Description
Technical field
The present invention relates to technical field of composite materials, and in particular to a kind of PPS fiberglass reinforced of high paint adhesion is compound
Material and preparation method thereof.
Background technique
Polyphenylene sulfide (PPS) is a kind of thermoplastic special engineering plastic of excellent combination property, and the feature protruded is resistance to
High temperature, corrosion-resistant and superior thermoplastic.The chemical structure of PPS itself is quite stable, and good mechanical property.PPS is
Sulfur-containing aromatic polymers, for line style PPS at thermosetting plastics after 350 DEG C or more crosslinkings, branched chain type structure PPS is anti-flammability
Element --- sulphur, therefore, PPS have excellent flame resistance.Intensity is general, and rigidity is fine, but matter is crisp, is also easy to produce stress embrittlement；
Intolerant to organic solvents such as benzene, gasoline；Long-term use temperature keeps stablizing in 400 degree of air or nitrogen up to 160 degree.It is logical
It crosses addition glass fibre or other reinforcing materials is modified, impact strength can be made to greatly improve, heat resistance and other machinery
It can also increase, density increases to 1.6-1.9, and molding shrinkage is reduced to 0.15-0.25%.
PPS is in mechanical industry especially suitable for component preparation in the environment of high humidity, deep-etching.For shell, knot
Component, wearing piece and sealing material, specifically just like: pump case, pump impeller, valve, bearing, the support of bearing, piston ring and gear, pulley,
Fan, flow meter component, ring flange, Universal-head, counter, level etc..PPS can account for 30% for electronic apparatus industry, it is suitable
It is higher than 200 DEG C of high temperature electric elements together in environment temperature；It can manufacture that the point on generator and engine is rinsed, electricity rinses bracket, opens
Dynamic device coil, shielding case and blade etc.；On a television set, it can be used for high voltage shell and socket, binding post and terminal board etc.；

The components of device, gear-box, the support of bearing, lampshade, bumper, fan, exhaust system and reflective mirror and spot lamp holder.PPS can
Exhaust tube circulating valve and water pump vane, pneumatic signal demodulator etc. are made instead of metal；It can also be used for household electrical appliance: thermal chimney,
The protective coating and components of curler, hair dryer, hair iron, micro-wave oven, coffee pot, dryer, electric iron, electric cooker etc..
For the aesthetic of product, the product of part PPS fiber glass reinforcement need surface spray paint with
Achieve the effect that light.The crystallinity of PPS is high, surface polarity is low, surface tension is small, thus PPS glass fibre reinforced composite material with
The poor adhesive force of paint, the problems such as being easy to happen paint.Generally using the side such as corona and flame in plastic oil injection paint industry
Method promotes adhesive force to enhance the activity of material surface, but operating procedure and efficiency, controllability are all undesirable, effective method
It is that is, to be equivalent to one layer of adhesive force inorganic agent by first spraying one layer of priming paint, is sprayed between ground and paint, improves interlayer
Adhesive force solves Qi Wenti.But the technique of first primer spray topcoating again has been difficult to adapt to increasingly stringent environmental regulation,
It will cause the rising of cost.
Therefore, how modified on material, the paint adhesion for improving PPS glass fibre reinforced composite material is one and urgently solves
