Embodiment 1～8

[0035] Put the quantitative polypropylene resin powder and sodium polyacrylate into the stirring tank A in sequence, and gradually add deionized water dropwise. When the amount of water added reaches 30wt% of the total feeding amount, start the mechanical stirring, continue stirring at a certain speed, and continue to add the remaining amount After stirring for a certain period of time, a uniform white emulsion is obtained, and the material is discharged and transferred to the stirred tank B equipped with a high-speed emulsifier, a certain amount of fatty alcohol polyoxyethylene ether is added, the high-speed emulsifier is turned on, and the stirring is continued at a fixed speed. The milky white suspension sizing agent was obtained by discharging.

[0036] The polypropylene resin powder is from China Petrochemical Co., Ltd., and the sodium polyacrylate and fatty alcohol polyoxyethylene ether are from BASF Corporation. The solid components of the suspension sizing agents prepa...

Abstract

The invention discloses a polyolefin resin-based carbon fiber suspension sizing agent and a preparation method thereof. The polyolefin resin-based carbon fiber suspension sizing agent is composed of polyolefin resin powder, sodium polyacrylate, fatty alcohol-polyoxyethylene ether and deionized water, wherein the polyolefin resin powder accounts for 65-75wt% of the total mass of the solid components, the sodium polyacrylate accounts for 10-15wt% of the total mass of the solid components, and the fatty alcohol-polyoxyethylene ether accounts for 15-20wt% of the total mass of the solid components.The sizing agent provided by the invention is used for preparing carbon fibers, and the prepared sized carbon fibers are suitable for intermediates such as carbon fiber fabrics and prepregs for polyolefin resin matrix composite materials, and have good processability and interface bonding capacity.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber sizing agents, in particular to a polyolefin resin-based carbon fiber suspension type sizing agent and a preparation method thereof. Background technique [0002] Carbon fiber reinforced thermoplastic composite material is a kind of reinforced material that has developed rapidly in recent years. In its preparation process, carbon fiber is first cut into short fibers with a length of 5-20mm, and then mixed with thermoplastic resin, and further processed by extrusion injection molding and other processes. Composite profiles prepared as a continuous homogeneous system. Polyolefin resin has rich raw materials, low price, easy processing and molding, and excellent comprehensive performance. It is currently the most widely used thermoplastic resin. Carbon fiber-reinforced polyolefin resin-based composites have good economics, processability and recyclability, and are gradually being valued by the ...
