Problems solved by technology

[0004] Defect 1: No non-stick and waterproof properties, self-adhesive, chemical glue stickers (such as the "black small advertisements" that can be seen everywhere on telephone poles and other buildings) are difficult to peel off after being put on, and cannot be erased after writing with a water-based pen , affect the appearance and the cleaning intensity is strong;
[0005] Defect 2: The acid and alkali resistance is not strong, and the anti-corrosion performance is not high, so it is not resistant to the corrosion of various chemical gases. When encountering chemical gases, it will run, pop, drip, and leak, and the peeling will peel off, and the cement foundation of the wall will be damaged. Loose, causing safety accidents, not suitable for use in workshops of chemical companies;
[0006] Defect 3: Because of its poor waterproofness, and it cannot dry when exposed to water or soak in water, it has special requirements for construction climate conditions: it cannot rain within 2 hours before and after construction, causing inconvenience in construction

Embodiment

[0031] Prepare sixteen kinds of raw materials for preparing the product of the present invention according to the weight percentages in Table 1.

[0032] First, heat the oil-water amphoteric acrylic resin to 55°C in a glass-lined pot to make the resin thinner; heat the paraffin and stearic acid to 80°C-90°C in a glass-lined pot to dissolve them all;

[0033] Then, slowly add natural rubber to the heated acrylic resin under stirring, slowly add dissolved paraffin wax and stearic acid in turn, then add tributyl phosphate and silicone oil, and stir for half an hour;

[0034] Next, add 70% of the prepared isopropanol, control the temperature at 30°C to 35°C, and then add titanium dioxide, light calcium, organic silicon hollow microspheres, titanate coupling agent, ultraviolet absorber and antistatic agent, sanding for 4 to 5 hours until the fineness reaches below 20 μm;

[0035] Finally, in the state of high-speed beating, add water-based color paste, glycerin, acrylic acid and t...

Abstract

The invention macromolecular all-weather non-viscous latex paint and making method, which comprises the following steps: allocating raw material with 47% filming material, 18% solvent, 9.5% paint adjuvant and 25.5% 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, paraffin and stearic acid; making isopropanol as solvent.

Description

technical field [0001] The invention relates to a synthetic resin paint and a preparation method thereof, more specifically to an interior and exterior wall 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] Existing widely used water-based paints (such as water-based Nippon Paint) and solvent-based paints (such as elastic acrylic paints) have common performance and have the following defects: [0004] Defect 1: No non-stick and waterproof properties, self-adhesive, chemical glue stickers (such as the "black small advertisements" that can be seen everywhere on telephone poles and other buildings) are difficult to peel off after being put on, and cannot b...
