Description
Technical field
The invention belongs to the building material technical field, be specifically related to a kind of repairing building cracks and prefabricated panels piece material.
Background technology
Along with implementing deeply of China's energy-saving and emission-reduction work, the use of external thermal insulation system is also more and more general.But, in the application process of reality, because fabric structure form, the reason of aspects such as weather condition, system material, construction technology, construction management, even equally also there are some quality problems in the most sophisticated heat-insulation system, especially the crack problem of the outer facade of heat-insulation system is comparatively outstanding, gently then influence attractive in appearance, heavy then seep water, come off, the forfeiture energy-saving effect shortens buildings work-ing life.How adopting remedial measures, the crack problem of resolution system has become Focal Point of Common Attention in the industry.
To the structural fissured processing that the following base layer structure of thermal insulation layer causes, being divided into the crack that need carry out the structural strengthening processing does not only need two kinds of crack consolidation process with not needing the structural strengthening processing.
Need carry out the crack that structural strengthening is handled, should carry out consolidation process to the requirement of reinforcing, after processing to be confirmed is qualified, thermal insulation layer be repaired intact with corresponding material according to relevant department.
Not needing structural strengthening to handle the crack that only needs the crack consolidation process often adopts the anchor grouting agent to repair.Existing anchor grouting agent, as epoxy mortar, construction structure glue, remain in glued membrane fragility, viscosity is big, hardness is high, snappiness difference or cohesive strength, tensile strength is low, the crisp volumetric shrinkage of film forming is bigger, though it is or flexible but aging fast, cracking and be full of cracks on interface and colloid are followed the string and weak point such as intensity.
Summary of the invention
Technical problem to be solved by this invention be combine with multiple substrate interface that firm spy is of a specified duration, weather-proof, ageing-resistant, the back seam of squeegeeing becomes several seam shortcomings, good snappiness and rebound resilience, the existing certain tensile strength of dual cracking resistance have certain unit elongation reasonably combined simultaneously, the prefabricated panel piece ftractures, matches with surface layer application distortion, consistency is good, is suitable for dynamic seam, waterproof, insulation, heat insulation, sound insulation.
In order to address the above problem
On the one hand, the invention discloses a kind of repairing building cracks and splicing prefabricated wallboard material, it is characterized in that, this repairing building cracks and splicing prefabricated wallboard material are made up of A component and B component, and A component and B ingredients weight parts ratio are 1: 1-10
Wherein, the A component comprises the following composition of weight part and is:
Vinylformic acid 2-4
Epoxy or end-NCO base performed polymer 1
The B component comprises the following composition of weight part:
Softening agent 35
Filler 52.5
Thixotropic agent 1.5
Deaerating agent 1
One of in an embodiment, in the composition that the basic performed polymer of described end-NCO is polyurethane elastomer, rubber powder or acrylate and Resins, epoxy.
In an embodiment, described softening agent is selected from phthalic acid fat, aliphatic diacid fat, phosphoric acid fat, phenylformic acid two alcohol esters.
In an embodiment, described filler is selected from CaCO
3, TiO
2, clay, talcum powder, carbon black, SiO
2, or PVC stick with paste, wherein be preferably lime carbonate etc.
In an embodiment, it is silicone based etc. that described deaerating agent is selected from
In an embodiment, described thixotropic agent is selected from solid powder (as gas-phase silica, hydrogenated castor oil, polymeric amide, wilkinite), modified urea, non-ionic fluids etc.
On the one hand, the invention discloses described repairing building cracks and the application under construction of splicing prefabricated wallboard material.
The using method of repairing building cracks of the present invention and splicing prefabricated wallboard material is as follows:
Method one:
1, the filleting construction can be adopted one by one in independent crack.
2, the basic level requirement surface is firm, does not have loose, the floating grey free of frost of nothing,
3, open v type groove along the crack, groove width and to look site specific deeply fixed.(generally wide: deeply more than or equal to 2: 1, minimum deeply must not be less than 10mm)
4, the squeegee preparation of clay, this product is a two-pack, is made up of A component and B component, earlier the A component is all added in the B component, stirs with electric mixer, and leaves standstill after 15 minutes and use.
5, clean out with wire brush and hairbrush along crack fluting place.Pick with the undercoat brush earlier and stir the clay of squeegeeing wetting " V " type groove, then with the direct pointing of the clay of the squeegeeing crack that stirs, during filleting with putty knife elder generation raking both sides, make the material of squeegeeing stick the groove both sides, fill up in the middle of the groove again, and floating surface, protruding phenomenon appears as the clay of squeegeeing of " V " type groove in solidification process, and compacting gets final product behind surface drying.
Method two:
During cracklin, along seam both sides evolution type groove, wide 50-150mm, dark 1-5mm criticizes and scrapes above-mentioned materials, is pressed into high-strength reinforcement grid cloth, makes it to form the anti-cracking waterproof compound coating, also can not slot.
Also can adopt aforesaid method one, two to be used in combination.
The advantage of repairing building cracks material of the present invention is as follows: excellent vigorous knotting strength, with basic unit good adhesive is arranged, and high tensile, good flexible does not ftracture after the joint filling, seals and follows the crack and change, and effectively controls and cover crackle.Repairing building cracks material of the present invention can be used for the filling in exterior finish independence crack filling and repairings such as concrete, whitewash mortar, heat-insulation system and self-heat conserving Vierendeel girder and infilled wall interface slit etc., and the splicing and the seam that are used for Light trabs are repaiied.
