Technical field
The present invention relates to glass fibre and repair the field, be specifically related to a kind of tackiness agent and preparation method thereof.
Background technology
Glass fibre (English former by name: glass fiber or fiberglass) is a kind of ceramic of excellent performance.It manufactures through high temperature melting, wire drawing, doff, the technique such as weave cotton cloth take glass sphere or discarded glass as raw material, the diameter of its monofilament is that several microns are to twenties meters microns, the 1/20-1/5 that is equivalent to a hairline, every bundle fiber precursor are comprised of hundreds of even thousands of monofilament.Glass fibre is typically used as the strongthener in the matrix material, electrically insulating material and heat-insulating material, the national economy every field such as circuit substrate.
The intensity height is the outstanding advantages of glass fibre, and high-intensity characteristic makes glass fibre obtain widespread use, and has developed into novel engineering materials and structured material.But glass is a kind of hard brittle material, so the flexibility of glass fibre, wear resistance are relatively poor, is prone to phenomenon of rupture in the processing process.For the glass fibre with fracture reconnects, usually use tackiness agent.The raw material of existing tackiness agent generally comprises by weight:
Because ethanol and 78 ℃ of azeotropic of water, so ethanol can exist with the form of solution all the time, and the massfraction of water generally will account for more than 4% in solution.The tackiness agent glue cohesiveness that forms like this is relatively poor.
Summary of the invention
The invention provides a kind of tackiness agent;
The present invention also provides a kind of preparation method of tackiness agent.
Can prepare the tackiness agent that does not contain ethanol by adhesive preparation method of the present invention.
In order to achieve the above object, technical scheme of the present invention is achieved in that
