Embodiment Construction

[0010] 1. Diatomite collection and processing: select pure diatomite, after mining, dry, dry and pulverize, after pulverization, pass through a 100-mesh sieve to become diatomite powder.

[0011] 2. Preparation of foamed cement powder: choose No. 42.5 ordinary Portland cement as raw material, add 80 kg of water to 100 kg of raw material, then add 0.5 kg of manganese dioxide, 0.5 kg of dry surfactant, and an oxygen content of 23% Add 10 kg of hydrogen peroxide, add the above raw materials into the mixer and stir evenly, pour into the mold, foam and solidify, keep healthy at natural temperature for 5 days, dry for 5 days, then cut into flakes, and use a roller compactor to roll into powder. 100 mesh sieve to become foamed cement powder.

[0012] 3. Bamboo short fiber preparation: cut bamboo stalks into 1 cm long segments, add them to caustic soda solution with a mass percentage of 40%, boil them thoroughly, remove them, wash them with water, dry them after washing, and add them ...

Abstract

The invention relates to a preparation method of a composite diatom ooze wall coating material. The method comprises the following steps: collecting and processing kieselguhr; preparing foamed cement powder; preparing short bamboo fibers; and preparing the composite diatom ooze wall coating material. The wall coating material is prepared by compounding the kieselguhr, the foamed cement powder and the short bamboo fibers, wherein the foamed cement powder has the porosity, so that the foamed cement powder has the performance of adsorbing particles in air; the short bamboo fibers have the anti-cracking performance, so that the short bamboo fibers can perform a toughening function and can be used for absorbing and regulating the air moisture at the same time. Thus, compared with the existing pure diatom ooze, the composite diatom ooze wall coating material provided by the invention is high in strength, strong in air moisture regulating ability, low in cost and easy in material selection, and can generate the effect of natural textures. As a result, the method provided by the invention is suitable for being applied to the preparation of the composite wall coating material taking the diatom ooze as a main body.

Description

technical field [0001] The invention proposes a material for wall coating in the field of building materials, in particular a method for preparing a composite diatom mud wall coating material. Background technique [0002] At present, the use of seaweed mud as a wall coating material has been widely used, because seaweed mud has a certain effect of breathing and humidity control, sound absorption and dryness reduction, and heat insulation; the texture is thick, the texture pattern is natural and simple, and it will not fade or pulverize for 30 years. , slag, peeling; healthy and environmentally friendly, zero VOC paint, reduce light pollution. However, when seaweed mud is used alone, the air permeability, moisture absorption and strength-related properties cannot meet the optimal requirements, especially the selection range of seaweed mud suitable for wall coating applications is small, so the cost is relatively high. These factors directly affect the performance of seaweed...
