Abstract
The invention relates to a composite material which is used to manufacture automobile bottom deflectors; the composite material consists of UP resin P171-903B, flexible resin P193-01, fiber glass, low profile additive H814-902, styrene, BYK996, 501 anti-oxidant, heavy calcium carbonate, PBTB, MgO, conductive carbon black powder, Al(OH)3 and zinc stearate. The density of the prepared automobile bottom deflector is 1.8, which meets the light-weighted trend of the prior automobile; the deflector plays the roles of buffering and protecting the passenger carriage; meanwhile, the strength-to-weight ratio (the ratio of ultimate tensile strength to density) is higher than that of metal; the corrosion resistance in adverse environment is excellent, the bottom deflector is located at the car bottom; the size is precise, the stability is stable and good strength is kept in a wide temperature range; the inflaming retarding and aging resistance are excellent.
Description
Technical field
The present invention relates to technical field of composite materials, particularly a kind of matrix material for making automobile bottom guide plate.
Background technology
Automobile bottom guide plate makes the smooth sealing of bottom of car structure, and air-flow can pass through the bottom fast, reduces because the raising force that turbulent flow causes has been equivalent to increase the earth-grasping force of tire, and then has improved the car load High-speed running stability.External medium-to-high grade automobile has installed baffle at bottom additional in the bottom basically at present, and material is mainly metal and fibre reinforced plastics.The density of metal material is higher; do not meet the trend of current automotive light weight technology, and the intensity of metal is high, the specific tenacity ratio of density (ultimate tensile strength with) is low; be unfavorable for the buffer protection to passenger compartment, the erosion resistance of the flow deflector of metal material in severe environment is lower.The flow deflector stability of plastic material is low, can not keep good intensity in the temperature range widely, and anti-dissolubility and ageing resistance are limited.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of matrix material that is used for making automobile bottom guide plate that overcomes existing material defective.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
Be used for to make the matrix material of automobile bottom guide plate, formed by the raw material of following weight part: UP resin P171-903B 47-50 part, flexible resin P193-01 4-65 part, glass fibre 26-28 part, low shrinkage additive H814-902 43-45 part, vinylbenzene 4-6 part, BYK996 0.8-1 part, 501 oxidation inhibitor 0.2-0.3 parts, water-ground limestone 70-110 part, TBPB 1.3-1.5 part, MgO 0.8-1.1 part, conductive carbon black powder 1.5-2.5 part, Al (OH)
380-100 part, Zinic stearas 4-6 part.
In the present invention, does the length of glass fibre generally exist?-? is mm preferably? mm.
Above-mentioned matrix material needs to carry out slaking after mixing, and becomes a kind of Preblend after the slaking.The curing temperature 32-34 of this material ℃, curing time 48-55Hr.
Matrix material for automobile bottom guide plate provided by the invention is cut into the size of regulation with starting material when the formed automobile baffle at bottom, drop in the 145-155 ℃ of mould, and matched moulds solidifies 3min, takes out.It is as follows that the automobile bottom guide plate of making and the flow deflector of metal and plastic material are compared its advantage.
One, compare with metal material:
1, density 1.8, and aluminium lighter in the metal is 2.7, meets the trend of current automotive light weight technology;
2, intensity slightly is lower than metal, but in car body component, distortion when needing high strength to resist collision except the passenger compartment frame part prevents from pushing outside the occupant, what other parts needed is to rely on distortion to absorb the energy of collision, and passenger compartment is played buffer protection; Simultaneously, the specific tenacity ratio of density (ultimate tensile strength with) will be higher than metal;
3, the good corrosion resistance nature in severe environment, baffle at bottom is positioned at bottom of car, is subject to easily the invasion and attack of various oily matters and water.
Two, compare with the baffle at bottom of plastic material:
1, size is accurate, good stability, and keeping good intensity in the temperature range widely;
2, fire-retardant and low the density of being fuming;
3, good solvent resistance under severe environment;
4, good ageing-resistant performance;
5, the cost of material is low by unit volume.
