The percentage for accounting for the size solid gross mass is as follows：
The effect of each component and content are described as follows in the size：
Coupling agent, also known as bridging agent, containing organic from inorganic two different functional groups, Inorganic functional groups can be with for its own
The hydroxyl of glass surface reacts, and another organo-functional group can react with enhanced matrix resin, serves as a connection.
The use of coupling agent can reduce the extent of damage of the glass fibre in drawing process, and the selection of coupling agent still influences glass
The key of glass fibre strength and glass fiber reinforced plastics product intensity.
The coupling agent that the present invention selects be silane coupling agent, common silane coupling agent have vinyl, metacryloxy,
Amino, epoxy group etc., inventors discovered through research that, vinyl three ('beta '-methoxy ethyoxyl) silane, three ethoxy of γ-aminopropyl
Base silane, γ-(2,3- glycidoxy) propyl trimethoxy silicane or polyamide-based silane can obviously reduce glass fibre
Wear intensity, and improve the compatibility of glass fibre and matrix resin.The solid masses accounting of coupling agent should not be too large, present invention limit
Determine coupling agent solid masses account for size solid gross mass 3~15%, preferably 6~14%, more preferably 8~12%,
Most preferably 8~10%.The size prepared using the coupling agent can protect glass fibre to reduce the extent of damage, and make glass
The direct yarn reinforcing material of glass fiber has better mechanical performance.
Lubricant is primarily to guarantee glass fibre in wire drawing, post-processing and the lubricant effect for the processes such as using.Leaching
Profit agent content is excessively few to be then not achieved lubricant effect, excessively will affect the convergence of glass fiber yarn, and will affect final glass
The mechanical performance of steel part.On the other hand, effect of the different lubricants in glass fibre production and use process is different, has dry
Lubrication and the difference for moistening cunning, have large effect using processing performance and mechanical performance to yarn.Therefore, lubricant composition and
The selection of content is an emphasis of the invention.
In the present invention, lubricant is compounded using two distinct types of lubricant, wherein lubricant A selects poly-
Glycols lubricant.Polyethylene glycol series lubricant agent can be reduced the abrasion in drawing process to yarn, while reduce yarn use
Frictional force in the process.Wherein, lubricant A solid masses account for size solid gross mass 3~11%, preferably 4~11%, more
It is preferred that 5~9%, most preferably 5~7%.
Lubricant B selects silicone emulsion series lubricant agent, and the type lubricant makes lubricant B more during yarn is rolled into a ball and baked
Yam surface mostly is moved to, reduces the frictional force in yarn use process, while reducing the adhesion between yarn, reduces and uses
Broken yarn probability in the process.Wherein, lubricant B solid masses account for size solid gross mass 2~12%, preferably 4~12%, more
It is preferred that 6~10%, most preferably 6~8%.
Preferably, lubricant A is one of PEG600, PEG1000, PEG2000 and PEG3000 or a variety of, lubricant B

The ratio between be 1:0.8~1.5, more preferably 1:1.0~1.2.The lubricant compounded using said components and ratio, glass fibre are compiled
The problems such as weaving process performance is best, can effectively improve glass wool yarn and nest like sleave, and the mechanical performance of composite material has
Bigger raising.
Main component of the film forming agent as size plays conclusive influence to the processing performance of glass fibre, plays
The effect for protecting glass, the compatibility for improving glass and matrix resin should guarantee that glass fibre production smoothness exists again
It can be uniformly mixed with enhanced matrix resin in later process, the selection of film forming agent is another emphasis of the invention.
Film forming agent of the invention selects epoxy emulsion, and preferably having selected different types of epoxy emulsion to carry out collocation makes
With can meet the coating requirement of size, reduce the migration during baking, preferably be coated in fiberglass surfacing.Epoxy
The solid masses of latex A accounts for the 35~65% of size solid gross mass, and preferably 35~60%, more preferable 40~60%, more
