Embodiment 1

[0018] An alcohol-based coating for cast iron stoves, comprising the following raw materials in parts by weight: 30 parts of epoxy resin, 15 parts of glass fiber, 4 parts of borax, 3 parts of nano silicon dioxide, 10 parts of modified starch, 30 parts of pentaerythritol and 30 parts of isoamyl alcohol.

[0019] Put pentaerythritol and glass fiber in ultrasonic wave to disperse evenly to obtain dispersion A, place borax, nano-silica and isoamyl alcohol in ultrasonic wave to disperse evenly to obtain dispersion B, add dispersion A in turn under stirring condition Epoxy resin, dispersion B and binder, mixed evenly to obtain alcohol-based paint.

[0020] The modified starch is obtained through the following steps: mix the starch with water, heat to 60-80°C, add citric acid after mixing well, cool down to 30-40°C, keep the temperature at 30-40°C, add α- Amylase reacts for 30-60 minutes under stirring conditions, then adds acrylic acid and polyglycerin fatty acid ester, and stirs t...

Abstract

The invention discloses an alcohol-based coating for a cast iron stove. The coating comprises, by weight, 30-40 parts of epoxy resin, 10-15 parts of glass fiber, 4-8 parts of borax, 1-3 parts of nanosilicon dioxide, 10-15 parts of binder, 30-40 parts of pentaerythritol and 30-40 parts of isoamyl alcohol. According to the alcohol-based coating, pentaerythritol and isoamyl alcohol are used as mainraw materials, borax and nano silicon dioxide are added to improve the heat resistance of the coating, glass fiber is added to improve the strength of the coating and prevent sand sticking, epoxy resin is added, and the binder is added to improve the fluidity and viscosity of the coating.

Description

technical field [0001] The invention relates to an alcohol-based coating for cast iron stoves and a preparation method thereof, belonging to the technical field of cast iron product processing. Background technique [0002] Coating is the most effective measure to solve the sand sticking on the surface of castings and improve the surface quality of castings. Alcohol-based coatings have been widely used in my country due to their advantages such as fast drying speed, high production efficiency, low cost, short production cycle and wide application range. . The annual consumption can reach 30,000 to 40,000 tons, and its usage is showing an increasing trend, and the market prospect is broad. However, there are many problems in the use of alcohol-based coatings produced by my country, such as poor suspension, poor advection, volatile, refractory aggregate sinking to form "dead sediment" and so on. Therefore, a kind of alcohol base paint for cast iron stove and its preparation m...
