Description

Desert sand texture paint and preparation method thereof

Technical Field

The invention relates to desert sand texture paint and a preparation method thereof, and belongs to the technical field of paint.

Background

With the acceleration of the urbanization process of China, the demand of the coating is larger and larger, and the requirements on the quality of the coating and even on the artistic function of beautifying the environment of the coating are higher and higher. The texture paint is an emulsion paint which can make texture effect, and presents unique space visual angle by the infinite three-dimensional theory and multi-choice individual collocation, is rich and vivid, and is novel. The texture paint belongs to novel artistic coating, is derived from Greece peninsula, is widely used in foreign countries, and is more and more popular in domestic application in recent years. Currently, texture paint is gradually becoming one of the mainstream varieties of architectural coatings. However, the core raw material of the natural colored sand is a non-renewable resource, the resource is more tense along with the year-by-year increase of the using amount, the exploitation difficulty of the colored sand is continuously increased along with the popularization of the national environmental protection policy, and the natural colored sand resource prospect is more optimistic due to the fact that the environmental protection pressure is continuously increased. At present, a substitute product of natural colored sand is urgently needed in the market to meet the use requirements and the environmental protection requirements of people. The inventor and the team thereof continuously explore to finally lock the sight in the desert.

The national forestry agency published 6 and 17 th 2014, the inland history of China occupies 27.20 percent of the territorial area of China by 261.16 ten thousand square kilometers of naturally formed deserts and desertification regions, and is distributed in 528 counties of 18 provinces (autonomous regions and direct prefectures) such as inner Mongolia, Tibet, Shanxi, Gansu, Qinghai, Ningxia, Xinjiang and the like. If the existing desert sand can be utilized on the basis of controlling the desert enlargement, the unification of ecological benefit and economic benefit can be realized. The main body of the desert sand is silicon dioxide, if under the condition, auxiliary materials are selected in a targeted manner, are graded according to a certain proportion, are compounded with auxiliary agents such as a humectant, an acid-base regulator and the like, and are mixed through various processes to prepare the texture paint, which is a further practical place for the desert sand. In the prior art, desert sand particles are fine, the mud content is high, and the alkalinity is heavy, so the desert sand particles cannot be directly used for texture paint. Therefore, the desert sand is comprehensively utilized and becomes the sand required by the texture paint, so that the desert sand not only accords with the national policy of the political policy of sand control, but also becomes a building material capable of generating economic benefits for many years, and the current situation of the shortage of the texture paint sand resources can be greatly changed.

If hydroxyethyl cellulose ether, especially modified hydroxyethyl cellulose ether is added into the formula, the multifunctional assistant still has excellent water retention performance in an environment with higher alkalinity; on the premise of considering the cost, the dosage of the synthetic resin emulsion and the film-forming additive is properly increased so as to adapt to the characteristic of high oil absorption of the desert sand; the color paste adopts organic color paste and inorganic color paste to be reasonably matched for use, and the titanium dioxide adopts rutile type titanium dioxide, and the color difference problem caused by the dark color of the desert sand can be greatly solved under the combined action of the raw materials in a specific proportion. In addition, the large reserve of the desert sand can make up for the defect of large difficulty in mining due to the shortage of the reserve of the natural mineral white sand. In general, the desert sand texture paint adopts the desert sand to replace the natural mineral white sand to open a new way of the desert sand, so that the pollution and the damage of the natural mineral white sand to the environment are reduced, the utilization of the non-renewable resource natural mineral white sand is reduced, and the urgent requirement on environmental protection at present is further met. The inexhaustible desert sand reserves ensure the continuous supply of raw materials, reduce the dependence on natural mineral white sand and ensure the stability of production. The abundant color matching and different sand mold grading ensure that the texture effect of the texture paint is rich and variable and meets the aesthetic requirements of people.
