Problems solved by technology

[0004] In the existing technology, during the production and painting process of the steel plate, when the diluent volatilizes outward, pores will be formed, and the sealing ability of the coating on the steel plate will decrease. When the steel plate is used outdoors, corrosive gases or The liquid enters the pores, reaches the steel plate, and corrodes the steel plate. As a result, the performance of the color plate is reduced or even destroyed

Embodiment 1

[0025] The preparation method of special color plates for animal husbandry and breeding, the specific steps are as follows:

[0026] Step 1. Pretreatment: use galvanized steel sheet or galvanized steel sheet as the substrate, the galvanized substrate is a hot-dip galvanized substrate, and the amount of zinc coating Z: ≥150g / m 2 ; The strip is fed by the decoiler, and the strip is sent to the pretreatment section through the tensioner, and the surface of the strip is pretreated to improve the adhesion of the plate surface. The surface pretreatment is degreasing and cleaning; the degreasing and cleaning temperature control At 65℃, the pH value of the cleaning solution is controlled in the range of 8-9 to ensure thorough cleaning of impurities on the surface of the strip. After washing with water, it is dried by hot air;

[0027] Step 2. Passivation: The strip steel after pretreatment enters the chemical coating machine, and a layer of water-based chromium compound is applied to the su...

[0039] The preparation method of special color plates for animal husbandry and breeding, the specific steps are as follows:

[0040] Step 1. Pretreatment: use galvanized steel sheet or galvanized steel sheet as the substrate, the galvanized substrate is a hot-dip galvanized substrate, and the amount of zinc coating Z: ≥150g / m 2 ; The strip is fed by the decoiler, and the strip is sent to the pretreatment section through the tensioner, and the surface of the strip is pretreated to improve the adhesion of the plate surface. The surface pretreatment is degreasing and cleaning; the degreasing and cleaning temperature control At 45℃, the pH value of the cleaning solution is controlled in the range of 9-10 to ensure thorough cleaning of impurities on the surface of the strip. After rinsing with clean water, it is dried by hot air;

[0041] Step 2. Passivation: The strip steel after pretreatment enters the chemical coating machine, and a layer of water-based chromium compound is coated on ...

Embodiment 3

[0053] The preparation method of special color plates for animal husbandry and breeding, the specific steps are as follows:

[0054] Step 1. Pretreatment: use galvanized steel sheet or galvanized steel sheet as the substrate, the galvanized substrate is a hot-dip galvanized substrate, and the amount of zinc coating Z: ≥150g / m 2 ; The strip is fed by the decoiler, and the strip is sent to the pretreatment section through the tensioner, and the surface of the strip is pretreated to improve the adhesion of the plate surface. The surface pretreatment is degreasing and cleaning; the degreasing and cleaning temperature control At 55°C, the pH value of the cleaning solution is 8.5 to ensure thorough cleaning of impurities on the surface of the strip. After washing with water, it is dried by hot air;

[0055] Step 2. Passivation: The strip steel after pretreatment enters the chemical coating machine, and a layer of water-based chromium compound is coated on the surface of the strip steel. T...

Abstract

The invention provides a preparation method of colorful plates special for livestock breeding. Substrates are fed in a roller coating unit after surface cleaning and passivation; a three-roller reverse coating process is used; in front coating layers, primers use high-corrosion-resistance polyurethane primers, and finishing coats use high-corrosion-resistance PE polyester finishing coats; in backcoating layers, three-layer ultra-corrosion-resistance epoxy back paint is used; raw materials of the used paint are not reacted with acid or alkaline chemicals; ultrathin nanoparticles in the raw materials of the paint can effectively eliminate the gap defect caused by large-particle-size aggregates; and hot melting self-repair materials preferably eliminate solvent holes in conventional coatinglayers to form perfect closed paint films so as to achieve ultrahigh closing capacity and acid and alkali resistance.

Description

Technical field [0001] The invention belongs to the technical field of color plate manufacturing, and specifically belongs to a preparation method of color plates special for animal husbandry and breeding. Background technique [0002] Color plate, also known as color steel plate in the industry, color coated plate. Color coated steel plate is made of cold-rolled steel plate and galvanized steel plate as the substrate, after surface pretreatment (degreasing, cleaning, chemical conversion treatment), coating with paint in a continuous method (roll coating method), baking and cooling Into the product. Coated steel plate has light weight, beautiful appearance and good corrosion resistance, and can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, electrical industry, etc. Good results such as wood, efficient construction, energy saving and pollution prevention...
