Material and preparation method thereof.
Background technology
The enhancing PP materials typically used at present, in order to ensure the high intensity of material, can use common fiberglass reinforced, due to
Glass meeting streamwise orientation, causes the contraction of flow direction and the contraction perpendicular to flow direction to differ greatly, shrinks not
Balance causes warpage.
Fiberglass reinforced PP has good because of its good processing characteristics, tensile strength and resistance to elevated temperatures on household electrical appliance
Using such as used in air-conditioning wind wheel fan blade, wind wheel fan blade has higher want due to the requirement of air output to the buckling deformation of material
Ask, deflection is big, and product air output is different, while the unqualified phenomenon of dynamic balancing also occurs in flabellum, while in view of wind
Wheel flabellum is generally used for open air, and under hot and humid use environment, the phenomenon of aging, the mechanics of material also occurs in material
Degradation, mechanical performance for wind wheel flabellum and using having very big hidden danger.Processing and making additionally, due to PP resins
Electrostatic charge is easily accumulated during, can also cause material to adsorb dust, in order to reduce destruction of the dust to product, is improved simultaneously
The weather resistance of material strengthens weather-proof PP materials, it is necessary to which we develop antistatic low warp glass fiber.
The mechanical property of fiberglass reinforced PP resins is heavily dependent on the bond strength of PP resins and glass, due to tree
The water ratio limit of fat and glass is poor, and material compatibility is poor, it is impossible to give full play to the humidification of glass, the rigidity of material,
Toughness can be all greatly affected, it is necessary to improve the compatibility of PP and glass.
The addition of mica powder can influence the toughness of material, improve the warpage performance of material, it is ensured that toughness of material is needed to material
Material carries out toughness reinforcing, increases the materials'use life-span.
Because glass-fibre reinforced resin material has broad application prospects, therefore it is badly in need of developing a kind of antistatic low warpage
The weather-proof PP materials of fiberglass reinforced.
The content of the invention
