Description
Technical field
The present invention relates to a kind of epoxy resin cellar well lids and preparation method thereof using post-consumer glass fiber.
Background technique
Glass fibre is first is that being raw material through works such as high temperature melting, wire drawing, doff, woven fabrics using glass marble or post-consumer glass
Skill.Various product is eventually formed, the diameter of glass fiber single filament is equivalent to a head from several microns to twenties meters microns
The 1/20-1/5 of hair, every bundle fiber precursor is made of hundreds of even thousands of monofilament, usually as the increasing in multiple material
Strong material, electrically insulating material and heat-insulating material, circuit substrate etc. are widely used in national economy every field.
Epocel cloth is to be soaked with glass fabric using epoxy resin as ground, is formed through hot pressing.Epoxy resin mainly at
Part is phenolic resin；Phenolic resin be phenol and formaldehyde under catalysts conditions polycondensation, it is neutralized, washing and made of tree
Rouge, wherein being most important with phenol and formaldehyde resin.It is also the still critically important high score so far in the world earliest by artificial synthesized
Sub- material can be divided into two class of thermosetting property and thermoplasticity because selecting the difference of catalyst.Phenolic resin has good acid resistance
Energy, mechanical property, heat resistance are widely used in the industries such as anticorrosion engineering, adhesive, fire proofing, grinding wheel manufacture.
And the leftover pieces and dust that cellar well lid currently produced on the market generates in process of production are excessive, both produce dirt
Dye, and the health of worker is compromised, while intensity is lower, wear-resisting acid-fast alkali-proof is weaker, and service life is short, anti-flammability and insulation
Property is low, and comprehensive mechanical property is weaker.
A kind of glass-epoxy cellar well lid of earlier application and preparation method thereof, needs using excessive formaldehyde,
Harm can be generated to environment, so its production and using will be greatly limited.
