Description
Technical field
The present invention relates generally to Material Field, particularly relates to a kind of permanent fire retardant PBT material.
Background technology
Polybutylene terephthalate, weathering resistance, water-intake rate are low, are only 0.1%, still keep various physical property (comprising electrical property), electrical insulating property, but volume resistance, dielectric loss are large in wet environment.Heat-proof water, bases, acids, oils but be subject to halon and corrode, hydrolytic resistance is poor, can crystallization rapidly under low temperature, good forming ability.Shortcoming is that notched Izod impact strength is low, and molding shrinkage is large.Therefore major part adopts glass fiber reinforcement or inorganic fill modification, its tensile strength, flexural strength can be enhanced about more than once, and heat-drawn wire also significantly improves.Can long term operation at 140 DEG C, after fiberglass reinforced, goods vertical, horizontal shrinking percentage is inconsistent, easily makes goods generation warpage.
PBT crystallization velocity is fast, and optimum working method is injection moulding, additive method is extruded in addition, blowing, coating and various secondary processing shaping, need predrying before shaping, moisture content will be down to 0.02%.
PBT (enhancing, modified PBT) is mainly used in automobile, electronic apparatus, industrial machinery and polymer alloy, blended industry.As the deflector coil as televisor in the divider in automobile, body part, ignitor coil skeleton, insulating cover, exhaust system component, motor cycle ignitor, electronic apparatus industry, picture tube and potentiometer support, sound accompaniment output transformer skeleton, adapter skeleton, switch connector, electric fan, refrigerator, motor for washer end cap, axle sleeve.
Also have Transport Machinery part, sewing machine and textile machinery part, casing for clock and watch, lens barrel, electric iron cover, mercury lampshade, roaster parts, power tool part, bell housing in addition.
