Preparation method for diatomite calcium plastic composite plate

Abstract

The present invention proposes a preparation method of diatomite calcium plastic composite board, the steps are as follows: (1) Prepare the upper board and the lower board: ① prepare raw materials in parts by weight as follows: PVC resin, diatomite, calcium carbonate , wood powder, 1010 antioxidant, glycerin, hydroxymethyl cellulose, ceramic particles, methyl salicylate, silicon carbide; The thickness of the plate is twice the thickness of the lower plate; ③ dig out an adsorption cavity on the lower surface of the upper plate; ④ frost the lower surface of the upper plate and the inner wall of the adsorption cavity; ⑤ fill the adsorption cavity with activated carbon, and Coating a layer of adhesive on the lower surface of the upper plate ⑥ Pressing the lower plate on the upper plate and fixing it into shape, the prepared plate has a good fireproof and waterproof effect, and can effectively absorb formaldehyde at the same time, with good adsorption.

Description

technical field [0001] The invention relates to the technical field of civil furniture and decorative boards, in particular to a preparation method of diatomite calcium plastic composite boards. Background technique [0002] With the continuous development of society and the continuous progress of science and technology, people's living standards and quality requirements are also constantly improving. As we all know, in recent years, the winter heating method has gradually changed from the traditional casting radiator heating method to a diversified heating method. For example: the "geothermal" heating method of aluminum-plastic pipes, the air-conditioning hot air heating method, the electric heating method, and stainless steel or aluminum alloy heaters, among which the "geothermal" heating method of aluminum-plastic pipes is the most popular. The above-mentioned "geothermal" heating method has indeed relatively beautified the indoor environment and relatively improved the ...

Problems solved by technology

[0003] ① Huge waste of resources; traditional heating takes up valuable land resources to build boiler rooms, coal storage yards, and slag discharge yards. Since water is used as the heat transfer medium, a large amount of increasingly scarce water resources are wasted; the heating pipeline route is long, Running, popping, dripping, and leaking are inevitable, which will cause waste of hot water

[0004] ② Serious pollution; using traditional heating, coal and slag will cause environmental pollution during transportation and storage; in addition, necessary equipment in the boiler operation process such as: coal loading machine, grate machine, slag remover, induced draft fan, blower, circulation Pumps, etc., will emit noise during operation and will also pollute the environment; in addition, lubricating oil during mechanical operation and cleaning agents used during maintenance will cause ground and drainage pollution

[0005] ③Passive heating: The traditional heating method is passive heating. As long as the heating fee for the whole winter is paid, how to use it is up to the user. Cause energy waste; In addition, if the heating period is not reached or the heating period has passed, even if you feel cold, you have to endure it or use other auxiliary heating supplements in an emergency, and the heating method lacks humanization; There is no way to solve this kind of problem in water heating and heating, and the heating fee still needs to be paid, and the individual has no autonomy, so it costs a lot of money; traditional heating cannot be controlled by room, and both rooms where no one is active and the room where people are occupied have to be heated

[0006] ④Inconvenient installation and maintenance; annual inspection and maintenance of traditional heating boilers and mechanical equipment is essential; the rupture and corrosion of outdoor heating pipes and radiators need to be repaired and replaced, which will consume a lot of manpower and material resources; traditional heating The inner pipes need to be cleaned in 3 to 5 years, maintained in 5 to 8 years, and the boiler needs to be replaced in 15 years; the outer pipes also need to be replaced in stages; in traditional geothermal heating, the geothermal layer is laid in a wet method, which consumes a lot of cement to increase the floor slab heavy load, the installation work is complicated and time-consuming, and the quality is difficult to guarantee
