Description
Technical field
The invention belongs to glass fiber compound material preparing technical field, there is provided a kind of high life glass fibre is answered
Plywood material and preparation method thereof.
Background technology
Glass fibre is a kind of excellent functional material and structural material, turns into and substitutes traditional materials such as steel, timber, cement
The important composite strengthening new material of material.With developing rapidly for market economy, glass fibre turns into building, traffic, electronics, electricity
The essential raw material of the industries such as gas, chemical industry, metallurgy, environmental protection, national defence.Due to being used widely in multiple fields,
Therefore, glass fibre is increasingly subject to the attention of people.Global glass productive consumption big country is mainly the hair such as the U.S., Europe, Japan
Up to country, glass consumption figure is higher per capita for it.
The fast development of Chinese glass fiber industry in recent years, pulling of the power from two market of home and overseas.State
The expansion in border market, the factor that existing aggregate demand increases, also have from international business early stage because of profit margin it is relatively low exit industry after,
The development space left to domestic enterprise in international market；And the growth of domestic market, then it is from the fast of downstream consumption industry
Speed development.Chinese glass fibre have passed through the development of more than 50 years, with considerable scale.China's glass fibre yield reaches within 2007
To 1,650,000 tons, to about 592.7 ten thousand tons of China's glass fiber industry yield in 2015 so that China turns into world's glass production the
One big country.China's glass fibre of the first half of the year in 2015 and product manufacturing scale above number of the enterprise 752, at present in the whole world
In the range of glass-fiber industry be still to maintain the Chaoyang industry of growth vigor.
Glass fibre has high intensity, flatness contracting, corrosion-resistant, electric insulation, nonflammable etc. excellent as a kind of reinforcing material
It is different in nature can, but also having the shortcomings that property is crisp simultaneously, not wear-resisting, poor processability, it is therefore necessary to is directed to glass fiber treating compound
Property processing, one layer of film forming matter of coating can be pacified in table i after processing, its processing characteristics substantially improve, and can produce relatively strong bond work
With.There is heat-proof quality with the sheet material of glass fiber matrix, be a kind of excellent heat-barrier material.Find in use, common
