preparation example Construction

[0022] The present invention also provides the preparation method of the above-mentioned epoxy resin composition for the rapid prototyping of fiber-reinforced auto parts, comprising:

[0023] 1) Preheat bisphenol A epoxy resin 127, then add trifunctional glycidyl ether diluent XY636, cycloaliphatic epoxy resin TTA21 and stir under vacuum to prepare component A;

[0024] 2) Diethylenetriamine DETA, isophoronediamine IPDA, methylcyclohexanediamine HTDA, 1,3-cyclohexanedimethylamine 1,3-BAC and 2,4,6-tri(dimethyl Aminomethyl)phenol DMP-30 was stirred to obtain component B;

[0025] 3) Mixing component A and component B to obtain an epoxy resin composition for rapid prototyping of fiber-reinforced auto parts;

[0026] Among them, the weight ratio of component A to component B is 100:15-25; based on the total weight of component A, the amount of bisphenol A epoxy resin 127 is 80-95% by weight, trifunctional glycidol The amount of ether diluent XY636 is 0-10% by weight, the amount o...

Embodiment 1

[0034] 1) Preheat the bisphenol A epoxy resin NPEL-127 to 50-55°C; then add the preheated bisphenol A epoxy resin NPEL-127 and various additives into the reactor; then add the trifunctional Glycidyl ether diluent XY636 and cycloaliphatic epoxy resin TTA21 were added to the reaction kettle in sequence; then in a vacuum environment, the agitator was turned on and stirred at a speed of 20-25rpm for 28-32min and then stopped; finally, the vacuum was stopped and the Return to normal pressure in the reactor to obtain the A component;

[0035] 2) The curing agent diethylenetriamine DETA, isophoronediamine IPDA, methylcyclohexanediamine HTDA, m-cyclohexanedimethylamine 1, 3-BAC and accelerator three-(dimethylaminomethyl ) Phenol DMP-30 into another reaction kettle; then turn on the agitator, stir at a speed of 20-25rpm for 18-22min and then stop to obtain the B component (according to the nominal tank barrel, nitrogen protection when filling the barrel gas)

[0036] 3) Mix the A com...

Embodiment 2

[0039] Carry out epoxy resin composition C2 according to the method for embodiment 1, difference is, the weight ratio of bisphenol A type epoxy resin 127, trifunctional glycidyl ether diluent XY636 and alicyclic epoxy resin TTA21 is 90:5:5.

Abstract

The invention discloses a fiber-enhanced epoxy resin composition for quickly forming an automobile part and a preparation method thereof. The fiber-enhanced epoxy resin composition for quickly forming the automobile part comprises a component A and a component B. The component A comprises bisphenol A epoxy resin 127, a three-functional group glycidyl ether diluent XY636 and alicyclic epoxy resin TTA21; and the component B comprises diethylenetriamine DETA, isophorone diamine IPDA, methyl cyclohexanediamine HTDA, 1,3-bis(aminomethyl)-cyclohexan BAC and 2,4,6-tri(dimethylamino methyl) phenol DMP-30. The epoxy resin composition can be quickly cured and is suitable for a quick curing forming process of a fiber-enhanced composite material by means of a high pressure pouring process (HP-RTM) or a wet process molding process (WCM) and the like. The fiber-enhanced composite material prepared by the epoxy resin composition has excellent mechanical properties. The preparation method of the epoxy composition has the advantages of being simple in process and convenient to operate.

Description

technical field [0001] The invention relates to an epoxy resin material, in particular to an epoxy resin composition for rapid prototyping of fiber-reinforced auto parts and a preparation method thereof. Background technique [0002] In recent years, with the sharp increase in the number of automobiles, energy and environmental protection issues have become increasingly severe. How to reduce automobile fuel consumption and achieve automobile power, economy, environmental protection, and comfort has become a worldwide issue. Studies have shown that every 100kg weight loss of a car can reduce fuel consumption by 0.3-0.6L per 100 kilometers and reduce CO2 emissions by 5g / km. Improving the fuel efficiency of automobiles, reducing fuel consumption and reducing exhaust pollution is one of the effective means to achieve energy saving and emission reduction. In addition, both at home and abroad are vigorously promoting and developing new energy vehicles, especially electric vehicle...
