Problems solved by technology

Existing reflective paints are all mixed with anti-mold agents in liquid paints. However, most of these agents mixed into paints are pesticides, which are more or less toxic, which is harmful to human health and expensive. It is relatively expensive, therefore, it is urgent to find a cheap, non-toxic, environmentally friendly coating with antibacterial and insect-resistant effects

Embodiment 1

[0017] Example 1: 10% rosin resin, 20% acrylic emulsion, 8% organic pigment, 4% water-based color essence, 43% reflective glass beads, 1% defoamer, 2% plant insect-resistant and bacteriostatic agent, and 2% ethanol and water 10% to obtain the reflective paint, and the fineness of the reflective glass beads is 400 mesh.

Embodiment 2

[0018] Embodiment 2: 20% of rosin resin, 15% of acrylic emulsion, 8% of organic pigment, 2% of water-based color essence, 30% of reflective glass beads, 2% of defoamer, 3% of plant insect-proof and bacteriostatic agent, and 5% of ethanol , water 15% and mix to get reflective paint, the fineness of the reflective glass beads is 450 mesh.

Embodiment 3

[0019] Embodiment 3: 15% of rosin resin, 15% of acrylic acid emulsion, 6% of organic pigment, 3% of water-based color essence, 33% of reflective glass beads, 2% of defoamer, 2% of plant insect-proof and bacteriostatic agent, and 4% of ethanol , water 20% and mix to get the reflective paint, the fineness of the reflective glass beads is 450 mesh.

[0020] The plant insect-proof and bacteriostatic agent is prepared by the following method:

[0021] 1) Crush Pyrethrum diffusa into coarse powder, and pass through a 20-mesh sieve;

[0022] 2) Reflux extraction: reflux extraction of Pyrethrum diffusa coarse powder with 90% ethanol at a temperature of 75-80°C for 2-3 hours to obtain a concentrated solution;

[0023] 3) Macroporous resin adsorption purification: the obtained concentrate is separated and enriched by macroporous adsorption resin, followed by water, 30% hydrous ethanol, 40% hydrous ethanol, 50% hydrous ethanol, 60% hydrous ethanol, and 70% hydrous ethanol. Gradient elu...

Abstract

The invention relates to an environment-friendly reflective coating, and belongs to the technical field of coatings. The coating is prepared from the following components in percentage by weight: 10-20% of rosin resin, 9-20% of an acrylic emulsion, 2-8% of an organic pigment, 2-4% of water-based color concentrate, 30-60% of reflective glass beads, 1-2% of a defoamer, 2-3% of a plant insect prevention bacteriostatic agent, 2-5% of ethanol and 10-20% of water. The fineness of the reflective glass beads is 400-450 meshes. The environment-friendly reflective coating has good waterproofness and washability, and is bright and lasting in color, high in reflective rate, non-poisonous, environment-friendly and safe to use.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an environment-friendly reflective coating. Background technique [0002] The main raw materials used in reflective materials include resins, pigments, glass beads, etc., and any raw material is very important to the performance of reflective products. Among them, the bonding resin must have good construction performance and excellent bonding ability. If there is no protective layer on the surface, the bonding resin must also be waterproof and washable. The surface resin requires good transparency. Ideal Refractive index, excellent weather resistance and stability, and the connection of each layer of resin must also have a good match, so as to meet the optical characteristics, use requirements and manufacturing process requirements of reflective material products; for pigments, high transparency is required properties, color stability, and good compatibility with resins. For gl...
