The invention discloses a transparent outdoor super hydrophobic self-cleaning coatings, comprising a solvent hydrophobic resin and two silazane treated roughness solid particles with six methyl, the added amount of two silazane treated roughness solid particles with six methyl hydrophobic resin for solvent with solid content of 1 ~ 5 times, the the solvent with hydrophobic resin from 2.84 ~ 5.68wt% seventeen fluorine decyl trimethoxysilane, 0.6 ~ 1.2wt% phenyltrimethoxysilane, methyl silicate is 0.45 ~ 0.9 wt%, the remaining part of the mixed solvent and hydrolysis condensation. The invention has strong hydrophobic and anti oil ability, and the contact area between the dirt and the coating surface is greatly reduced, and has the excellent automatic cleaning characteristic. The water rolls on the surface of the body as if on the lotus leaf without leaving traces of water. The invention is suitable for outdoor metal components, road guardrails, transmission towers, signal facilities along the railway and urban outdoor public facilities.
【技术实现步骤摘要】
一种透明户外超疏水自洁涂料
本专利技术涉及户外金属构件、公路护栏、输电铁塔、铁路沿线信号设施、城市户外公共设施等表面超疏水自洁涂料的合成技术,特别是一种用于玻璃、塑料、石材、陶瓷、金属、等基材表面的透明超疏水自洁涂料。
技术介绍
户外金属构件、公路护栏、输电铁塔、铁路沿线信号设施、城市户外公共设施外表面由于接触雨水、雾、泥浆、空气中水汽、粉尘、汽车尾气等,表面都会逐渐变脏。清洗特别工作量巨大、清洗施工操作困难。特别是脏污沉积,会对基材造成侵蚀,影响使用寿命。目前大部分户外金属构件、公路护栏、输电铁塔、铁路沿线信号设施、城市户外公共设施外表都是使用普通油漆类涂料,虽然有一定的保护功能,但没有自洁功能,需要定期清洗和维护,造成额外工作量。也有一些疏水型涂料,但是很多都是不透明的,水接触角一般也只有100度左右,疏水效果一般,有的疏水涂料还需要高温固化,限制了使用环境。
技术实现思路
:本专利技术针对现有技术中普通油漆和疏水型涂料存在的不足,提供一种具有透明、超疏水、自洁,且常温下也可固化成膜的超疏水自洁涂料。本专利技术要解决的技术问题所采取技术方案如下:所述透明户外超疏水 ...
