Abstract

The invention discloses an insulating fireproof coating for appliances and a preparation method thereof, and relates to the technical field of coating. The coating is prepared from the following raw materials in parts by weight: 55-65 parts of modified acrylic resin, 40-45 parts of organic silicon modified epoxy resin, 30-40 parts of acrylic emulsion, 30-40 parts of insulating additive, 20-25 parts of modified hollow glass beads, 10-20 parts of adjuvant and 65-75 parts of water. After being used on an appliance surface, the coating has strong binding performance, cannot be cracked in long-term use, can form a hydrophobic molecular layer on the appliance surface, and has the effects of preventing water and fire, insulating and resisting abrasion.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an insulating fireproof coating for electrical appliances and a preparation method thereof. Background technique [0002] Applying insulating paint on the surface of electrical appliances is a safety measure that uses non-conductive substances to isolate or wrap the charged body to protect against electric shock. Good insulation is the most basic and most reliable means to ensure the safe operation of household appliances and lines and prevent personal electric shock accidents. However, the existing coatings have poor high temperature resistance and water resistance, and are prone to cracking after long-term use. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an insulating fireproof coating for electrical appliances and a preparation method thereof. After the coating is used on the surface of the electrical appliance, it has strong bindin...
