And the solid masses of each component account for the size solid gross mass percentage it is as follows:
Also, the pH value control of the size is 2~7.
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 play the coupled action between glass fibre and matrix resin, on the one hand can reduce glass fibre in wire drawing
On the other hand the extent of damage in the process still influences the key of glass fiber strength and composite article intensity.
Common coupling agent is silane coupling agent, inventors discovered through research that, contain vinyl, metacryloxy, ammonia
Base or the coupling agent of epoxy group and film forming agent provided by the present application, lubricant cooperate, can effectively improve glass fibre with
The compatibility of resin.The solid masses accounting of coupling agent should not be too large, and the solid masses that the present invention limits coupling agent accounts for size
3~15%, preferably 5~15%, more preferably the 5~13% of solid gross mass.Further, inventor has found γ-methyl
Acryloyloxypropyltrimethoxysilane, gamma-aminopropyl-triethoxy-silane, γ-(2,3- glycidoxy) propyl front three
Oxysilane and vinyl three ('beta '-methoxy ethyoxyl) silane are highly suitable for the present invention, the infiltration prepared using the coupling agent
Agent, can make glass fibre composite article, and especially enhancing umbrella frame has better mechanical performance.
Most preferably, inventor is had found by numerous studies, and γ-methacryloxy third is used in above-mentioned coupling agent
Base trimethoxy silane and gamma-aminopropyl-triethoxy-silane progress compounding effect are best, glass fiber reinforced composite product tool
The standby bending strength being obviously improved, and unsuitable excessively high, the γ-ammonia of too high amount of content of gamma-aminopropyl-triethoxy-silane
Propyl-triethoxysilicane will lead to yarn and be hardened, and wetting-out rate is slack-off, most preferably, γ-methacryloxypropyl three
The solid masses of methoxy silane accounts for the 6~8% of size solid gross mass, the solid matter of gamma-aminopropyl-triethoxy-silane
Amount accounts for the 1~3% of size solid gross mass.
Lubricant is primarily to guarantee glass fibre in wire drawing, post-processing and the lubricant effect for the processes such as using.Profit
Lubrication prescription content is excessively few to be then not achieved lubricant effect, excessively will affect the caking property between precursor, reduce the stiffness of yarn so that
In will affect being impregnated in matrix resin and compatibility, the mechanical performance to final composite material is caused to have negative effect, this
The solid content of invention lubricant accounts for the 1~10% of size solid amount, and more preferable 1~8%.Lubricant of the present invention is selected
PEG series lubricant agent, PEG series lubricant agent have preferable emulsifiable property, water solubility and low surface tension, have good lubrication
Effect.It further, can inventors have found that PEG600, PEG1000 and PEG3000 high lubricating effect and molecular weight is smaller
Preferably meet the requirement of the high wetting-out rate of the present invention.
Film forming agent is the main component of size, plays conclusive influence to the processing performance of glass fibre, plays guarantor
The effect for protecting glass fibre, the compatibility for improving glass fibre and matrix resin, should guarantee glass fibre in pultrusion
Quick impregnability in technique guarantee again glass fibre and matrix resin compatibility and final composite article machinery it is strong
Degree, therefore, the selection of film forming agent is emphasis of the invention.
Common film forming agent have polyaminoester emulsion, polyester resin emulsion, polyvinyl acetate emulsion, acrylic acid ester emulsion and
Epoxy emulsion, inventor is by a large amount of the study found that film forming agent of the invention is suitble to only have polyester resin emulsion and epoxy cream
Liquid, other kinds of film forming agent can make yarn be hardened, and be unfavorable for the pultrusion molding process of reinforcing material.On the other hand, in this hair
In bright, in order to further increase the wetting-out rate of glass fibre, exceptionally except the necessary group such as coupling agent, lubricant, pH adjusting agent,
Should not be again containing other auxiliary agents such as antistatic agents, therefore, film former content is higher, and solid masses accounts for size solid amount
70~90%, preferably 72~90%, more preferably 75~90%.
Further, film forming agent of the present invention uses the compounded combination of polyester resin emulsion and epoxy emulsion, can meet infiltration
The coating requirement of agent, wherein the solid content of polyester resin emulsion accounts for the 10~80% of size solid amount, preferably 30~
50%；The solid content of epoxy emulsion accounts for the 10~80% of size solid amount, preferably 30~50%, more preferable 35~
50%.
The present invention also further has studied the molecular weight of film forming agent emulsion and the relationship of size performance, and invention is when use
When the agent emulsion molecular weight that forms a film is smaller, corresponding glass fiber yarn is soft, and convergence is poor, but wetting-out rate is fast；And use molecule
When measuring big lotion, corresponding glass fiber yarn is hard, and filoplume is more, and convergence is good, but wetting-out rate is partially slow.And it is unsaturated poly-
Ester resin emulsion plays a leading role on wetting-out rate, and epoxy resin latex convergence is very good, also, unsaturated polyester resin
The number-average molecular weight of lotion need to be greater than the number-average molecular weight of epoxy resin latex, the number-average molecular weight of Emulsion of UPR
It is 500~1000, preferably 800~1000, more preferable 850~1000；The number-average molecular weight of epoxy resin latex is 300~800,
It is preferred that 400~800.The present invention can guarantee that glass fibre possesses good convergence and impregnability using such combine, and draw
It extrudes in product and is uniformly dispersed, filoplume is few, is impregnated with fastly, product surface is smooth, also improves the mechanical strength of pultrusion product.
The present invention is used as pH adjusting agent using acid, and one of acetic acid, citric acid, hydrochloric acid and formic acid or more can be selected
Kind, mainly play a part of to adjust size pH value.The solid masses of pH adjusting agent account for size solid gross mass 0.5~
5%, preferably 1~4%.
The hydrolysis with dispersion of coupling agent need under certain pH environment in size, require to meet dispersion, this hair
Bright size need to control as slant acidity environment, and pH value is 2~7, preferably 3~6.Size provided by the invention makes glass
Glass fiber has good convergence and impregnability, is very suitable to the pultrusion molding process of glass fiber reinforced composite product, and
Composite article obtained, especially umbrella frame have excellent mechanical performance.Further, which is particularly suitable for alkali-free
The enhancing of glass fibre, composite article obtained can satisfy the demand of high-end customer.Therefore, the present invention also provides above-mentioned leachings
Moisten purposes of the agent on the pultrusion molding process of the enhanced umbrella frame of alkali-free glass fibre.
If it should be noted that instant component lotion or solution form, the solid masses of the component is after drying
The quality of remainder is the component of liquid or gas for solute, such as when pH adjusting agent is formic acid solution, solid masses
Then in nail acid solution solute formic acid quality.
Water in the present invention primarily serves the effect of each component in dispersion size, and the solid masses of size accounts for size
The 4~12% of gross mass, residual mass are then water, preferably deionized water.
Compared with prior art, the present invention its advantages are embodied in:
