Formaldehyde-absorbing paint coating for interior walls and preparation method thereof

Abstract

The invention discloses a formaldehyde-absorbing paint coating for interior walls and a preparation method thereof. The formaldehyde-absorbing paint coating comprises the following raw materials in parts by weight: 30-40 parts of acrylic resin, 30-40 parts of cellulsic resin, 15-20 parts of rosin resin, 1-2 parts of dye, 2-3 parts of nanoscale titanium dioxide, 3-5 parts of sodium carboxymethyl cellulose, 5-7 parts of modified white carbon black, 2-3 parts of a dispersing agent, 1-2 parts of a defoaming agent, 3-5 parts of a formaldehyde absorbent, 1-2 parts of diphenyl polysiloxane and 10-15parts of a plant extracting solution. According to the invention, the plant extracting solution is added into the paint coating, natural properties of plants are utilized to have effects of formaldehyde absorption and anti-microbico, when the free formaldehyde in the plate is released outwards, the formaldehyde removal additive in the paint film is used for synergistic adsorption, so that the plant faint scent is added, the pungent smell of the paint is reduced, the physical and chemical properties of the paint are not influenced, and the formaldehyde removal additive and the paint have a synergistic effect to remove the free formaldehyde in various kinds of furniture.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, in particular to a formaldehyde-absorbing paint paint for interior walls and a preparation method thereof. Background technique [0002] Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called a paint. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. Formaldehyde is often produced during the production and processing of building materials, and a large amount of formaldehyde will be produced when painting furniture made of these boards. The main hazard of formaldehyde is the irritation to the skin and mucous membranes. When formaldehyde reaches a certa...

Problems solved by technology

[0004] 1. The existing paint has a strong smell, which is harmful to the human body. Many people have a strong sense of repulsion to the smell of paint. The smell of paint makes them feel dizzy, nauseous, vomiting, and irritable, which will not only affect their appetite but also seriously affect mental state;

[0005] 2. The existing paint has disadvantages such as unsatisfactory water resistance, abrasion resistance and weather resistance, poor fluidity, uneven dispersion, unsatisfactory spraying effect, and easy paint removal during use;

[0006] 3. In the existing paint preparation process, the preparation of plant extracts is complicated, and the preparation of plant extracts requires multiple infiltration, dissolution, extraction, filtration and other process steps, which requires a lot of equipment and high cost , at the same time, the operation intensity is high, which is not conducive to the large-scale production of paint coatings
