Problems solved by technology

[0004] Problem 1: High construction requirements
It needs to be composed of A and B groups. It is prepared and used at the construction site. The construction is limited by time and must be used up within 10 hours, otherwise it cannot be used after curing.
[0005] Question 2: For steel structures, the requirements for anti-corrosion surface treatment are high
[0007] Problem 1: It can only be sprayed indoors
If you encounter the original, bulky, indivisible or steel structure facilities that cannot be processed and combined in the factory, thermosetting powder coatings cannot be used
Therefore, the use of thermosetting powder coatings will be limited by whether the steel structure is new or old, large or small, and whether it is easy to assemble, so it cannot be widely used
[0008] Problem 2: No energy saving
Thermosetting powder coatings need to be sprayed under certain temperature baking conditions, so that the coating can change from dry powder solid to gel, and baking curing requires a lot of energy consumption, which does not meet the requirements of energy saving and enterprise cost saving advocated by the state

Embodiment

[0034] Prepare fifteen kinds of raw materials for preparing the product of the present invention according to the weight percentages in Table 1.

[0035] First, heat the oil-water amphoteric acrylic resin to 55°C in a glass-lined pot to make the resin thinner; heat the chlorinated paraffin and zinc stearate to 80°C-90°C in a glass-lined pot to dissolve them all;

[0036] Then, slowly add natural rubber to the heated acrylic resin under stirring, slowly add dissolved chlorinated paraffin and zinc stearate in sequence, then add tributyl phosphate and silicone oil, and stir for half an hour;

[0037] Next, add 70% of the prepared isopropanol, control the temperature at 30°C to 35°C, then add titanium dioxide, light calcium, organic silicon hollow microspheres, titanate coupling agent and ultraviolet absorber, and sand 4 to 5 hours until the fineness reaches below 20 μm;

[0038] Finally, in the state of high-speed beating, add toner, glycerin, acrylic acid and the remaining isop...

Abstract

The invention discloses a macromolecular preservative paint and preparing method, which comprises the following steps: allocating raw material with 55% filming material, 11% solvent, 11% paint adjuvant and 23% dye and fill; heating filming material to dissolve; stirring to add emulsion to emulsify; adding solvent, paint adjuvant to grind; beating; stirring; filtering; detecting viscosity; selecting filming material from oil-water amphiprotic acrylic acid resin, natural rubber, chlorcosane and zinc stearic acid; making isopropanol as solvent.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, more specifically to a polymer anticorrosion paint with acrylic resin as the main film-forming substance and a preparation method thereof. Background technique [0002] Coating is a kind of chemical product with convenient construction, low price, obvious effect and high added value rate. It not only has the function of preventing the surface of buildings, ships, machinery, etc. Strong fine chemical product. [0003] The existing widely used anti-corrosion fluorocarbon paint has good anti-corrosion properties, but it has the following problems: [0004] Problem 1: High construction requirements. It needs to be composed of A and B pairs, and it is prepared and used at the construction site. The construction is limited by time and must be used within 10 hours, otherwise it cannot be used after curing. [0005] Question 2: For steel structures, the requirements for anti-corrosion surfa...
