Problems solved by technology

Since the suspension is prepared with a single component attapulgite, the performance is still not very satisfactory, and the cost is high due to the addition of nano-sized particles
[0012] Although the above-mentioned prior art discloses some paint suspending agents, which can meet certain needs, there are still certain defects in these paint suspending agents: they cannot be used for both alcohol and water, and most of them need to be triggered with water before they can be used. , which limits the scope of application, and the production method of the coating suspending agent is cumbersome, which is not suitable for large-scale industrial application

Embodiment 1

[0033] The present embodiment relates to a kind of production method of environmental protection dual-purpose type paint suspending agent, is made up of following steps:

[0034] Step 1, stir 20kg bentonite, 1kg sodium carbonate and 6kg water evenly, then crush the pair of rolls twice, stack them for 17 hours, control the weight percentage water content of the pair of roll sheets to be 33%, and obtain modified bentonite;

[0035] Step 2, mixing the modified bentonite with 75kg attapulgite clay, 4kg lithium carbonate and 15kg water, crushing the pair of rolls twice, stacking for 36 hours, controlling the weight percentage water content of the pair of roll sheets to be 45%;

[0036] Step 3: Air-dry or dry the product obtained in Step 2 naturally, crush it, and grind it to a solid powder of 150 meshes.

Embodiment 2

[0038] The present embodiment relates to a kind of production method of environmental protection dual-purpose type paint suspending agent, is made up of following steps:

[0039]Step 1: Stir 10kg of bentonite, 1.5kg of sodium carbonate and 5kg of water evenly, then crush the pair of rolls twice, stack them for 24 hours, control the weight percentage water content of the pair of roll sheets to be 30%, and obtain modified bentonite;

[0040] Step 2, mixing the modified bentonite with 65kg attapulgite clay, 5kg lithium carbonate and 10kg water, crushing the pair of rolls twice, stacking them for 24 hours, controlling the weight percentage water content of the pair of roll sheets to be 50%;

[0041] Step 3, the product obtained in step 2 is air-dried or dried naturally, crushed, and ground to 200-mesh solid powder.

Embodiment 3

[0043] The present embodiment relates to a kind of production method of environmental protection dual-purpose type paint suspending agent, is made up of following steps:

[0044] Step 1: Stir 30kg of bentonite, 0.5kg of sodium carbonate and 4kg of water evenly, then crush the pair of rolls twice, stack them for 10 hours, control the weight percentage water content of the pair of roll sheets to be 35%, and obtain modified bentonite;

[0045] Step 2, mixing the modified bentonite with 85kg attapulgite clay, 3kg lithium carbonate and 13kg water, crushing the pair of rolls twice, stacking for 48 hours, and controlling the weight percentage water content of the pair of roll sheets to be 40%;

[0046] Step 3, the product obtained in step 2 is air-dried or dried naturally, crushed, and ground to 300-mesh solid powder.

Abstract

The invention relates to a production method of an environment-friendly dual-purpose coating suspending agent. The method comprises the following steps that 1, bentonite, sodium carbonate and water are stirred evenly, then roller-crushing and stacking are performed, the water content of a rolled-crushed piece is controlled to be 30-35% by weight, and modified bontonite is obtained; 2, the modified bontonite, attapulgite, lithium carbonate and water are mixed evenly, roller-crushing and stacking are performed, and the water content of the rolled-crushed piece is controlled to be 40-50% by weight; and 3, the product obtained in the second step is naturally aired or dried, crushed and ground into powder, and the environment-friendly dual-purpose coating suspending agent is obtained. The sodium bentonite is obtained by modifying the bentonite through the sodium carbonate firstly, then the sodium bentonite and the attapulgite are modified through the lithium carbonate, and the environment-friendly dual-purpose coating suspending agent containing no organic additive is obtained and can be directly used for water-based and alcohol-based coatings. Meanwhile, the production method is simple and suitable for large-scale industrial application.

Description

technical field [0001] The invention relates to the field of paint suspending agents, in particular to a production method of an environmentally friendly dual-purpose paint suspending agent. Background technique [0002] Coating is the most effective measure to solve the sand sticking on the surface of castings and improve the surface quality of castings. Alcohol-based quick-drying coatings have the advantages of shortening the construction time and improving the production efficiency of castings, and have occupied the main share of the coatings market for a long time. [0003] The suspension stabilizer is a material that makes the coating have suspension stability and proper rheological properties. The addition of the suspension stabilizer should greatly improve the overall performance of the coating. [0004] The suspending agent for alcohol-based casting coatings has experienced the development process from sodium-based bentonite to organic bentonite. Na-based bentonite ...
