preparation example Construction

[0041] The preparation method of the above-mentioned diatomite board based on two or three grades of diatomite comprises the following steps:

[0042] Step 1, batching according to the proportioning ratio, stirring and mixing evenly to obtain the mixed material;

[0043] Among them, the stirring speed is generally 1200-1500r / min, and the time is 10-20min;

[0044]Step 2. After diluting the mixed material with water, stir evenly, pave and shape, remove moisture under negative pressure, and after heat balance, stand and solidify to obtain a slab;

[0045] Among them, the stirring speed is generally 1100 ~ 1300r / min, the time is 5 ~ 10min, the removal of moisture is generally under vacuum -0.05 ~ -0.1MPa for 10 ~ 60min, and the water content reaches 6 ~ 10%; the heat balance is preferably maintained at room temperature 5-6 days; static curing time is generally more than 24h;

[0046] Step 3, forming the slab by hot pressing to obtain a rough slab;

[0047] The pressure of hot ...

Abstract

The invention relates to a kieselguhr board based on two to three-level kieselguhr and a preparation method thereof, belongs to the technical field of building materials and solves the technical problem that an application range of kieselguhr boards in the prior art is limited. The kieselguhr board disclosed by the invention is prepared from 30 to 45 weight parts of two to three-level kieselguhr, 10 to 15 weight parts of plant fiber, 3 to 5 weight parts of bisphenol A, 25 to 30 weight parts of expansible polystyrene, 5 to 8 weight parts of foaming agent and 0.1 to 0.5 weight part of kieselguhr white carbon black loaded with nano titanium dioxide compound photocatalytic material. The kieselguhr board not only has necessary breaking strength, but also has light weight, heat insulation, water and moisture resistance and functions of automatically adjusting indoor humidity, adsorbing harmful gas, keeping indoor cleaning and the like, can obviously improve an indoor human settlement environment and improve crowd living quality and is suitable for being used as building indoor ceilings, decoration boards, light partition boards and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a diatomite board based on secondary and tertiary diatomite and a preparation method thereof. Background technique [0002] With the rapid development of the national economy and the continuous improvement of living standards, urban and rural residents have put forward higher and higher requirements for the quality of living environment, especially the comfort and safety of living space. Now in the market, the commonly used decoration boards are wood boards and medium and high density fiberboards. Because of its high price, difficult maintenance, and easy deformation, planks should not be too cold or too hot, nor too wet or too dry, so they cannot be used universally. Medium and high-density fiberboards are widely used due to their excellent physical properties, but ordinary medium and high-density fiberboards have many defects, such as the ability to rele...
