Problems solved by technology

[0003] Wood, boards, furniture, walls and other paints in the family room will contain formaldehyde, but what is even more frightening is that the release period of formaldehyde is generally three to fifteen years, resulting in the slow release of formaldehyde into the air to pollute the environment

Embodiment 1

[0021] The present embodiment provides a water-based paint, the weight ratio of which consists of: 25% water-based polyurethane resin, 34% talc powder of 1250 mesh, 10% bamboo charcoal powder with a particle size not greater than 100 microns, 8% additives, and 20% water.

[0022] Among them, the film-forming base material is selected from one-component water-based polyurethane, the filler is selected from 1250 mesh talcum powder, and the particle diameter of bamboo charcoal powder is not greater than 100 microns;

[0023] Preparation process: Stir all kinds of raw materials evenly, and prepare the paint.

[0024] Paint film performance index:

[0025] The appearance is smooth, the surface is dry for 0.5 hours, and the hard work is 8 hours. It is easy to polish. The formaldehyde adsorption rate is 96% (30d).

Embodiment 2

[0027] This embodiment provides a water-based paint, its composition by weight is: 30% of water-based styrene-acrylic emulsion, 10% of titanium dioxide, 18.5% of 1250 mesh talc powder, 8% of bamboo charcoal powder, 6% of additives, and 25% of water.

[0028] Preparation process: According to the general production process of architectural latex paint, it is mixed and ground to prepare a paint.

Embodiment 3

[0030] This embodiment provides a water-based paint, whose weight ratio is composed of: 45% water-based polyurethane resin, 20% titanium dioxide, 6% bamboo charcoal powder, 5% additives, and 22% water.

[0031] Preparation process: According to the general production process of architectural latex paint, it is mixed and ground to prepare a paint.

[0032] Paint film performance indicators: smooth appearance, 0.5h surface dry, 8h solid dry, contrast ratio 0.93, formaldehyde adsorption rate 98% (30d).

Abstract

The invention discloses an indoor decoration coating. The indoor decoration coating comprises the following components in percentage by weight: 20-60 percent of film-forming base stock, 0-30 percent of pigment, 0-40 percent of filler, 5-20 percent of bamboo carbon powder, 1-10 percent of assistant, and 10-30 percent of water. The bamboo carbon powder in the coating has good adsorption performance, and can adsorb formaldehyde released from the coating to effectively reduce the pollution of formaldehyde for long time, so that the indoor air can be improved.

Description

technical field [0001] The invention relates to a water-based paint, in particular to an environmentally friendly water-based paint for interior decoration. Background technique [0002] Many indoor decoration paints contain harmful substances such as formaldehyde, which is carcinogenic and teratogenic. Formaldehyde is a recognized allergen, is also one of the potential strong mutagen, and is also one of the risk factors leading to childhood leukemia. According to domestic medical journals and related literature reports, the hazards of indoor formaldehyde to human health can be summarized as stimulating, toxic and carcinogenic. [0003] Wood, boards, furniture, walls and other coatings in the family room will contain formaldehyde, but what is even more frightening is that the release period of formaldehyde is generally three to fifteen years, resulting in the slow release of formaldehyde into the air to pollute the environment. Therefore, how to improve the anti-formaldehy...
