Description
Technical Field
The application relates to the technical field of cable protection pipes, in particular to a glass fiber reinforced plastic material and a preparation method and application thereof.
Background
The glass fiber reinforced composite material is commonly called as glass fiber reinforced plastic, and has the advantages of high strength, high modulus, wear resistance, corrosion resistance, good insulating property, easy processing and forming and the like, so that the glass fiber reinforced composite material is widely applied to a plurality of fields. In the field of power cable protection pipes, compared with cable protection pipes made of common steel pipes, modified polypropylene (MPP), chlorinated polyvinyl chloride (CPVC) and the like, cable protection pipes made of glass fiber reinforced plastics have incomparable advantages.
At present, glass fiber is usually treated and modified by adopting a silane coupling agent, but the silane coupling agent is easy to self-condense into siloxane oligomer, the effective utilization rate is low, and an effective bonding part is very easy to hydrolyze. Therefore, in order to meet the application requirements, the interfacial adhesion between the glass fiber and the matrix in the glass fiber reinforced plastic still needs to be improved.
Disclosure of Invention
The application mainly aims to provide a glass fiber reinforced plastic material, a preparation method and application thereof, and aims to solve the technical problem that the interface bonding performance between glass fibers and a substrate in the conventional glass fiber reinforced plastic is insufficient.
In order to solve the above technical problem, an embodiment of the present application provides: the glass fiber reinforced plastic material is obtained by sequentially carrying out plasma surface treatment and glue solution dipping on glass fiber cloth;
the atmosphere gas for the plasma surface treatment includes at least one of oxygen plasma, nitrogen plasma, and air plasma.
As some optional embodiments of the present application, the glue solution comprises the following components in parts by weight: 90-120 parts of unsaturated polyester resin, 20-40 parts of boron nitride, 0.02-0.05 part of carbon nano tube, 0.01-1 part of silane coupling agent, 2-5 parts of curing agent, 20-50 parts of waste calcium carbonate, 30-50 parts of low-shrinkage additive and 3-8 parts of release agent.
As some alternative embodiments herein, the silane coupling agent comprises: the low-shrinkage polyethylene resin composition comprises at least one of a KH-550 coupling agent, a KH-560 coupling agent, an A-187 coupling agent, an A-1100 coupling agent and a JH-A110 coupling agent, wherein the curing agent is styrene, the low-shrinkage additive is one or more of polyethylene and polystyrene, and the release agent is zinc stearate.
In order to solve the above technical problem, the embodiment of the present application further provides: a preparation method of the glass fiber reinforced plastic material comprises the following steps:
preparing to obtain glue solution;
carrying out surface treatment on the glass fiber cloth by adopting plasma to obtain first glass fiber cloth;
and (3) dipping the first glass fiber cloth into the glue solution, and after full dipping, performing extrusion treatment to obtain the glass fiber reinforced plastic material.
As some optional embodiments of the present application, the preparing a glue solution includes:
mixing 90-120 parts of unsaturated polyester resin, 20-40 parts of boron nitride, 0.02-0.05 part of carbon nano tube, 0.01-1 part of silane coupling agent, 2-5 parts of curing agent, 20-50 parts of waste calcium carbonate, 30-50 parts of low shrinkage additive and 3-8 parts of release agent, uniformly mixing to obtain glue solution, and pouring the glue solution into an impregnation tank for later use.
As some optional embodiments of the present application, the surface treatment of the glass fiber cloth with plasma to obtain a first glass fiber cloth includes:
and baking the glass fiber cloth, and then putting the glass fiber cloth into a plasma machine for surface treatment for 3-7min to obtain first glass fiber cloth.
As some optional embodiments of the present application, the temperature of the baking treatment is 280-320 ℃ and the time is 8-12min.
As some alternative embodiments of the present application, the surface treatment working gas includes at least one of oxygen plasma, nitrogen plasma, and air plasma; the processing vacuum degree is 5-10Pa, the processing power is 180-220w, and the processing time is 3-8min.

The glue formulation was the same as in example 1.
Compared with the glass fiber reinforced plastic material obtained in the comparative example 1, the surface roughness of the glass fiber reinforced plastic material obtained in the above examples 1-3 is obviously increased, so that more effective action areas are formed between the glass fiber reinforced plastic material and the resin matrix, and the glass fiber reinforced plastic material is more beneficial to being soaked with the filler and the resin.
