Problems solved by technology

However, this type of sizing agent is still based on epoxy resin, and various defects in the above-mentioned processing and application process are still unavoidable
[0005] The preparation of pure polysulfone resin-based carbon fiber sizing agent by traditional methods usually requires chemical grafting modification of polysulfone resin or dissolution with a large amount of organic solvents. Great impact, poor economy

Embodiment 1～8

[0033] Put the quantitative polyarylsulfone 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 40wt% of the total feeding amount, start the mechanical stirring, continue stirring at a certain speed, and continue to add the remaining A certain amount of water, stirred for a certain period of time to obtain a uniform white emulsion, discharged and transferred to the stirred tank B equipped with a high-speed emulsifier, added a certain amount of polyvinyl alcohol, opened the high-speed emulsifier, continued to stir at a fixed speed, and discharged A milky white suspension sizing was obtained.

[0034] The polyarylsulfone resin powder, sodium polyacrylate, and polyvinyl alcohol are from BASF Co., Ltd. The solid components of the suspension sizing agents prepared in Examples 1-8 are shown in Table 1, the composition and dosage of the sizing agents are shown in Table 2, and the...

Abstract

The invention discloses a polysulfone resin-based carbon fiber suspension sizing agent and a preparation method thereof. The polysulfone resin-based carbon fiber suspension sizing agent is composed ofpolysulfone resin powder, sodium polyacrylate, polyvinyl alcohol and deionized water, wherein the polysulfone resin powder accounts for 65-75wt% of the total mass of the solid components, the sodiumpolyacrylate accounts for 10-15wt% of the total mass of the solid components, and the polyvinyl alcohol accounts for 15-20wt% of the total mass of the solid components. The sizing agent prepared 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 polysulfone resin-based composite materials, and have high temperature resistance and strong interface bonding capacity.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber sizing agents, in particular to a polysulfone resin-based suspension type sizing agent and a preparation method thereof. Background technique [0002] Polysulfone resin is an excellent engineering plastic with excellent mechanical properties, good dimensional stability and outstanding creep resistance, low molding shrinkage and outstanding thermal stability. Therefore, polysulfone resin is an important thermoplastic heat-resistant engineering plastic, and it is also a promising matrix resin for composite materials. In recent years, carbon fiber reinforced polysulfone resin composites have attracted the attention of domestic and foreign engineers and technicians because of their unique physical and chemical properties. Among them, the process and interface performance of carbon fiber and polysulfone resin have attracted more attention. The two-phase interface of carbon fiber reinforced polysu...
