Embodiment 1

[0021] Take 800 g of ground calcium carbonate powder of 1000 mesh, 100 g of hydroxypropyl methylcellulose, 150 g of latex powder, and 10 g of polyether modified silicone oil respectively, and set aside. Add 800g of 1000-mesh ground calcium carbonate powder into a gravity-free twin-shaft mixer, stir and preheat at 50°C for 5 minutes; then add 100g of hydroxypropyl methylcellulose and 150g of latex powder, Stir at low temperature for 8 minutes; finally add 10g of polyether modified silicone oil, stir at 40°C for 8 minutes, stop heating, continue stirring, and reach room temperature to obtain the product.

Embodiment 2

[0023] Take 90kg of heavy calcium carbonate powder of 1100 meshes, 12kg of hydroxypropyl methylcellulose, 20kg of latex powder, and 2kg of polyether modified silicone oil, respectively, and set them aside. Add 90kg of 1100-mesh ground calcium carbonate powder into a gravity-free twin-shaft mixer and stir at a temperature of 55°C to preheat for 8 minutes; then add 12kg of hydroxypropyl methylcellulose and 20kg of latex powder, Stir at low temperature for 12 minutes; finally add 2kg of polyether modified silicone oil, stir at 45°C for 9 minutes, stop heating, continue stirring until normal temperature, and get calcium carbonate putty powder.

[0024] Example 2

[0025] Take 100kg of heavy calcium carbonate powder of 1200 meshes, 15kg of hydroxypropyl methylcellulose, 30kg of latex powder, and 3kg of polyether modified silicone oil respectively, and set them aside. Add 100kg of 1200-mesh ground calcium carbonate powder into a gravity-free twin-shaft mixer and stir at a temperatu...

Abstract

The invention discloses calcium carbonate putty powder and a preparing method thereof. The calcium carbonate putty powder is prepared from, by weight, 80-100 parts of 1000-1200-mesh heavy calcium carbonate powder, 10-15 parts of hydroxy propyl methyl cellulose, 15-30 parts of latex powder and 1-3 parts of polyether modified silicon oil. By controlling the temperature and raw material adding programs in the stirring and mixing processes, the produced calcium carbonate putty powder is stirred easily and uniformly, caking is avoided, constructability is high, sprayed layers are flat, smooth, compact and firm, and powdering and cracking are avoided; meanwhile, the calcium carbonate putty powder has good water resistance and weather resistance, and the application range of the putty powder is effectively enlarged. The formula is simple, the materials can be obtained conveniently, cost is low, the effect is good, and the preparing method is simple, easy to operate and worthy of wide application and popularization.

Description

technical field [0001] The invention belongs to the technical field of putty production, and in particular relates to a calcium carbonate putty powder and a production process thereof. Background technique [0002] Putty powder is a kind of building decoration material, which is divided into two types: interior wall and exterior wall. The putty on the exterior wall should resist wind and sun, has high gelation, high strength, and a slightly low environmental index. The comprehensive index of interior wall putty is high, healthy and environmentally friendly. Usually, putty powder is composed of base material, filler, water and additives. In the construction process of architectural coatings, the quality of putty powder plays a decisive role in the quality of the coating film. It can be said that the above-mentioned problems such as the peeling off of the paint finish are closely related to the performance of the putty used for the primary treatment of the wall surface. Tradi...
