Description
Technical field
The invention belongs to the field of building materials, and in particular to the detection method of a kind of water-whitening resistance U.S. porcelain cement and its performance.
Background technique
With the rapid development of building industry, the technology and material of building decoration area are also being continuously updated the replacement.Porcelain
Brick glue replaces cement to paste, and has not only saved material, reduces construction cost, and ensure that construction quality and project progress, also more
Add scientific environmental protection.Paving ceramic tile uses glue for tile, will become the trend of building decoration construction.The development of ceramic tile adhesive product is fast
Suddenly, all kinds of buildings be can solve substantially in process of construction, ceramic tile is laid with the various problems encountered.In order to preferably be construction industry
Service, in recent years, China has very big leap in glue for tile professional domain.
During being laid with ceramic tile, there are certain gaps for meeting between ceramic tile, and cement base joint sealing material is mostly used to carry out greatly
Jointing processing, but meeting blackening in its surface after 2-3 months of cement base joint sealing material even falls off, and cleaning difficulty is larger, not only not
Beauty, and be easy to shelter evil people and countenance evil practices, it spreads the disease, influences the usage experience of user.
The prior art generallys use U.S. porcelain cement to carry out jointing processing, but existing U.S. porcelain cement is cured in high humidity
In the case of, surface will appear apparent whiting, and water-whitening resistance can be insufficient, to affect the use of ceramic tile.Therefore, one
The good U.S. porcelain cement of kind water-whitening resistance is highly important for the construction of ceramic tile.
In addition, in the prior art for U.S. porcelain cement water-whitening resistance can detection none specific, system, effective side
Method, also there has been no one kind can quickly detect the detection method that U.S. porcelain cement water-whitening resistance can be fine or not, and construction personnel can not quickly sentence
The quality of disconnected U.S. porcelain cement water-whitening resistance energy often finds that the water-whitening resistance of U.S. porcelain cement can be poor, to carry out weight after construction
New construction, is unfavorable for judging the quality of construction effect, is also unfavorable for stablizing for construction and carries out.Therefore, one kind can be detected quickly
The detection method of U.S. porcelain cement water-whitening resistance energy quality is of great significance for the work progress and construction effect of U.S. porcelain cement.

Speed detects the water-whitening resistance of U.S. porcelain cement, and clearly judges the superiority and inferiority of its water-whitening resistance energy, makes guidance for arrangement and method for construction, has
It is carried out conducive to stablizing for construction, improves construction effect.
A kind of detection method of the performance of water-whitening resistance U.S. porcelain cement, which comprises the following steps: in code test
Under the conditions of sample is put into glue rifle, after the sample after squeeze out in glue mouth is mixed thoroughly, squeeze out sample is in a strip shape to glass
Change on brick, is struck off using scraper plate, test sample is made；The test sample is put into concrete curing box and conserves 18h, is taken out
6h is conserved under standard test conditions afterwards, checks whether the test sample surface has apparent whiting by visual observation；Root
Whiting grade is judged according to whiting situation.
Preferably, the standard laboratory conditions are temperature at 23 ± 2 DEG C, experiment condition of the relative humidity 50 ± 10%.
Preferably, the curing condition of the concrete curing box is 20 ± 1 DEG C of temperature, relative humidity >=90%.
The invention has the following advantages:
1, common amine curing agent is mainly used in existing U.S. porcelain cement, free amine content is higher, and hydrophobic effect is not
It is good, easily with CO in air2There is whiting in reaction, is unable to reach good water-whitening resistance.In order to make U.S. porcelain cement reach good
Waterproof effect, applicant needs that the curing agent that moisture absorption is low, free amine content is few is selected to be added in formula, therefore, application
This Shen is added by having selected polyethers ammonia, 1,6- hexane diamino, 1,3- hexamethylene dimethylamine as curing agent after largely testing in people
In formula please；Wherein, polyethers ammonia has good curability, and the moisture resistance of U.S. porcelain cement is remarkably improved after addition；It is existing
1,6- hexane diamino be mainly used for the resin of synthetic nylon 66 and 610, applicants have discovered that being used as curing agent is added to this
In invention, hydrophobic effect is good, can effectively improve the water-whitening resistance of product；Existing 1,3- hexamethylene dimethylamine mainly for the preparation of
Grade paint, the applicant pass through many experiments, it is found that after this product is added as curing agent in it, hydrophobic effect is good, resistance to
Water-white performance makes moderate progress；It therefore, can be effective by polyethers ammonia, 1,6- hexane diamino, 1,3- hexamethylene dimethylamine as curing agent
The water-whitening resistance energy for improving U.S. porcelain cement, avoids U.S. porcelain cement surface from the case where blackening occur, has good aesthetics and waterproofness；
2, applicant is by the way that, to each carry out rational proportion, each component is during mixing, asphalt mixtures modified by epoxy resin after many experiments
Rouge and curing agent, which pass through reaction, can form hard solidfied material U.S. porcelain cement, enable U.S. porcelain cement with good water-whitening resistance
Meanwhile the gap between ceramic tile and ceramic tile can be sufficient filling with, be not easy to fall off between gap, and moisture will not by gap to
It penetrates into ceramic tile, effectively increases the waterproof ability of ceramic tile, avoid that ceramic tile is mouldy, appearance of nigrescence phenomenon, to have good
Construction effect and user experience；
3, water-whitening resistance U.S. porcelain cement provided by the present application passes through the selection curing agent that moisture absorption is low, unhindered amina is low, and to amine
Suitably modified (epoxy reaction is added) is carried out, and each component is reasonably matched, to have good water-whitening resistance
Can, after carrying out jointing processing to the gap ceramic tile, solidification is not in whiting under high humidity environment, and it is specious,
Easy cleaning, will not blackening even fall off, and due to its good hydrophobic performance, it is not easy to shelter evil people and countenance evil practices, anti-pollution characteristic is good,
Construction is simple is convenient, is conducive to the progress of construction.
4, due to the prior art for U.S. porcelain cement water-whitening resistance can detection there has been no a kind of specific, system, effectively, quickly
Method, therefore applicant makes inspection provided by the present application after formulating a variety of detection schemes, implementing repeated detection experiment
Survey method；The detection method can quickly and efficiently detect the water-whitening resistance of U.S. porcelain cement, and testing result is concise, and should
Method is easy to operate, quick, without using a large amount of human and material resources, while effectively detecting U.S. porcelain cement water-whitening resistance energy,
Correct guidance is made for construction, improves construction effect, saves the construction time, is carried out conducive to stablizing for construction.
