Preparation method of special formaldehyde-removing paint for furniture

Abstract

The invention discloses a preparation method of a special formaldehyde-removing paint for furniture. The method comprises the steps of mixing polyalkylene imide, polypropylene glycol and a helical carbon fiber at the ratio and then preparing a formaldehyde trapping agent; mixing with water for ultrasonic dispersion, carrying out vacuum drying on a rotary evaporator and crushing the mixture into 500 meshes; and finally carrying out mix dispersion on the product and a wood coating, painting or spraying the paint on the surface of the furniture through a spray gun and drying and polishing. The special formaldehyde-removing paint for the furniture is excellent in purification effect due to the fact that the helical carbon fiber is low in molecular weight, relatively weak in polarity and over-large in specific surface area; the formaldehyde trapping agent is evenly dispersed into the paint, and paved on the surface of the furniture, so that the special formaldehyde-removing paint is large in absorption acting surface, short in absorption time, good in absorption effect and convenient to use.

Description

technical field [0001] The invention relates to the field of formaldehyde-removing household products, in particular to a preparation method of a special formaldehyde-removing coating for furniture. Background technique [0002] With the improvement of people's living standards, home decoration is becoming more and more luxurious. The use of a large number of decoration materials brings convenience to people, but also causes the continuous deterioration of indoor air quality, and the harm to human body has become a hot issue of concern. At present, forestry resources are increasingly tense, and the government actively calls for the use of wood-based panels to replace solid wood. Although wood-based panels are cheap and versatile, they are the main raw materials for the production of wooden furniture and interior decoration. However, wood-based panels need to use a lot of glue during use. The glue used is generally cheap urea-formaldehyde resin glue. Urea-formaldehyde resin ...

Problems solved by technology

[0003] The most widely used and most stable indoor pollutant purification method for a long time is the activated carbon physical adsorption method. However, in the prior art, a single adsorbent is used, which is often a pack or a box of adsorbents. The surface is small, the adsorption time is long, the adsorption effect is not good, and it is inconvenient to use

Moreover, formaldehyde has a low molecular weight and strong polarity, so it is difficult to physically remove it through activated carbon, and the purification effect is poor.

Although there are currently some modified activated carbons on the market for purifying formaldehyde, such as sodium thiosulfate, potassium permanganate and other modified activated carbon adsorbents, although the performance of ordinary activated carbon adsorbents can be improved by 1 to 2 times, but still up to Less than expected purification effect
