Embodiment 1

[0024] Embodiment 1: A kind of continuous glass fiber reinforced PVC prepreg is made by the following method:

[0025] (1) Take by weight 22 parts of PVC resin; 15 parts of plasticizer (8 parts of DOP, 7 parts of DBP); 3 parts of heat stabilizer (1 part of dibasic lead phosphite, 2 parts of tribasic lead phosphate ); 1.5 parts of lubricant (0.6 part of barium stearate, 0.3 part of lead stearate, 0.6 part of stearic acid); 1 part of light stabilizer uv944; 3 parts of grafting agent maleic anhydride grafted polyethylene.

[0026] (2) After accurately weighing various raw materials and additives, pour the PVC resin and plasticizer into the high-speed mixer, and then start the high-speed mixer at a low speed. After mixing at a low speed for 3 minutes, pour the heat stabilizer, lubricant, light stabilizer, and grafting agent into the high-speed mixer in sequence, and start the high-speed mixer at a low speed. After mixing for a period of time, when the temperature in the high-spee...

Embodiment 2

[0028] Embodiment 2: A kind of continuous basalt fiber reinforced PVC prepreg is made by the following method:

[0029] (1) Take by weight 25 parts of PVC resin; 18 parts of plasticizer (10 parts of DOP, 8 parts of DBP); 2 parts of heat stabilizer (0.6 part of dibasic lead phosphite, 1.4 parts of tribasic lead phosphate ); 1.5 parts of lubricant (0.6 part of barium stearate, 0.3 part of lead stearate, 0.6 part of stearic acid); 0.6 part of light stabilizer uv944; 2 parts of grafting agent maleic anhydride grafted polyethylene.

[0030] (2) After accurately weighing various raw materials and additives, pour the PVC resin and plasticizer into the high-speed mixer, and then start the high-speed mixer at a low speed. After mixing at a low speed for 3 minutes, pour the heat stabilizer, lubricant, light stabilizer, and grafting agent into the high-speed mixer in sequence, and start the high-speed mixer at a low speed. After mixing for a period of time, when the temperature in the h...

Embodiment 3

[0034]Embodiment 3: A kind of continuous carbon fiber reinforced PVC prepreg is made by the following method:

[0035] (1) Take by weight 30 parts of PVC resin; 20 parts of plasticizer (12 parts of DOP, 8 parts of DBP); 2 parts of heat stabilizer (0.6 parts of dibasic lead phosphite, 1.4 parts of tribasic lead phosphate ); 1.5 parts of lubricant (0.6 part of barium stearate, 0.3 part of lead stearate, 0.6 part of stearic acid); 0.6 part of light stabilizer uv944; 2 parts of grafting agent maleic anhydride grafted polyethylene.

Abstract

The invention provides a continuous fiber reinforced PVC pre-dip material and a preparation method thereof. The continuous fiber reinforced PVC pre-dip material comprises the following components: 50-60 parts of continuous fiber, 20-30 parts of thermoplastic resin, 15-20 parts of a plasticizer, 1-3 parts of a heat stabilizer, 0.5-1.5 parts of a lubricant, 0.5-1 part of a light stabilizer, and 1-3 parts of a grafting agent. The pre-dip material and the preparation method can solve the disadvantages of poor heat stability and poor liquidity of the original product, and the invention provides the moulding method with continuous production and stable performance, can keep the raw material characteristic with maximum degree, improves the processing moulding problem, can reach continuous production, and increases the comprehensive energy efficiency.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a continuous fiber reinforced PVC prepreg and a preparation method thereof. Background technique [0002] At present, with the development of composite materials, composite materials are widely used due to their specific strength, high specific stiffness and light density. One of the current development trends of composite materials is to replace traditional thermosetting epoxy composite materials with thermoplastic composite materials. . One of the reasons is that thermoplastic composite materials can be formed by simple heating, melting and cooling, and can be welded like metal. Therefore, the development of thermoplastic composite materials will bring about great changes in the future market. According to the "Thermoplastic Composite Materials Market" report released by MarketsandMarkets of the United States, by 2020, the market for thermoplastic composite materials will expa...
