Abstract
The invention relates to an auxiliary material of a carbon fiber product and specifically relates to a carbon fiber sizing agent. The carbon fiber sizing agent is prepared from the following raw materials in parts by weight: 40-50 parts of polyether polyol, 10-20 parts of trichloro ethylene, 25-30 parts of methyl diisocyanate and 10-15 parts of dichloromethane. According to the carbon fiber sizing agent provided by the invention, the adhesive is strong in toughness and high in adhesive strength.
Description
Technical field
The auxiliary material that the present invention relates to carbon fiber product, is specially carbon fiber sizing agent.
Background technology
At present conventional carbon fiber sizing agent be mainly take resinae as main, particularly take epoxy resin as main.This based carbon fiber sizing agent is used and exists bad adhesion, problem, particularly carbon fiber product easy to crack to use in automobile or space flight in the product of carbon fiber, and impulsive force is larger, affects product service life.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, a kind of carbon fiber sizing agent is provided, adhesion strength is high, and overall performance is stable.
The technical scheme that technical solution problem of the present invention is taked is:
Carbon fiber sizing agent, is prepared according to parts by weight by following raw material,
40 ~ 50 parts of polyether polyol, 10 ~ 20 parts of trichloro-ethylenes, 25 ~ 30 parts of methyl vulcabond, 10 ~ 15 parts of carrene.
Preparation method is as follows for this carbon fiber sizing agent:
(1) polyether polyol and trichloroethylene solvent are poured in reactor, stirred and be warming up to 60 ~ 80 ℃;
(2) mixed solution making is poured in condenser pipe, reduced temperature to room temperature, then pour into again in reactor and drip methyl vulcabond, react;
(3) add and be warming up to about 90 ~ 100 ℃ reaction 40min, cool to room temperature discharging, the i.e. carbon fiber sizing agent of system after carrene.
The present invention can make carbon fiber sizing agent through above-mentioned steps, and this binding agent toughness is strong, and adhesion strength is high.
