[0014] Select by mass meter

[0015]

[0016] Follow the steps below:

[0017] ①Put the water and glutinous rice slurry into the reactor according to the formula and stir for 15-30 minutes;

[0018] ②Add expanded perlite, sepiolite powder, powdered silicate fiber, bentonite, lime calcium powder in sequence at a stirring speed of 900r / min~1100r / min, and stir for 20-40min;

[0019] ③The finished product contains the external mortar paint containing the glutinous rice syrup film-forming auxiliary agent and packaged from the reactor.

Abstract

The invention mainly relates to the field of coatings and in particular relates to a water-based coating for external walls. An externally-used sand pulp coating adopting glutinous rice emulsion comprises 40-60 parts of water, 30-40 parts of glutinous rice emulsion, 9-10 parts of expanded perlite, 3-5 parts of sepiolite powder, 3-5 parts of powdery silicate fibers, 3-5 parts of bentonite and 1-2 parts of ash calcium powder by mass. The externally-used sand pulp coating has the beneficial effects that as the used materials are nontoxic and harmless and are odourless, the sand pulp coating has the characteristics of environmental friendliness and zero VOC (volatile organic compounds); the glossiness and color uniformity of films can be effectively improved and the films have good handfeel properties; stress relaxation between base resins, caused by shrinkage of dried coats can be used for improving the adhesion of the coats to substrates; the colloidal particles are bonded more closely and then the mechanical strength of the films is improved, so that the films can resist rupture and can be completely stripped and the weather resistance is more greatly improved.

Description

Technical field [0001] The invention mainly relates to the field of coatings, especially water-based coatings for exterior walls. Background technique [0002] The exterior mortar coating is simple in construction and has a variety of colors. It is suitable to embellish various decorations on it. The decorative effect is simple and generous. It is the most widely used wall decoration material. Film-forming aids are one of the important components of mortar coatings. Film-forming aids not only affect the synthesis of resin, the preparation, construction and drying of mortar coatings, but also the film-forming efficiency and quality of the coating film. Although the film-forming aids have a great effect on the film formation of mortar coatings, the film-forming aids used in the prior art are basically organic solvents. These film-forming additives first contain volatile organic compounds (VOC) and toxic volatile gases. During or after construction, they will volatilize harmful car...
