Abstract
The invention relates to a cross linker of insulating anti-crack mortar, comprising the components with mass fraction as follows: 76-82% of acrylic emulsion, 0.4-0.7% of dispersant, 0.2-0.5% of wetting agent, 1.5-2.4% of thickener, 0.2-0.4% of fungicide and the balance of deionized water. The cross linker of the invention can improve the flexibility and waterproofness of the cement mortar, enhance the alkaliproof breaking strength retention of fiberglass gridding cloth and prevent the cement mortar alkali from eroding the fiberglass gridding cloth by covering the fiberglass gridding cloth so as to improve the service life pf the gridding cloth and ensuring more compact connection between the gridding cloth and the anti-crack mortar; a flexible polymer film layer and a hardening cement body interpenetrate each other and form a stable and flexible protective layer by firm bonding, thus solving the defect of overlarge elastic modulus and linear expansibility between an insulating layer and the protective layer and finish of the anti-crack mortar, achieving flexible release of stress and effectively reducing the linear shrinkage of the system.
Description
Technical field
The present invention relates to a kind of industrial chemicals for building, particularly a kind of anticracking grout linking agent that in the building insulating layer construction process, is used to soak alkali resistant glass fibre open weave cloth.
Background technology
Along with global resources are faced with more and more severe situation, how building energy consumption is reduced and get off to become a problem that needs primary study, and External Thermal Insulation Technology for External can be made huge contribution for building energy conservation.Now, the External Walls Heating Insulation of China still is in a starting, the stage of growth, also has many problems; Mainly be because the matching capacity between the system material is bad, each synthem " pliable and tough deflection is inconsistent; stress relief imbalance successively ", finally cause the heat insulation system cracking phenomena very general, not only influence the attractive in appearance of building external decoration, can produce following problem especially: (1) basic unit normal deformation causes and produces crack or hollowing phenomenon in the system.(2) can not resist owing to temperature, humidity variation produce stress.(3), thereby destroy the insulation compound system because relatively poor, rainwater of hydrophobic nature and surface water infiltration see through protective layer.
Summary of the invention
Purpose of the present invention provides a kind of rigidity of improving cement that has at the shortcoming that exists in the present External Walls Heating Insulation, makes it to have certain snappiness, outstanding cement compatibility, water tolerance and alkali-proof linking agent; And after linking agent self the contact ultraviolet ray, again can the self-crosslinking film forming, form the fabulous transparent film of one deck unit elongation.
Technical scheme of the present invention is: a kind of cross linker of insulating anti-crack mortar is characterized in that: the moiety of described cross linker of insulating anti-crack mortar and shared massfraction are as described below:
ACRYLIC EMULSION 76-82%
Dispersion agent 0.4-0.7%
Wetting agent 0.2-0.5%
Thickening material 1.5-2.4%
Sterilant 0.2-0.4%
Deionized water 15-18%.
Preferably, described dispersion agent is sodium lauryl sulphate or triethyl hexyl phosphoric acid.
Preferably, described wetting agent is the yellow basic succinate of anionic dialkyl group.
Preferably, described thickening material is an ether of cellulose.
Beneficial effect of the present invention is: 1, the sand-cement slurry generation crosslinking reaction of partial cross-linked dose of infiltration and anticracking grout protective layer, improved the flexibility and the water-repellancy of sand-cement slurry greatly.2, after the linking agent self-crosslinking film forming, coat glass fiber reticular cloth, thereby cut off sand-cement slurry alkali has improved grid cloth to the etch of glass fiber reticular cloth work-ing life.3, after the linking agent self-crosslinking film forming, good percentage elongation has strengthened the alkaline-resisting ultimate strength retention rate of glass fiber reticular cloth, and the tension resistance to cleavage of alkali resistant glass fibre open weave cloth is brought into play fully.4, because of the infiltration and the anticracking grout crosslinking reaction of linking agent, form special bridged bond, thereby make be connected between grid cloth and the anticracking grout finer and close, flexible polymer film and hardening of cement body run through mutually and are bonded to a firm resilient protective layer securely, thereby solve Young's modulus and the excessive defective of linear expansivity between thermal insulation layer and anticracking grout protective layer, the facing, reach flexibility stress and discharge, effectively reduce the system linearity shrinking percentage.
