Problems solved by technology

The invention uses a healthy solvent that is harmless to the human body, so that the produced alkyd resin is completely free from benzene harmful substances, which greatly improves the health and safety of the product; it can give people a fresh and comfortable feeling during use, even for those who are sensitive The crowd can also breathe freely, giving people all-round enjoyment. However, the coating does not have the function of antibacterial and sterilizing, but the solvent it uses is harmless to the human body. It cannot be used in environments with high antibacterial requirements such as hospitals and biological laboratories. competent

Abstract

The invention provides a novel water-based alkyd resin coating comprising the following components in parts by weight: 42-66 parts of alkyd resin, 0.3-1 part of silver-loaded hydroxyapatite, 0.4-0.9 part of a dispersant, 5-8 parts of a peppermint extract, 1-2 parts of a compatilizer, 5-26 part of a pigment, 4-14 parts of a filler, 5-9 parts of a solvent, 0.1-0.5 part of a dryer, 0.1-0.2 part of a leveling agent and 12-16 parts of water. The invention also provides a preparation method of the water-based alkyd resin coating. The water-based alkyd resin coating provided by the invention is relatively good in antibacterial property and is suitable for environments with relatively high antibacterial requirements.

Description

Technical field: [0001] The invention relates to a kind of architectural paint, in particular to a novel water-based alkyd resin paint and a preparation method thereof. Background technique: [0002] Alkyd resin coating, the English name is alkyd resin coating, is a synthetic resin coating with alkyd resin as the main film-forming substance. Alkyd resin is a resin formed by the reaction of fatty acid (or its corresponding vegetable oil), dibasic acid and polyol. Polyols commonly used in the production of alkyd resins include glycerin, pentaerythritol, trimethylolpropane, etc.; commonly used dibasic acids include phthalic anhydride (ie, phthalic anhydride), isophthalic acid, etc. Alkyd resin coatings have the characteristics of weather resistance, good adhesion, etc., and are relatively convenient to construct. They can be formulated with other resins to form a variety of self-drying or drying enamel, primer, topcoat and varnish with different properties. They are widely use...
