Problems solved by technology

3. Most anti-corrosion coatings will have special functions. For example, the coatings used on ships need to add toxic substances such as heavy metals to kill algae. Long-term exposure will cause great harm to human health.
4. The paint with solvent toluene is irritating to the skin and mucous membranes, and has an anesthetic effect on the central nervous system; it is seriously harmful to the environment and can cause pollution to the air, water environment and water sources
The release of these volatile organic compounds reaches a certain peak in 3-6 months, causing serious damage to human health

Abstract

The invention belongs to the field of coatings and particularly relates to an ecological degradable environment-friendly coating, composed of component A and component B according to a weight ratio of 5:1; the component A includes the following ingredients according to percent by weight: 20-35% of resin, 3-6% of an active diluent, 12-15% of calcium carbide, 10-15% of nano titanium dioxide, 10-16% of attapulgite, 12-20% of diatomite, 0.75-2.2% of an aid, 4-15% of a pigment, adding up to 100% by weight; the component B includes the following ingredients according to percent by weight: 99.3-99.7% of a curing agent and 0.3-0.7% of a foaming agent, adding up to 100% by weight. The materials, the nano titanium dioxide, calcium carbide, foaming agent, attapulgite and diatomite, are added to the coating to impart quadruple ecological degradation, and the prepared coating is environment-friendly and safe.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an ecologically degradable and environment-friendly coating. Background technique [0002] As a product closely related to people's life, paint is related to everyone's physical and mental health, and everyone is in contact with paint all the time. The toxicity of coatings is mainly manifested in: 1. Glycol ethers and their ester solvent coatings directly have a lethal effect on the human body. If they are exposed to for a long time, it will seriously damage the blood and lymph, and even more seriously, it will cause huge damage to the reproductive system. harm. 2. Amino paint has a pungent smell and is very harmful to human health; the construction site should have good ventilation facilities, and painters should wear glasses, gloves, masks, etc. to avoid skin contact and inhalation of paint mist. Fireworks are strictly prohibited on the construction site. 3. Most anti-cor...
