Description

A kind of fiberglass reinforced polyethyleneterephthalate/polycarbonate alloy
Technical field
The present invention relates to polymeric material field, be specifically related to a kind of fiberglass reinforced polyethyleneterephthalate/polycarbonate alloy.
Background technology
Plasticization of Automobile is the development trend of automotive light weight technology.Auto body sheet is one of parts that in automobile, weight is maximum, and the plastic of wagon sheet is significant to alleviating car load deadweight.The vehicle body plastic plate of exploitation is based on fiberglass reinforced polyethyleneterephthalate (PET) at present, and the parts applied include front and rear covers, car door, vehicle body perpendicular plate, deep bead, tire backplate or even whole vehicle body.
Glass fiber reinforcement PET material has excellent mechanical property, electrical insulation capability, resistance to chemical corrosion and ageing-resistant performance.Glass fiber reinforcement PET material is in injection moulding process, owing to glass fibre orientation in the flowing direction causes anisotropy and the PET induction crystallization around glass, make goods flow direction shrink less than with flowing vertical direction on contraction, it is serious that this ununiform shrinkage result in product warpage.
Glass fibre acts primarily as carrying effect in PET matrix, in order to can better bond with resin matrix, generally glass fibre is carried out surface treatment.Processing method mainly has coupling agent treatment and grafting to process two kinds.Part small-molecule substance all can be incorporated into material by both approaches, and these small-molecule substances can evaporate when product pyrolytic coating, forms pore or bubble at lacquer painting, has a strong impact on product quality.
Merlon (PC) good mechanical performance, heat-resist.In glass fiber reinforcement PET material, add Merlon (PC), it is possible to reduce the degree of crystallinity of PET, reduce the ununiform shrinkage caused because of crystallization.Glass microballoon has spherical high symmetrical structure, adds glass microballoon, it is possible to use the symmetrical shape of glass microballoon alleviates the anisotropy because glass fibre orientation causes in fiberglass reinforced PET material.And then the problem solving glass fiber reinforcement PET material warpage.
Lanthanum element electronegativity is extremely low, active greatly, adopt liquid-phase chemistry deposition technique can under suitable condition with glass fibre, the silicon dioxide on glass microballoon surface and aluminium oxide generation chemical reaction.Lanthanum element can also react with C, H and the O in PET material.Fiberglass reinforced PET material serves as a connection, can obviously improve the wellability between glass fibre, glass microballoon and PET matrix, make it better and resin-bonding, while ensureing mechanical property, introduce without small-molecule substance, the problem solving the volatilization of spraying process small molecular material.
Summary of the invention
The invention provides a kind of fiberglass reinforced polyethyleneterephthalate/polycarbonate alloy.
Technical scheme is made up of three below step:
Step one, is dissolved in dehydrated alcohol by formula proportion is configured to solution by the one in lanthanum chloride, lanthana and lanthanum hydroxide or its combination；Above solution and glass fibre are mixed in proportion, add in homemade high-pressure sealed reactor, temperature 110～125 DEG C, after stirring 30 minutes, it is cooled to room temperature discharging, filters, dry.
Step 2, is dissolved in dehydrated alcohol by formula proportion is configured to solution by the one in lanthanum chloride, lanthana and lanthanum hydroxide or its combination；Above solution and glass microballoon are mixed in proportion, add in homemade high-pressure sealed reactor, temperature 110～125 DEG C, after stirring 30 minutes, it is cooled to room temperature discharging, filters, dry.
Step 3, weighs each component by following mass percent: polyethylene terephthalate 45～60%, Merlon 5～10%, glass microballoon 3～8%, toughener 3～8%, nucleator 0.1～2%, antioxidant 0.2～0.7%, and surplus is glass fibre.
PET, PC, PTW, nucleator and antioxidant are added mix homogeneously in high-speed mixer by proportioning after drying, mixed material addition double screw extruder melt extrudes.Glass fibre, glass microballoon are added by side feeding by formula proportion.Expressing technique is 260～270 DEG C of a district, 260～270 DEG C of 2nd district, 260～270 DEG C of 3rd district, 260～270 DEG C of 4th district, 245～255 DEG C of 5th district, 245～255 DEG C of 6th district, 245～255 DEG C of 7th district, 245～255 DEG C of 8th district, 245～255 DEG C of 9th district, 245～255 DEG C of tenth district；Engine speed is 400～600rpm；Side feeding revolution is 5～10rpm；Main feeding feeding revolution is 20～30rpm.Fiberglass reinforced polyethyleneterephthalate/polycarbonate alloy is obtained after water cooled, air-cooled, pelletize.
The invention has the beneficial effects as follows: the addition of PC can reduce the degree of crystallinity of PET, reduce the ununiform shrinkage caused because of crystallization.The addition of glass microballoon can utilize the symmetrical shape of glass microballoon to alleviate the anisotropy because glass fibre orientation causes.And then the problem solving glass fiber reinforcement PET material warpage.Replace coupling modifier and graft modification with rare earth compound modified glass fibre peacekeeping glass microballoon, it is to avoid the introducing of small-molecule substance, solve the volatilization problems of spraying process small molecular material.
