Formula of carbon fiber modified material and preparation method thereof

Abstract

The invention discloses a formula of a carbon fiber modified material and a preparation method thereof. The formula of the carbon fiber modified material comprises 15-20 parts of carbon fibers, 5-8 parts of vinyltriethoxysilane, 6-8 parts of vinyltrimethoxysilane, 3-5 parts of Y-chloropropyltriethoxysilane and the balance purified water. After a certain proportion of coupling agent is added into the carbon fibers, the carbon fibers are large in volume density and heavy in weight and leaves a feeding cylinder by gravity, no 'bridging phenomenon' occurs, the content of the carbon fibers in modified plastic is uniform and stable, and accordingly the purpose of reinforcement is achieved. The modified carbon fibers are short, so that 'bridging in feeding' is effectively prevented, the feeding process is controllable, blanking is uniform, the reinforcement effect and product quality are ensured, the carbon fibers are effectively prevented from floating on a production site, and the risk is prevented that a motor and electric appliances are short-circuited by the carbon fibers.

Description

technical field [0001] The invention relates to a carbon fiber modified material, specifically a formula of a carbon fiber modified material and a production method thereof, belonging to the technical field of production and application of the carbon fiber modified material. Background technique [0002] Carbon fiber reinforced plastics, in the past, plastic and carbon fiber short fibers were loaded into a high-speed mixer according to a certain weight, and then mixed and transported to the lower barrel to complete extrusion granulation. In this method, due to the different density and shape of the two, the mixing of plastic and carbon fiber is uneven, and the proportion of carbon fiber in the produced particles is uncertain and different. Later, carbon fiber material was used to enter the extruder from the barrel of the side feeder, but because the carbon fiber was not modified with carbon fiber, the carbon fiber would be in the process of being transported from the side fe...

Problems solved by technology

In this method, due to the different density and shape of the two, the mixing of plastic and carbon fiber is uneven, and the proportion of carbon fiber in the produced particles is uncertain.

Later, carbon fiber material was used to enter the extruder from the barrel of the side feeder, but because the carbon fiber was not modified with carbon fiber, the carbon fiber would be in the process of being transported from the side feeder barrel to the extruder due to the small volume density. When feeding by gravity, the carbon fiber will have a "feeding bridging" phenomenon, so that the carbon fiber cannot be fed into the extruder. "Feeding bridging" means that the short carbon fiber is transported from the barrel to the extruder. It cannot be conveyed evenly and smoothly by gravity, but forms a space without carbon fiber material at the bottom of the barrel, and there is no phenomenon of carbon fiber entering the extruder
