目前普通外墙涂料存在粘结强度较低、不防水、施工工艺复杂、施工成本较高等不足,在陈旧的瓷砖表面进行翻新施工难以实现。因此,开发了一种水性底面合一涂料,该涂料在腻子、水泥砂浆以及瓷砖表面均能施工且具有防水功能。经测试,该涂料耐洗刷性测试12000次,漆膜未出现破损、露底以及起泡现象,表明该涂料漆膜具有优异的耐洗刷性;透水性测试为0.1mL,表明漆膜具有优异的致密性和一定防水能力;粘结强度测试表明该涂料在多种处理条件下的水泥基层和釉面瓷砖表面均具有极强的粘结强度和附着力。水性底面合一涂料可免底漆,降低施工成本,且具有一定的防水功能,是一种具有巨大应用前景的多功能水性外墙涂料。
At present,the common exterior wall coating has some disadvantages,such as low bond strength,no waterproof,complex construction technology and high construction cost.It is difficult to renovate the old ceramic tile surface by using the common exterior wall coating.Therefore,a kind of waterborne coating of primer topcoat in one was developed,which can be applied on the surface of putty,cement mortar and ceramic tile and had waterproof function.After testing,the coating was tested 12000 times of scrub resistance.And the film had not been damaged,exposed or blistered,which shown the coating film with excellent scrub resistance.The water permeability test of the film was 0.1mL,which shown that the film had excellent compactness and certain waterproof ability.The bond strength test shown that the coating had very strong performance of bond strength and adhesion on the cement base and glazed tile surface under various treatment conditions.The coating can avoid primer,reduced construction cost,and had certain waterproof function.It was a multifunctional waterborn exterior wall coating with great application prospect.
