Embodiment 1

[0023] Preparation of expanded asbestos: 20kg of asbestos powder is placed in a microwave high-pressure reactor with a frequency of 2450MHz, a microwave power of 1000W, and a pressure of 8MPa. It is taken out after 3 minutes of microwave high-pressure treatment, and 1kg of coconut oil fatty acid diethanolamide is added. In the microwave high-pressure reactor, continue the microwave high-pressure treatment for 3 minutes, take it out after the treatment, and use a pulverizer to make 80-mesh micropowder when it is naturally cooled to below 55°C.

[0024] Preparation of water-dispersible paint: 40kg water-based acrylic resin, 21kg water-based alkyd resin, 7kg nano-calcium carbonate, 7kg expanded asbestos, 1.5kg sodium polyacrylate, 1kg dipropylene glycol butyl ether, 0.5kg water-based defoamer BYK-019 and Add 0.5kg of water-based leveling agent BYK-380N into the mixer, add water to adjust the solid content to 40%, and mix at 800r / min for 15min.

Embodiment 2

[0026] The water-based defoamer BYK-019 in Example 1 was replaced by the water-based defoamer BYK-024, and the rest were the same as in Example 1.

Embodiment 3

[0028] The coconut oil fatty acid diglycolyl consumption in embodiment 1 is replaced by 1.1kg by 1kg, and all the other are with embodiment 1.

Abstract

The invention discloses a water-dispersible paint for polymer products in coal mines, and relates to the technical field of water-dispersible paint. The invention uses water-based acrylic resin and water-based alkyd resin as film-forming resins, and combines them with various functional additives A water-dispersible paint is obtained; the prepared paint uses water as a diluent, which has high safety in use, and the paint can form a dense protective film on the surface of the product after being sprayed on the polymer product, and the formation of the protective film can It endows polymer products with excellent flame retardant and antistatic properties, so as to meet the use requirements of the coal mine underground environment.

Description

Technical field: [0001] The invention relates to the technical field of water-dispersible paints, in particular to a water-dispersible paint for underground coal mine polymer products. Background technique: [0002] Coal mine fires are one of the five major disasters in mines. Coal itself is a large and ubiquitous combustible substance in coal mines; secondly, a large amount of coal ash, gas, and pit logs, electromechanical equipment, and explosives produced during the production process Substances such as fuel and oil are flammable, and their existence is the basic element for a fire. [0003] Coal mine underground polymer products refer to products processed from high molecular polymers used in coal mines. Polymer products have potential safety hazards of static electricity during long-term use in the complex environment of coal mines, which can easily cause fires. Therefore, in order to improve the safety of use, people will spray paints with flame-retardant and antistat...
