Environment-friendly nano fire-retardant coating

Abstract

The invention relates to an environment-friendly nano fire-retardant coating which can be used on the surface of flammable base material, and can reduce the surface flammability of the material to be coated and retard the rapid spread of the fire so as to improve the fire endurance of the material to be coated. The fire-retardant coating is prepared by acrylic resin, polyphosphoric acid amine, nano SiO2, pentaerythritol, butanol and titanium dioxide according to ratio of parts by weight. The components are adjusted to the most scientific and reasonable state, a little nano-material is added, therefore the related properties and partial technical indexes of the fire-retardant coating such as fire retardance, antirust property, waterproofness, levelling property and strength are improved, the cost is low, the coating is uniform and continuous, compact and wear-resisting, the tenacity, dyeing property, adhesiveness, fast-drying nature and certain gloss of the coating are improved; and the nanotechnology is effectively combined with the formula and process of the coating, therefore the product quality is improved.

Description

technical field

[0001] The invention relates to an environment-friendly coating, in particular to an environment-friendly paint that can be used on the surface of flammable substrates, can reduce the flammability of the surface of the material to be coated, retard the rapid spread of fire, and improve the fire resistance limit of the material to be coated. Type nano fire retardant coating. Background technique

[0002] Nano is the smallest unit of length measurement. The length of 1 nanometer is one millionth of a millimeter. Nanotechnology is within the length range of 1nm-100nm, directly using atoms, atomic groups, molecules, and molecules that make up various elements and substances. Group assembly of materials with specific functions or high-tech technologies with special performance products. Successful nanotechnology can be applied in various fields such as electronics, chemical industry, and military affairs, and all countries in the world are researching and develop...
