Embodiment 1

[0050] a. Prepare precipitated calcium carbonate slurry:

[0051] a1. In the beaker 1, prepare a mixed solution according to the ratio of calcium carbide slag: water (mass ratio) = 1: 15, stir under the high-speed disperser to reach a uniform suspension state, and add 4mol / L dropwise at a speed of 600 rpm The hydrochloric acid, the ratio of hydrochloric acid and the above-mentioned calcium carbide slag dispersion slurry is 1: 1, keep the rotating speed of 800r / min at room temperature and react for 3 hours and then let it stand, then filter the reaction mixture, and get the clear calcium chloride solution for subsequent use.

[0052] a2. Put the calcium chloride solution taken out into the beaker 2, stir the calcium chloride solution at a high speed of 1000-1200r / min and add a sufficient amount of 0.1mol / L sodium carbonate solution until the reaction reaches the end point. Monitor the progress of the reaction with a pH meter, and finish the reaction when the pH value of the rea...

Embodiment 2

[0066] a. Prepare precipitated calcium carbonate slurry:

[0067] a1. In the beaker 1, prepare a mixed solution in the ratio of calcium carbide slag: water (mass ratio) = 1: 10, stir under a high-speed disperser to reach a uniform suspension state, and add 4mol / L dropwise at a speed of 600 rpm The hydrochloric acid, the ratio of hydrochloric acid and the above-mentioned calcium carbide slag dispersion slurry is 1: 1, keep the rotating speed of 800r / min at room temperature and react for 5 hours and then let it stand, then filter the reaction mixture, and get the clear calcium chloride solution for subsequent use.

[0068] a2. Put the calcium chloride solution taken out into the beaker 2, stir the calcium chloride solution at a high speed of 1000-1200r / min and add a sufficient amount of 0.1mol / L sodium carbonate solution until the reaction reaches the end point. Monitor the progress of the reaction with a pH meter, and finish the reaction when the pH value of the reaction mixtur...

Abstract

The invention relates to a water-based inner wall environmentally-friendly sealing compound using circulating resources, which comprises the following components in percentage by weight: 20 to 30 percent of precipitated calcium carbonate slurry, 20 to 30 percent of filler, 4 to 8 percent of synthetic high molecular emulsion, 20 to 30 percent of cellulose ether solution, 0.1 percent of preservative, 0.1 percent of antiseptic, 0.2 percent of de-foaming agent and the balance of water. The aim of the invention is to provide the efficient, low-cost and environmentally-friendly water-based inner wall environmentally-friendly sealing compound using the circulating resources and a method for preparing the same, which successfully solve the problems of requirements on special equipment, resource waste, non-environmentally-friendly prepared sealing compound containing soluble heavy metals, high VOC content and the like caused by the current preparation of precipitated calcium carbonate from industrial carbide slag.

Description

technical field [0001] The invention relates to the technical field of chemical building materials and preparation, in particular to a water-based interior wall environment-friendly putty using recycled resources and a preparation method thereof. Background technique [0002] With the continuous development of the construction industry, a large number of "putty" materials such as decorative plaster must be used in the decoration of buildings. The putty between the base layer and the coating layer plays an important role in bonding and transition, and also plays an important role in the texture decoration effect and water resistance and durability of the top coating. Since the putty layer is a material covered under the top coat, and the domestic market is flooded with low-quality and low-priced putty, many users associate cracking of the paint surface, powdering of the paint, peeling of the paint film, and efflorescence salt on the paint surface with the putty layer. The re...
