Abstract

The invention discloses a processing method for a diatomite plate. The processing method is characterized by including the steps of preparing materials, wherein natural diatomite, cement, kaolin, attapulgite, sepiolite mine powder, bentonite, expanded perlite powder, natural linen fibers, hydroxypropyl methylcellulose powder, emulsified silicone oil and water are stirred according to the amount, and evenly-mixed material slurry is prepared; forming, wherein the prepared material slurry is subjected to water filtering and dewatered in a fourdrinier-wire salvaging machine, and a blank is prepared; cutting and drying, wherein the blank is cut into a plate with the size of 1,200 mm*600 mm to be dried, cooling is carried out at the room temperature, and the diatomite base plate is prepared. The method is scientific and reasonable, the weight of the made diatomite plate is light, cutting is easy to achieve, indoor decoration and indoor construction are convenient, and indoor environmental protection can be achieved.

Description

technical field [0001] The invention belongs to the technical field of interior decoration materials, and relates to a diatomite board and a manufacturing method thereof. Background technique [0002] At present, various decorative materials made of diatomite as the main raw material have increasingly become the main trend of the development of modern interior decoration materials, and have been widely used in various interior decoration and decoration. Modern healthy life brings security. Chinese Patent Publication No.: CN103880349A discloses a method for manufacturing a diatomite cement board. The board manufactured by this method is not only heavy in weight, but also too hard to cut for construction. Chinese Patent Publication No.: CN105130331A discloses the component configuration of a lightweight diatomite board, and does not involve the production process. So far, there are no literature reports and practical applications on the detailed composition configuration and...
