Problems solved by technology

[0003] At present, my country's amino drying coatings occupy an important position in light industry, home appliances, automobiles, machinery and other industries. However, traditional amino drying coatings are basically solvent-based. The volatilization of a large number of toxic solvents during the drying process not only It deteriorates the environment, is not conducive to environmental protection, causes serious pollution to the atmosphere, and also increases fire hazards.

Embodiment Construction

[0008] The present invention is described further below, and preferred embodiment of the present invention is: the water-soluble amino coating described in the present embodiment, at first makes water-soluble amino resin by proportioning, described water-soluble amino resin is made of following components by traditional process Production: Formaldehyde (37%) 50%, Melamine 14%, Polyethylene Glycol 4%, Urea 3%, Methanol 24%, Oxalic Acid 2%, Sodium Hydroxide (30%) 3%.

[0009] Take 50% of the above-mentioned amino resin, then add 13% of titanium dioxide, 0.7% of polycarboxylate dispersant, 2% of ethylene glycol monobutyl ether, 0.07% of alkylphenol polyoxyethylene (10) ether, 3% of propylene glycol, poly Dimethyl siloxane 0.05%, deionized water 31.18%, and then according to the traditional process to produce a water-soluble amino coating with no shrinkage cavity, no bubbles and excellent performance.

Abstract

The invention discloses a water-soluble amino paint, which consists of the following components in percentage by weight: 50-56% of water soluble amino resin, 12-18% of titanium dioxide, 0.5-1.0% of polycarboxylate dispersing agent, 2-5% of ethylene glycol-butyl ether, 0.05-1.0% of alkyl phenol polyoxyethylene (10), 1-3% of propylene glycol, 0.05-1.0% of polydimethylsiloxane and 20-45% of de-ionized water. The paint disclosed by the invention is good in construction performance, applicable to many construction methods, bright and smooth in coating appearance, free from shrinkage, bubble and other defects, and excellent in performance; and the paint is free from generation and discharge of methanol in the construction process, so the construction environment is protected and the operation condition is improved, so as to really realize low-toxic and low-pollution production and construction environment.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a water-soluble amino paint. Background technique [0002] In the 1930s, methanol-etherified amino resins had begun to be used in the fabric finishing industry. In the 1960s, in order to reduce environmental pollution and save energy from organic solvents in coating construction, water-based coatings and high-solid coatings, methanol ether, were developed. The application of the modified amino resin as a crosslinking agent for coatings has been expanded, and serialized products have appeared. Among them, the amino drying coating made of amino resin and alkyd resin is currently one of the most widely used coatings in the field of industrial coating. The coating film formed by it has high hardness and gloss, and its acid and alkali resistance Performance, water resistance and weather resistance are significantly better than alkyd coatings. [0003] At present, my country's amino d...
