Problems solved by technology

Although the incineration method can recover part of the energy, the incineration process consumes a lot of energy, and there are still problems from an environmental point of view.
A new technology for recycling carbon fiber composites enables the plastic matrix in the composite to be removed through a special incinerator, and the remaining carbon fibers can be recycled for reuse. Although this method is a step towards sustainable development, it does not represent Fully recyclable, as the plastic matrix is ​​destroyed during the recycling process and cannot be recycled

preparation example Construction

[0026] The present invention also provides a method for preparing the epoxy resin composition for rapid prototyping of fiber-reinforced auto parts, characterized in that, comprising:

[0027] 1) Preheat bisphenol A type epoxy resin 127, then add triglycidyl p-aminophenol JD-939, trifunctional glycidyl ether diluent XY636 and stir under vacuum conditions to prepare component A;

[0028] 2) Stir degradable aliphatic amine curing agent ACV-1001, degradable aliphatic amine curing agent ACV-1007, degradable hydrazide amine curing agent ACP-6002, degradable aromatic amine curing agent ACP-2001 and accelerator phenol to prepare Get B component;

[0029] 3) Mixing component A and component B to obtain an epoxy resin composition for rapid prototyping of fiber-reinforced auto parts;

[0030] Among them, the weight ratio of component A to component B is 100:20-30; relative to 80-95 parts by weight of bisphenol A epoxy resin 127, the amount of JD-939 is less than 15 parts by weight, and ...

Embodiment 1

[0042] 1) Preheat the bisphenol A epoxy resin NPEL-127 to 50-55°C; add the preheated bisphenol A epoxy resin NPEL-127 to the reaction kettle; accurately weigh the additives, add Reaction kettle; add triglycidyl p-aminophenol JD-939 and trifunctional glycidyl ether diluent XY636 into the reaction kettle in sequence; in a vacuum environment, turn on the agitator and stir at a speed of 20-25rpm for 28-32min Stop; stop vacuuming, and return to normal pressure in the reactor to obtain component A.

[0043] 2) Add degradable aliphatic amine curing agent ACV-1001, degradable aliphatic amine curing agent ACV-1007, degradable hydrazide amine curing agent ACP-6002, degradable aromatic amine curing agent ACP-2001 and accelerator phenol into another In the reaction kettle; turn on the agitator, raise the temperature of the reaction kettle to 50-55°C, stir at a speed of 20-25rpm for 18-22min and then stop to obtain component B.

[0044] 3) Mix the A component and the B component prepared ...

Embodiment 2

[0047] The epoxy resin composition C2 was prepared according to the method of Example 1, the difference being that the weight ratio of component A to component B was 100:26; bisphenol A epoxy resin 127, triglycidyl group The weight ratio of aminophenol JD-939 to trifunctional glycidyl ether diluent XY636 is 90:0:10; degradable fatty amine curing agent ACV-1001, degradable fatty amine curing agent ACV-1007, degradable hydrazide amine curing The weight ratio of agent ACP-6002, degradable aromatic amine curing agent ACP-2001 and accelerator phenol is 40:60:0:0:10.

Abstract

The invention discloses an epoxy resin composition for rapid forming of fiber-reinforced automobile parts, a preparation method and a recycling method. The epoxy resin composition is prepared from a component A and a component B, wherein the component A is prepared from bisphenol A epoxy resin 127, triglycidyl p-aminophenol JD-939 and a trifunctional glycidyl ether diluent XY636; the component B is prepared from a degradable fatty amine curing agent ACV-1001, a degradable fatty amine curing agent ACV-1007, a degradable hydrazide amine curing agent ACP-6002, a degradable aromatic amine curing agent ACP-2001 and an accelerant of phenol. The epoxy resin composition disclosed by the invention can be rapidly cured at 110 to 120 DEG C, the viscosity is ultra low at 110 to 120 DEG C, reinforced fiber can be rapidly infiltrated, the epoxy resin composition is suitable for rapid molding technologies of HP-RTM (High Pressure-Resin Transfer Molding) and WCM (Wet Compression Molding), and the molding period of epoxy composite automobile parts can be shortened to 5 to 10 minutes.

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, a preparation method and a recycling method. 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 CO 2 The emission is 5g / km. Therefore, on the premise of ensuring the strength and safety performance of the car, reducing the curb weight of the car as much as possible can improve the fuel efficiency of the car, reduce fuel consumption, and reduce exhaust pollution. It is the best way to achieve energy saving and emi...
