Abstract
The powdered interface treating agent consists of 425# portland cement 500 weight portions, 20-50 mesh sand 400 weight portions, 70-140 mesh sand 100 weight portions, hydroxyethyl cellulose 2-3 weight portions, redispersible latex powder 10-20 weight portions, and calcium formate 2-3 weight portions. It is suitable for plastering wall, and has high adhesion strength, high early strength, short construction period and other advantages.
Description
Technical field
The application relates to building wall and handles material.
Background technology
Along with eliminating of solid clay brick, various novel wall materials are widely used, as gas concrete brick, flyash brick, air-entrained concrete building block, lightweight GRC partition plate etc.Novel wall material more and more is subjected to people's favor owing to light weight, intensity height, do not destroy environment, advantages such as protection land resources etc.But be to use novel wall material also to exist the technical problem that some do not have solution.Because these novel wall material Surface Physical character have been compared very big difference with traditional clay brick, it is big to be mainly the surface void rate, at the bottom of water-intake rate height, light porous, the cohesive strength, therefore ordinary mortar is not suitable for building by laying bricks or stones and wiping one's face of above-mentioned type material, tend to cause tack coat cracking, hollowing, come off, quality problems such as seepage, these problems then can use the dried powder boundary agent effectively to solve.
Summary of the invention.
The application's purpose provides a kind of dried powder boundary agent, comes off, rises drum, rimose technical problem to overcome easily after traditional metope is handled the construction of material mortar.
For achieving the above object, dried powder boundary additive of the present invention is made up of the raw material of following weight part:
500 parts of 425# ordinary Portland cements, husky 400 parts of 20-50 purpose grating, husky 100 parts of 70-140 purpose grating, water-holding agent 2-3 part, tackiness agent 10-20 part, hardening accelerator 2-3 part.
Described water-holding agent is Natvosol (HEC)
Described tackiness agent is a redispersable latex powder, and this redispersable latex powder is a vinyl acetate-ethylene copolymer.
Described hardening accelerator is calcium formiate.
Above-mentioned water-holding agent, tackiness agent, hardening accelerator all are commercially available prod.
Its concrete production technique is: 1, carry out accurate weighing according to basic proportioning, 2, successively cement, tackiness agent, water-holding agent, hardening accelerator are dropped into mixing machine and carry out thorough mixing; 3, add the husky mixing of grain composition 15 minutes; Pack then and be dried powder boundary additive.
Constructional method one:
1, earlier basic unit is handled, remove surperficial floating ash, greasy dirt etc.Must the moistening metope of water before the construction.
2, about 1: 4 of water cement ratio (weight) stirs into required paste, and leaving standstill thoroughly stirs after 5 minutes again can use.The paste that mixes up should be finished using in 4-6 hour.
3, construction: evenly spread upon on basic unit's face with the mud plate, the about 2-3mm of thickness (being not less than 2mm) behind the 10-15 minute anhydrous light of rear interface, can smear cement mortar screeding., must divide and plaster several times greater than 1 centimeter as levelling thickness.
Constructional method two:
Select the high pressure spray nozzle of diameter 5mm, the spray pump of air pressure 7-8 kilogram, ratio of water to material is about 1: 3.5 and mixes pulpous state, and nozzle is sprayed into even trichobothrium shape apart from the about 0.5mm of metope; Every square metre of about 2-2.5 kilogram of consumption; Spray and to carry out metope in back 24 hours and scrape rough levelling.
Application notice of the present invention:
1, construction temperature should please don't be constructed when rainy more than 5 ℃;
2, guard against damp, waterproof, 6 months storage times.
Its positively effect is:
Dried powder boundary additive of the present invention improves cohesive strength by the tackiness agent that adds significant quantity, not hollowing, do not ftracture, plasticity-is big, is applicable to wiping one's face of various wallings, improves mutual cohesive force greatly.By water-holding agent that adds significant quantity and the water-retentivity that hardening accelerator has increased it, it is too fast and influence intensity to be unlikely to dehydration, has improved early strength, has shortened construction period.Overcome traditional ordinary mortar tack coat cracking, hollowing, come off, quality problems such as seepage.
After testing, every performance of the present invention such as table 1
Table 1
As can be seen from the table, every performance index of the present invention are far superior to national standard.
Embodiment
Be that example further specifies enforcement of the present invention below with the specific embodiment.
Accurately take by weighing 425# ordinary Portland cement 500kg, the dried husky 400kg of 20-50 purpose grating, 70-140 purpose grating dried husky 100kg, Natvosol 3kg, redispersable latex powder 10kg, calcium formiate 2kg.Start mixing machine then, earlier cement dropped into mixing machine, successively water-holding agent, tackiness agent, hardening accelerator are dropped into mixing machine mixing 2-3 minute again, the more husky mixing machine that drops into of grating was carried out thorough mixing 15 minutes, begin packing, dried powder boundary additive.
Above-mentioned Natvosol, redispersable latex powder, calcium formiate all are commercially available prod.
