preparation example Construction

[0053] In the present invention, the preparation method of the organic-inorganic compound exterior wall finish paint preferably comprises the following steps:

[0054] Inorganic composite acrylic polymer emulsion, alkyl-ZnO 2 The modified organosilicon material, nano silicon emulsion and fluorocarbon surfactant are mixed to obtain an organic-inorganic composite exterior wall finish paint.

[0055] In the present invention, the inorganic composite acrylic polymer emulsion, alkyl-ZnO 2 The type, source and amount of the modified organosilicon material, nano-silicon emulsion and fluorocarbon surfactant are the same as those of the inorganic composite acrylic polymer emulsion, alkyl-ZnO 2 The type, source and dosage of the modified silicone material, nano-silicon emulsion and fluorocarbon surfactant are the same, and will not be repeated here.

[0056] The above-mentioned method for preparing the finish paint is simple and easy to implement, and is easy to realize industrial pro...

Abstract

The invention provides organic and inorganic compound finish for outer walls. The finish comprises components in parts by weight as follows: 40-50 parts of an inorganic compound acrylic polymer emulsion, 10-15 parts of an alkyl-ZnO2 modified organic silicon material, 0-15 parts of a nano silicone emulsion and 0.1-1 part of a fluorocarbon surfactant. According to the finish, the inorganic compound acrylic polymer emulsion is used as a main film forming matter, the alkyl-ZnO2 modified organic silicon material and the fluorocarbon surfactant are compatible, so that the outer layer of a finish film has excellent hydrophilia, the lyophobic inner layer of the finish film can effectively prevent further intrusion of a pollution source, and the finish for the outer walls has higher pollution resistance; the finish has the self-cleaning effect. The finish is a water-based material, is lower in carbon, more environment-friendly and more energy-saving and has good air permeability and waterproofness and higher ageing resistance. Experimental results indicate that the stain resistance of the finish is 3%-5%; the stain resisting effect is still below 5% after the finish is aged for 1000 h.

Description

technical field [0001] The invention relates to the technical field of organic-inorganic composite polymer materials, in particular to an organic-inorganic composite exterior wall finish paint. Background technique [0002] Since the 1990s, architectural latex coatings have been rapidly developed and widely used in my country. Building exterior wall latex finish paint not only plays a role of decoration and protection for buildings, but also has the advantages of light weight, safety, simple construction, high work efficiency, short construction period, convenient maintenance and update, and low cost. It is currently the building exterior wall decoration The most widely used class of important building decoration materials. [0003] At present, 60% to 70% of the building exterior wall decoration in China uses exterior wall latex finish paint. However, with the acceleration of industrialization and urbanization and the rapid increase of various vehicles, the air pollution i...
