CN104804632A - Efficient external wall paint - Google Patents

Abstract

An efficient external wall paint comprises the following raw materials by weight: 6 to 14 parts of melamine, 2 to 7 parts of azodiisobutyronitrile, 5 to 10 parts of ceramic fiber, 3 to 8 parts of an acrylic emulsion, 1 to 4 parts of a dispersion wetting agent, 2 to 7 parts of sodium chloride, 5 to 11 parts of alkyl succinic imide, 6 to 9 parts of dioctyl phthalate, 9 to 15 parts of gamma-isocyanate propyl triethoxy silane, 2 to 5 parts of a preservative, 1 to 3 parts of a film-forming additive, 2 to 6 parts of acetone, 1 to 4 parts of a drier, 6 to 9 parts of aluminum oxide powder, and 5 to 14 parts of a water-based polyurethane emulsion. The efficient external wall paint has the benefits that the water resistance and soil resistance are excellent; the tenacity is relatively high; phenomena of cracking, peeling and the like are reduced.

Description

A kind of exterior coating efficiently

Technical field

The present invention relates to a kind of exterior coating efficiently, belong to paint field.

Background technology

Exterior coating, for brushing the outer wall face of building, exterior coating requires water repelling property, requires from washing property.Paint film wants hard and smooth, dirty once rushing.Simultaneously due to exterior coating under irradiation by sunlight throughout the year, as thermal insulation is bad, temperature within doors can be caused too high, have impact on the comfort level of people, and easily occur that coating easily ftractures, efflorescence, peel off, the phenomenon such as variable color.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of coating used for building exterior wall, has good water tolerance and resistance to soiling, and toughness is better simultaneously, not easily occurs phenomenons such as ftractureing, peel off.

For solving prior art problem, technical scheme provided by the invention is, a kind of exterior coating efficiently, and it is made up of the raw material of following parts by weight:

Trimeric cyanamide 6-14 part, Diisopropyl azodicarboxylate 2-7 part, ceramic fiber 5-10 part, ACRYLIC EMULSION 3-8 part, dispersion wetting agent 1-4 part, sodium-chlor 2-7 part, alkyl succinimide 5-11 part, adjacent benzene dicaprylate 6-9 part, γ-isocyanic ester propyl-triethoxysilicane 9-15 part, sanitas 2-5 part, film coalescence aid 1-3 part, acetone 2-6 part, siccative 1-4 part, titanium dioxide two aluminium powder 6-9 part, aqueous polyurethane emulsion 5-14 part.

The invention has the beneficial effects as follows: coating used for building exterior wall of the present invention, has good water tolerance and resistance to soiling, toughness is better simultaneously, not easily occurs phenomenons such as ftractureing, peel off.
