Problems solved by technology

[0003] Technical problems to be solved: Conventional architectural coatings have poor waterproof and heat resistance properties. After being painted on buildings for a long time, due to moisture erosion and high temperature exposure, the coatings will foam and fall off. , so there is a need for a new architectural coating with good waterproof and heat-resistant effect and its preparation method

Abstract

The invention discloses a water-resistant heat-resistant architectural paint which is prepared from the following raw materials in parts by weight: 14-19 parts of phenol aldehyde resin, 6-12 parts of polyformaldehyde resin, 3-6 parts of polyvinylidene fluoride resin, 4-7 parts of epoxy butane, 5-13 parts of silicone-acrylic emulsion and 4-9 parts of aluminum tripolyphosphate. The preparation method comprises the following steps: mixing, shearing, ball milling and the like. The prepared paint has excellent water resistance and heat resistance, and does not have the condition of peeling or blistering after long-time usage.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a building coating and a preparation method thereof, in particular to a waterproof and heat-resistant building coating and a preparation method thereof. Background technique [0002] Coating refers to a general term for a class of materials that can form a tough protective film when applied to the surface of an object. Generally, the coatings used for interior walls, exterior walls, ceilings and floors of buildings are called architectural coatings. Architectural coatings are an important category within coatings. According to the type of base material, it can be divided into organic coatings, inorganic coatings, and organic-inorganic composite coatings. Due to the different solvents used, organic coatings are divided into two types: organic solvent-based coatings and organic water-based (including water-emulsion and water-soluble) coatings. Common paints in life are generally ...
