Abstract
The invention aims to provide a preparation method of a high-weather-resistance high-elasticity fluorine-silicon-modified acrylic emulsion for building thermal-insulation paints. The fluorine-organosilicon modification is implemented by polymerizing unsaturated-bond-containing organosilicon monomers with other unsaturated-bond-containing acrylate monomers, so that the high temperature resistance, weather resistance, chemical resistance, hydrophobicity, low surface energy and low fouling tendency of the organosilicon are combined with the high color retention, flexibility and adhesiveness of the acrylic resin, thereby preparing the high-elasticity high-weather-resistance high-water-resistance anti-fouling environment-friendly building emulsion and paint.
Description
Technical field
The invention belongs to water-fast, weather-proof, high resiliency thermal insulation coatings for building, a kind of for building thermal-insulating coating
Preparation method by high-weatherability high resiliency fluoro-fluorine-silicon modified acrylic emulsion.
Background introduction
Along with society and the high speed development of science and technology, environment and the energy become two asking greatly of whole world growing interest
Topic, and have higher requirement for environmental protection and energy saving.The demand of world energy sources with annual 2% speed increment,
And building energy consumption accounts for about the 30% of whole energy consumption.In AND ENERGY RESOURCES CONSUMPTION IN CHINA, building energy consumption constitutes about the whole nation
The 35% of energy resource consumption, it is reported, New Dwelling regulation, from 2008, will be taked heat-insulation and heat-preservation to arrange by China
Execute.
Building energy consumption has accounted for about the 33% of whole nation total energy consumption for developed country in the world, the most
In the case of drilling the strongest worldwide energy crisis, the hugest proportion, cause developed countries already
Attention.China as developing country, the total amount of its building energy consumption also with GDP rapid growth and by
Year rises, existing the most also already close to international level of developed countries, if not starting to focus on building energy conservation now,
To directly aggravate energy crisis, therefore, building energy conservation has become a great society sustainable development in China and the world
The theme of exhibition.The center of building energy conservation is on the premise of not affecting people's degree of being comfortable on, and reduces building consumption
Can, improve the efficiency of energy utilization in building.
For adapting to the needs that building thermal environments is improved, the building energy consumption of China will trend in geometric growth. as
Fruit is a large amount of builds high energy consumption building, then brings immense pressure not only can to China's energy supply, and can make
Becoming serious environmental pollution, this energy-saving low-carbon strategy current with China runs in the opposite direction.At building energy conservation
Become today of world trends, actively push forward building energy conservation, contribute to reasonable energy utilization, improve environment,
There is abnormal important economic implications and social meaning.
And along with industrial development and the raising of people's living standard, people to the greenization of coating products,
High performance, pollution-freeization and energy-saving require stronger, and traditional emulsion coatings has been difficult to full
The demand that foot people are growing.Organic fluoride-fluorine-silicon modified acrylic coating is that development in recent years rapidly and has wide
The new coating of wealthy market application foreground.It had both had organosilicon fire-resistant, ultra-violet resistance, resistance to oxidation fall
Xie Xing, surface can low, good permeability, have again acrylic resin pliability, protect light, colour retention,
High tack, is the coating variety of a class excellent combination property, aqueous Organic fluoride-silica acrylic acid coating environment friend
Good, be widely used as building coating, leather finishing agent and adhesive etc., can be especially useful for important building or
The exterior coating of person's high level high-rise building, from the nineties in 20th century, becomes people always and competitively opens
The focus product sent out, produce.Therefore, it is necessary to traditional acrylic emulsion is improved, to adapt to coating
Industrial expansion requirement.Organosilicon, Organic fluoride modified acrylic acid emulsion are the weights obtaining high-performance coating
Want approach.
Summary of the invention
It is an object of the invention to provide a kind of for the building thermal-insulating coating fluoro-Si modification of high-weatherability high resiliency
The preparation method of acrylic emulsion.Organic fluoride-Si modification that this problem uses is by having containing unsaturated bond
Machine silicon monomer contains each acrylate monomer of unsaturated bond and is polymerized with other, so that organosilicon fire-resistant,
