preparation example Construction

[0029] A preparation process of plant fiber diatom mud comprises the following process steps.

[0030] Step 1: Accurately weigh the materials in the formula according to the weight ratio.

[0031] Step 2: Automatically add materials with a total weight of more than 5 kg into the double-helix stirring tank with the elevator in turn, and directly add materials below 5 kg into the stirring tank to avoid loss of the elevator, and then close the upper hatch.

[0032] Step 3: Start the stirring tank at a speed of 100-500 rpm, and stir for 50-60 minutes.

[0033] Step 4: Open the lower hatch, the stirred diatom ooze is filtered through a 60-120 mesh vibrating screen, and then enters the hopper of the automatic packaging machine to start packaging.

Embodiment 1

[0035] 30% diatomite, 10% plant fiber powder, 10% kaolin, 2% bentonite; 5% anion powder; 5% titanium dioxide; 5% amedadone; 10% calcite powder; 15% calcium ash; Latex powder 7%; powder defoamer 0.2%; powder wetting agent 0.2%; powder antifungal agent 0.2%; hydroxypropyl methylcellulose 0.4%.

[0036] The raw materials in the formula of Example 1 above were mixed for 1 hour at a speed of 200 rpm through a twin-screw mixer, then passed through a 110-mesh sieve, and packaged to obtain plant fiber diatom mud.

[0037] The construction process is as follows: add the prepared plant fiber diatom mud into clean water according to the proportion, stir well, let it stand for half an hour, then make up water, adjust to a suitable consistency and stir for 5 minutes, and then filter it with a fine sieve. Carry out batch scraping or bomb coating construction.

Embodiment 2

[0039] 20% diatomite; 30% plant fiber powder, 8% kaolin; 4% bentonite; 5% negative ion powder; 3% titanium dioxide; Latex powder 5%; powder defoamer 0.2%; powder wetting agent 0.2%; powder antifungal agent 0.2%; hydroxypropyl methylcellulose 1.4%.

[0040] The raw materials in the formula of Example 1 above were mixed for 1 hour at a speed of 300 rpm through a twin-screw mixer, then passed through a 90-mesh sieve, and packaged to obtain plant fiber diatom mud.

[0041] The construction process is as follows: add the prepared plant fiber diatom mud into clean water in proportion and stir well, let it stand for half an hour, then make up water, adjust to a suitable consistency and stir for 5 minutes before batch scraping or bomb coating construction.

Abstract

The invention provides plant fiber diatom ooze and a preparation process thereof. The plant fiber diatom ooze comprises the following components in mass ratio: 10-40% of diatomite, 10-50% of plant fiber powder, 5-20% of kaoline, 1-5% of bentonite, 3-10% of anion powder, 3-10% of titanium dioxide, 3-10% of imidoketone, 5-25% of calcite powder, 5-25% of ash calcium, 5-25% of redispersible latex powder, 0.2-0.5% of powder defoaming agent, 0.2-0.5% of powder wetting agent, 0.2-0.5% of powder mildew preventive and 0.2-5% of hydroxypropyl methyl cellulose. By utilizing techniques of sorting, mixing, screening and the like, the produced diatom ooze has excellent elasticity and sound-absorption heat-insulating performance, soft and comfortable touching sense, and crack resistance and mildew resistance, and the produced diatom ooze is an indoor decoration wall material which has excellent combination performance integrating functionality, practicability and decorative performance.

Description

technical field [0001] The invention relates to a composite material, in particular to a plant fiber diatom mud and a preparation process thereof. Background technique [0002] Diatom mud is a kind of interior decoration wall material with diatomite as the main raw material. its organizational structure It is a porous "molecular sieve" with strong physical adsorption performance and ion exchange performance. With the wide application of diatom mud, the market demand is increasing, but diatomite is a limited mineral resource. In order to save diatomite resources, pure natural plant fibers are used to replace part of diatomite. The breathing characteristics are similar to diatomite, and it is easy to obtain and the resources are endless. It can not only save diatomite resources, but also improve the crack resistance, flexibility, air permeability and thermal insulation of diatom mud. It is an ideal s Choice. [0003] At present, the plant fiber diatom mud on the market only...
