Gypsum plasterboard

Abstract

The present invention discloses a paper-surface gesso plate, which is made of the following components according to weight ratio: 40-50 percent of gesso powder, 0.5-5 percent of active carbon, 0.5-1 percent of corn amylum and 0.4-0.8 percent of paper pulp fibre. Each raw material after being matched together with water is put into a mixer for milling, and then is to be pressed into a mould; the molded gesso plate is to be dried after being cut; the gesso plate after being dried is to be made with the second cut; finally, the products are packed and stored in the warehouse. Because active carbon is added into the gesso plate, by the test and detection in the house decorated with the gesso plate, the result shows that each residual organic volatile brought from the indoor fitment and other decorative materials can be adsorbed effectively; the adsorbing effect is 2-5 times better than that of the gesso plate without added with the active carbon. Besides, the present invention has the long-term and persistent absorption function. The present can avoid the disadvantage to the body health by the deleterious volatile. The manufacturing process is simpler and the social and economical benefits are much greater.

Description

technical field [0001] The invention relates to a decorative material, in particular to a paper-faced gypsum board capable of absorbing harmful gases such as xylene and formaldehyde. Background technique [0002] Gypsum decorative board is a new type of interior decoration material introduced in the market in recent years. Because of its low cost and convenient use, it is widely used in the rapidly developing real estate industry and related decoration material industries. However, due to the common use of adhesives and preservatives containing toxic volatiles such as xylene and formaldehyde in the process of interior decoration and furniture production, the interior decoration and furniture slowly release residual volatiles such as xylene and formaldehyde for a long time. It poses a threat to human health, and even becomes an invisible killer of residents' health. Contents of the invention [0003] The invention aims to improve the existing interior decoration materials ...
