Number is easily rubbed off and is difficult identified, causes product rejection.
The present invention is mixed by twin-screw and extruded so that PBT mainly by adding adhesive aid in PBT resin
Preferable adhesive property is presented in plastics between 100 DEG C -200 DEG C.When ink carries out spraying printing, ink can be good at gluing
Knot is in product surface.
The present invention using powdered epoxy resin and polyvinyl alcohol as compound binding agent, in epoxy resin and polyvinyl alcohol point
Epoxy-functional and hydroxyl not containing polarized, both auxiliary agents can evenly spread to PBT resin and table in high temperature co-extrusion
Face.And the temperature of PBT resin product after injection is substantially all more than 150 DEG C, at this temperature using inkjet printing after, oil
Organic matter in ink can improve the combination between PBT and ink with epoxy-functional and hydroxyl reaction formation chemical bond and hydrogen bond
Power.When PBT products are touching this kind of material of gasoline, chemical bond therein is still more stable.Therefore, in the invention
The ink sprayed on PBT will not be cleaned by gasoline.

Compound.
Above-mentioned resistance to gasoline is cleaned in PBT material, and described coupling agent is aminopropyl triethoxysilane.
The preparation method of the above-mentioned low-temperature impact-resistant PBT material for exempting from spraying pearl effect, comprises the following steps：
By PBT resin, powdered epoxy resin, polyvinyl alcohol, silane coupler, toughener, antioxidant, PETS and dried pearl
Light powder is stirred, and mixing speed 2000r/min, mixing time is 3min.Mixed raw material is added in hopper, passed through
Double screw extruder carries out extruding pelletization, and extrusion temperature is 235 ~ 250 DEG C, and screw speed is 400 ~ 450r/min, is produced described
Resistance to gasoline cleans PBT material.
Compared with prior art, the present invention has advantages below and beneficial effect：
1st, the preparation method of resistance to gasoline scouring PBT material proposed by the present invention is simple, and process is few, and cost is relatively low.
2nd, the present invention can prepare resistance to gasoline and clean using powdered epoxy resin and polyvinyl alcohol as highly effective binder
PBT material.
