Description
Technical field
The present invention relates to a kind of two-component antibacterial anti-fouling epoxy joint trimming agents and preparation method thereof.
Background technique
Ceramic tile is a kind of finishing material largely used, and usual ceramic tile needs to be filled between ceramic tile with white cement after being laid with
Gap, although can achieve beautiful, antifouling and other effects, its rough surface is intensely dark, and is also easy to mildew and blacks,
It is difficult to clean.In recent years, occur a kind of novel pointing in the market --- joint trimming agent, in addition to joint filling effect with
Outside, the advantages that being also equipped with mould proof waterproof, easy to clean, not blackening, high glossiness, is becoming increasingly popular.
Currently, joint trimming agent on the market mainly includes two kinds of one-component joint trimming agent and two-component oiliness joint trimming agent.One-component
The generally existing shrinking percentage of joint trimming agent is big, the disadvantages of being easy to fall off.Two-component oiliness joint trimming agent have shrinking percentage is low, caking property is good,
The advantages that intensity is high, brightness is high is expected to gradually replace one-component joint trimming agent, becomes the market mainstream.However, existing two-component oil
Property joint trimming agent there is also following shortcoming and defect: 1) contain volatile organic matter (VOC) in two-component oiliness joint trimming agent, it is not only dirty
Environment is contaminated, but also human health can be damaged；2) T-me line paper is needed before constructing, avoids the contaminated difficult cleaning of ceramic tile, work of constructing
Sequence is cumbersome；3) commercially available two-component oiliness joint trimming agent can not keep beautiful for a long time, and germ easy to breed in a humidity environment,
Easily mildew blacks, it is difficult to clean, influence overall beautiful effect.
Therefore, need to develop that a kind of intensity is high, shrinking percentage is low, caking property is strong, brightness is high, is not easy mildew blacks, soil resistance
Good, joint trimming agent easy to clean.
