and a preparation method of the environment-friendly nanoscale bottom infiltrated layer material. A conventional infiltrated layer material used for protecting the concrete surface is extremely poor in permeability, can not guarantee the firm bonding with a concrete base, and is easy to fall off from the concrete surface under the action of external erosion conditions. The invention provides the nanoscale bottom infiltrated layer material which is prepared from an inorganic nano silicon dioxide solution, styrene-acrylic emulsion, pure acrylic emulsion, gamma-aminopropyl triethoxy silane, isobutyl triethoxy silane, sodium metaphosphate, tributyl phosphate and one of tetrabutyl orthosilicate, butyl acetate, sodium methyl silicate, acrylate and ethyl acetate. The environment-friendly nanoscale bottom infiltrated layer material can quickly infiltrate into concrete by certain depth and react with a concrete base material to seal pores inside the concrete, is good in bonding performance with a surface protective layer material, and can ensure the firm bonding between a concrete protective system and the concrete surface under the action of an outside environment and delay the occurrence of concrete diseases.

There is a kind of quick non-water bonderizing liquid, it belongs to chemistry treatment field of metal surface. The techonlogy is providing a kind of quick, normal temperature and short time bonderizing liquid. The technology scheme is, the proportion is: 5-15 poly vinyl alcohol butyric aldehyde, 60-100 alcohol, 4-10 orthophosphoric acid, 0.1-1 tannin, 12-30 pimelin ketone, 10-20 resin. The manufacturing method is: poly vinyl alcohol butyric aldehyde is added into alcohol and immersed for 24 hours, then adds in resin and pimeline ketone, heated and blended; the tannin is added into orthophosphoric acid and immersed for one hours, and adds in pimelin ketone and blended, then blended the two mixed liquid and gets the bonderizing liquid.

The invention discloses a multi-color coating method and a coated part; wherein, the method comprises at least the following steps: a layer of priming paint is coated on the whole face plate; a first middle paint is coated on a first area of the face plate; a first top finish is coated on the first middle paint; a second middle paint is coated on a second area of the face plate, and a second top finish is coated on the second middle paint. Since the method of using the same priming paint when coating two colors, the invention has the advantages of simplified paint coating process and improvedyield rate.

The invention relates to a polyvinyl chloride-polyvinylidene emulsion based concrete bridge structure surface protective coating material and a preparation method thereof. Most of existing concrete surface protective coatings are poor in carbonization resistance and ageing resistance and complex in painting process. The coating material is composed of 80-90 parts of polyvinyl chloride-polyvinylidene emulsion, 1-3 parts of bentonite, 0.3-1 part of aqueous antiager, 1-5 parts of titanium dioxide, 1-5 parts of sericite, 2-10 parts of functional assistant system and 2-9 parts of adjustment assistant system, wherein the adjustment assistant system is composed of antifoaming agent, dispersing agent and leveling thickener according to the mass ratio of 2:1:4. The coating material enables concrete to have excellent protective effects under accelerated carbonizing conditions, carbonization of the concrete is decelerated, the coating material is excellent in ageing resistance, the coating painting process is simple, all procedures from production to construction are safe and environment-friendly, and environment pollution is avoided.
