Abstract
The present invention relates to an inorganic filling polypropylene reinforced composite material for microwave ovens, which is characterized in that the present invention comprises the components of 40 to 92 wt% of polypropylene resin, 5 to 40 wt% of inorganic filling material, 0.1 to 2 wt% of antioxidant, 0.05 to 2.5 wt% of resin acceptor and 2.8 to 20 wt% of toughening agent. The present invention has the advantages of high rigidity and thermal deformation temperature, good toughness, size stability and thermal ageing performance, and low thermal expansion coefficient, contraction rate and cost, and the present invention can be used as the plastic parts of the microwave ovens, such as the door seals of the microwave ovens, the fan brackets of the microwave ovens, the wind scoopers of the microwave ovens, the pins of the microwave ovens, etc.
Description
The present invention relates to a kind of matrix material, particularly a kind of inorganic filler reinforced polypropylene composite material for microwave oven.
Acrylic resin is one of five big resins for universal use, and the kind of modified polypropene also has broad variety, and purposes is also very extensive.Microwave oven requires polypropylene composite material to have higher rigidity, toughness, good dimensional stability and thermal ageing, higher heat-drawn wire, lower thermal expansivity, lower shrinking percentage and lower cost preferably with the acrylic plastering part.
The object of the present invention is to provide a kind of firm, good toughness, higher heat-drawn wire, good dimensional stability and thermal ageing, lower thermal expansivity and the inorganic filler reinforced polypropylene composite material for microwave oven of shrinking percentage.
Purpose of the present invention can reach by following measure: the weight percent of component of the present invention is an acrylic resin 40～92%, mineral filler 5～40%, oxidation inhibitor 0.1～2%, coupling agent 0.05～2.5%, toughner 2.8～20%.
Purpose of the present invention can also reach by following measure: the weight percent of component is an acrylic resin 65%, mineral filler 25%, oxidation inhibitor 1%, coupling agent 1.2%, toughner 7.8%.Described mineral filler is talcum powder, lime carbonate, barium sulfate or their composition.Described oxidation inhibitor is hindered phenol, thioesters and phosphite antioxidant.Described coupling agent comprises silane coupling agent, titanic acid ester coupling agent, aluminic acid ester coupling agent, the compound coupling agent of aluminium titanium.Described toughner comprises SBS, SEDS, POE, EPDM, second third glue, HDPE, LDPE, LLDPE.Described acrylic resin is copolymerization and the homo-polypropylene of melting index between 0.8～40g/10min.
In system, dose rigidity, heat-drawn wire and dimensional stability that the part mineral filler can increase material, reduce shrinking percentage, thermal expansivity and the cost of material.
Oxidation inhibitor makes polypropylene in processing and use satisfactory stability be arranged, and avoids color and luster, performance to change, and especially in the life-time service process, provides good thermal-oxidative aging property.
Coupling agent carries out surface treatment to mineral filler, forms the chemical bond bridge between mineral filler and polypropylene, increases interface interaction power and consistency, improves the over-all properties of material.
The effect of toughner provides the normal temperature toughness and the low-temperature flexibility of material, improves the breach and the non-notch resistance to impact shock of material.
The present invention has following advantage compared to existing technology: have higher rigidity and heat-drawn wire, toughness preferably, good dimensional stability and thermal ageing, lower thermal expansivity, shrinking percentage and cost can be used as microwave oven plastic pastes such as door for microwave oven envelope, fan for microwave oven support, microwave oven wind scooper, microwave oven stove pin.
