Problems solved by technology

The density of the metal material is high, which does not conform to the current trend of lightweight automobiles, and the strength of the metal is high, but the specific strength (ratio of ultimate tensile strength to density) is low, which is not conducive to the cushioning protection of the passenger compartment, and the diversion of the metal material Plates are less resistant to corrosion in harsh environments
The deflector made of plastic has low stability, cannot maintain good strength in a wide temperature range, and has limited solvent resistance and aging resistance

Embodiment 1

[0021] Take 48kg of UP resin P171-903B, 5kg of flexible resin P193-01, 26kg of glass fiber, low shrinkage additive H814-902 44kg, styrene 4kg, BYK996 0.8kg, 501 antioxidant 0.2kg, heavy calcium carbonate 70kg, TBPB 1.3 kg, MgO 0.8kg, conductive carbon black powder 1.5kg, Al(OH) 3 80kg, zinc stearate 4kg, etc. are mixed into flake materials, and cured at a curing temperature of 33°C for 50 hours. Cut the above-mentioned material into a specified size, put it into a mold at 145°C, close the mold for 3 minutes and take it out. The obtained deflector is more in line with automobile strength and specific strength requirements, and has good solvent resistance and aging resistance.

Embodiment 2

[0023] Take 49kg of UP resin P171-903B, 4kg of flexible resin P193-01, 28kg of glass fiber, low shrinkage additive H814-902 43kg, styrene 5kg, BYK996 0.9kg, 501 antioxidant 0.25kg, heavy calcium carbonate 90kg, TBPB 1.4 kg, MgO 1.1kg, conductive carbon black powder 2.5kg, Al(OH) 3 90kg, zinc stearate 5kg, etc. are mixed into flake materials and cured for 55Hr at a curing temperature of 34°C. Cut the above-mentioned material into a specified size, put it into a 150°C mold, close the mold and cure for 3 minutes, and take it out. The obtained baffle had the same characteristics as in Example 1.

Embodiment 3

[0025] Take 50kg of UP resin P171-903B, 6kg of flexible resin P193-01, 28kg of glass fiber, 45kg of low shrinkage additive H814-902, 6kg of styrene, 1kg of BYK996, 0.3kg of 501 antioxidant, 110kg of heavy calcium carbonate, 1.5kg of TBPB , MgO 1.0kg, conductive carbon black powder 2.0kg, Al(OH) 3 100kg, 6kg of zinc stearate, etc. are mixed into a sheet material, and cured for 55Hr at a curing temperature of 34°C. Cut the above-mentioned material into a specified size, put it into a 150°C mold, close the mold and cure for 3 minutes, and take it out. The obtained baffle had the same characteristics as in Example 1.

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 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 [0001] The invention relates to the technical field of composite materials, in particular to a composite material used for making a bottom deflector of an automobile. Background technique [0002] The bottom deflector of the car makes the bottom structure of the car smooth and closed, and the airflow can quickly pass through the bottom, reducing the ascending force caused by turbulence, which is equivalent to increasing the grip of the tires, thereby improving the high-speed driving stability of the vehicle. At present, foreign mid-to-high-end cars have basically installed bottom deflectors on the bottom, and the materials are mainly metal and fiber reinforced plastics. The density of metal materials is high, which is not in line with the current trend of lightweight cars, and the strength of metal is high, and the specific strength (ratio of ultimate tensile strength to density) is low, which is not conducive to the buffer protection of the passenger compartment ...
