Description

A kind of anticracking additive and application method for heat-preserving dry-mixed mortar

Technical field

The present invention relates to thermal insulation mortar field, and in particular to a kind of for the anticracking additive of heat-preserving dry-mixed mortar and use Method.

Background technology

Exterior-wall heat insulation dry-mixed mortar series of products are to reform and promote in recent years energy saving building according to national materials for wall What spirit grew up, though and insulation material a multitude of names currently on the market, no matter in which kind of insulation material, be unable to do without viscous Mixture, water-loss reducer, anti-cracking agent etc..Typically it is aided with the market using 107 serial glue of polyvinyl alcohol or redispersable latex powder The polymeric articles such as starch ether make thickener, water-loss reducer, binding agent, but because being limited to and being protected by these chemical products essence performances Warm dry-mixed mortar filling-material structure determined, the problems such as the caking property that should possess in mortar, thickening property, water-retaining property, application property not It can meet, thus product quality is also not guaranteed, and cost is also higher.

Number of patent application provides a kind of multi-functional addition of heat-preserving dry-mixed mortar for 200710051372.7 patent of invention Agent, pressed by sodium carboxymethylcellulose, pva powder, Lauxite, polyethylene glycol oxide (PEO), bentonite, lignocellulosic Ratio, which is weighed, to be mixed, and is had and is uniformly dispersed, dissolve that fast, viscosity is strong, the good, stable performance that thickens Water-saving effect, and can be with it Any chemical colloid and filler are compatible, dosage is small, cost is low for it, and energy-saving and environmental protection, are widely used in outer (interior) insulation of exterior wall Plaster insulation material, polyphenyl of mortar, dry-mixed mortar, granular polystyrene rubber cement, styrofoam is plastered the fields such as brushing gypsum.Because this adds Add agent high comprehensive performance, be not required in the said goods in the case of adding other polymer adhesives and thickening water-loss reducer, i.e., The caking property of mortar, water-retaining property, workability, application property are can reach, and the multiple effects such as the cracking resistance of product can be strengthened, and product Cost can also reduce by 1/3rd or so.

But use the additive, it is impossible to the drying time after construction is reduced, in the cracking resistance of enhancing product, though with one Fixed effect of anti-cracking, but do not adapted to require high building to cracking resistance.

The content of the invention

The present invention provides a kind of anticracking additive and application method for heat-preserving dry-mixed mortar, above-mentioned existing to solve Additive can not reduce the drying time after construction and not adapt to require cracking resistance the technical problem of high building.

To solve the above problems, the technical solution adopted by the present invention is as follows：

A kind of anticracking additive for heat-preserving dry-mixed mortar, it is made up of the component of following parts by weight：

Carbon conjugated triene -9,11,13- acid glyceryl ester 5-10 the parts of epoxidation 18；

Lignocellulosic 2-3 parts；

HEMA 2-3 parts；

Dibutyl tin laurate 1-2 parts.

The production method of the anticracking additive is extremely simple, and the carbon conjugated triene -9,11 of epoxidation 18,13- acid three is sweet Grease, lignocellulosic, the powder of HEMA and dibutyl tin laurate are abundant according to the above ratio Mixing can be prepared by.

A kind of application method of anticracking additive for heat-preserving dry-mixed mortar, by the anticracking additive, thermal insulation mortar with And water is according to mass ratio 1-2:100：30-50 ratio is used after being mixed in lucifuge stirring device.

In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：

In the present invention, the carbon conjugated triene -9,11 of epoxidation 18,13- acid glyceryl ester can be solidified and be glued glutinous by illumination Property excellent, using this product, building can be made to be dried in 24 hours, substantially reduce drying time, the carbon of epoxidation 18 Conjugated triene -9,11, the splendid viscous stickiness of 13- acid glyceryl esters plays excellent adhesive effect to each component, so as to prevent out Split, adapt to require high building to cracking resistance completely；Whole only to add water using process, product produces without harmful waste, right Environment is extremely friendly；Preparation method is simple, and production cost is low, can produce and apply extensively.
