Abstract
The invention provides a flame-retardant unsaturated polyester mould plastic and belongs to the technical field of thermosetting mould plastics. The flame-retardant unsaturated polyester mould plastic is prepared from the following raw materials in parts by weight: 20-24 parts of unsaturated polyester resin, 14-16 parts of low shrinkage additive, 0.25-0.45 part of initiator, 0.003-0.01 part of polymerization inhibitor, 0.06-0.15 part of metal oxide, 80-95 parts of filler, 4-5 parts of silicon carbide crystal whisker, 5-10 parts of fire retardant, 1.2-1.6 parts of compound releasing agent, 22-27 parts of reinforced fibers and 2-3 parts of nano acrylonitrile-butadiene rubber. The flame-retardant unsaturated polyester mould plastic has the advantages of good mechanical property, electric property and flame retardant property and can be applied to parts of cars, daily and household appliances and the like; and after a test, the bending strength is more than 90 MPa, the impact strength is more than 30 KJ/m<2>, the shrinking percentage is less than 0.15%, the resistance is 1*10<13> ohm, the electric strength is 12.0 MV/m, the dielectric dissipation factor is 0.015, the arc resistance is 180 S, the proof tracking index is 600 V and the vertical combustion is (UL-94-V-03 mm)V-0.
Description
Technical field
The invention belongs to the duroplastic moulding materials technical field, be specifically related to a kind of fire-retardant unsaturated polyester die plastic.
Background technology
Along with unsaturated polyester die plastic is widely used in daily household electrical appliance, thereby not only require the material electrical insulating property desirable, and require flame retardant properties excellent.Again, because unsaturated polyester resin itself is not fire-retardant, need to just can play fire retardation by the synergy of additive component, and whether the choose reasonable of additive can exert an influence to the quality of electrical insulating property and flame retardant resistance, for this reason, the applicant has done experiment repeatedly, has formed technical scheme described below.
Summary of the invention
Task of the present invention is to provide the fire-retardant unsaturated polyester die plastic of a kind of mechanical property, electrical insulation capability and flame retardant properties excellence.
Task of the present invention is finished like this, a kind of fire-retardant unsaturated polyester die plastic, and it is that raw material by following parts by weight proportioning consists of:
In a specific embodiment of the present invention, described unsaturated polyester resin is Bisphenol a unsaturated polyester resin.
In another specific embodiment of the present invention, described low shrinkage additive is that solid content is the polymethylmethacrylate type low shrinkage additive of 38-40%.
In another specific embodiment of the present invention, described initiator is di-t-butyl peroxide; Described stopper is 2.6 di-t-butyls-4-cresols.
In another specific embodiment of the present invention, described metal oxide is magnesium oxide; Described filler is aluminium hydroxide.
Also have in the specific embodiment of the present invention, described silicon carbide whisker is that length-to-diameter ratio is 250 ~ 300 fibrous carbon SiClx.
More of the present invention and in specific embodiment, described fire retardant is melamine phosphate or TDE.
In of the present invention and then specific embodiment, described compound releasing agent is that 40% Zinic stearas and mass percent are that 60% calcium stearate forms by mass percent.
Of the present invention again more and in specific embodiment, described fortifying fibre is the glass fibre of length 6mm.
In again of the present invention and then specific embodiment, described nanometer paracril is nanometer sulfuration rubber powder.
Fire-retardant unsaturated polyester die plastic provided by the invention has the strong point of good mechanical property, electrical property and flame retardant properties excellence, can be applicable to the products such as automobile, daily household electrical appliance, and through test, flexural strength is greater than 90MPa, and shock strength (non-notch) is greater than 30KJ/m
2, shrinking percentage is less than 0.15%, resistance 1 * 10
13Ω, electrical strength 12.0MV/m, dielectric dissipation factor 0.015, the 180S of anti-electric arc, anti creepage trace index 600V vertical combustion (UL-94-V-0 3mm) V-0.
