Description

A kind of exterior wall putty

[technical field]

The present invention relates to paint field, particularly be exterior wall putty, be used for levelling, joint filling, the repairing on industry and covil construction surface, improve work-ing life, wear resistance and the sticking power of finish paint.

[background technology]

Building coating occupies very important position in coatings industry, obtained development rapidly in recent years, and its kind and output are on the increase.Along with people to the deepening continuously of the understanding of building coating advantage, the demand of exterior coating will increase severely.But disadvantages such as foaming, decortication often appear in the building coating of China at present, have had a strong impact on protection and the decoration functions of coating to buildings.Cause the destructive major cause of filming to have two: the one, the quality problems of coating; The 2nd, substrate treatment is improper.Practice shows that the application failure more than 70% is improper relevant with substrate treatment.

Putty has obtained using widely as a kind of material of application surface preparation for the treatment of; it not only can be smooth, repair building surface; and superior in quality putty also can increase coating greatly to the protection of buildings and ornamental; prolong the work-ing life of coating; be the indispensable auxiliary products of high-performance building coating, especially exterior coating.

At present, some units in charge of construction adopt 107 glue+cement, lime, sand and dry powder etc. to drape over one's shoulders Puttying, because 107 glue are polyvinyl alcohol oxymethylene polymerization composition glue liquids, poor performance, product specification is low, and the formaldehyde that contains harmful ingredients, and country has prohibited use, but its low price still has certain market.Domestic construction is coated with the charge ash and scrapes when greasy in recent years, have to select high-grade polymer emulsion such as acrylic latex, butadiene-styrene latex for use, and neoprene latex, polyvinyl acetate etc., but owing to be bicomponent system, construction inconvenience, and cost is also high.

[summary of the invention]

The purpose of this invention is to provide a kind of single component high-strength water-resistance environmental protection exterior wall putty, this putty intensity height, water-tolerant, do not contain poisonous deleterious organic solvent, can be used for building surface and fill and lead up and repair, make object plane smooth, can save the finish paint consumption, easy construction, cost is low, can also improve the performance and the work-ing life of lacquer painting.

A kind of single component high-strength water-resistance environmental protection exterior wall putty, composed as follows by weight:
