Description
Technical Field
The application relates to the technical field of glass fiber electronic cloth production, in particular to a treating agent for glass fiber electronic cloth, and a preparation method and application thereof.
Background
The glass fiber electronic cloth is an electronic grade glass fiber cloth mainly applied to the field of electronic products. The glass fiber electronic cloth is formed by interweaving glass fiber yarns in the warp-weft direction, and after secondary desizing, the surface of the glass fiber electronic cloth is coated with a special treating agent to improve the binding capacity of the glass fiber electronic cloth with downstream resin. The glass fiber electronic cloth is combined with resin, copper foil and the like to prepare the copper-clad plate, is a basic raw material of a printed circuit board, and is widely applied to various fields of electronic communication, smart phones, computers, household appliances and the like.
Since the glass fiber cloth is made of an inorganic nonmetallic material such as silica, and has a weak binding ability with organic substances such as resin, and thus has no function, it is necessary to perform a surface treatment to improve the reactivity of the surface of the glass fiber. At present, the glass fiber electronic cloth is mainly treated by using a coupling agent in the industry, one end of the coupling agent is a silicon hydroxyl group which can be well bonded with the surface of the glass fiber, and the other end of the coupling agent is an organic functional group which has good affinity with resin.
At present, various domestic manufacturers have studied the treating agent for the glass fiber electronic cloth very deeply, and various application schemes are provided aiming at different application requirements. The existing glass fiber electronic cloth treating agent scheme can effectively improve mechanical properties of wear resistance, folding resistance and the like of products and improve heat resistance and ion migration resistance of electronic cloth, but the problems of insufficient stability of the treating agent, long impregnation time, more emission of acid gas in the using process, short humidity resistance and the like exist, and further solution is needed.
With the increasing requirements of the market on the product quality, the environmental protection supervision of enterprises is getting stricter. The importance of solving the above problems is increasingly prominent.
In order to improve the impregnation speed of the glass fiber electronic cloth, improve the humidity and heat aging resistance of the product and reduce the emission of acid gas in the production process, a novel treating agent needs to be developed, so that the glass fiber electronic cloth and the product prepared by coating the glass fiber electronic cloth can obviously achieve the purpose in production, and the requirements of production and market are better met.

Preferably, the defoaming agent is one or a mixture of any more of polysiloxane, polyoxyethylene ether and fatty acid ester.
The prehydrolysis liquid has the effect of improving the stability of the coupling agent in water; the prehydrolysis liquid is a mixture of prehydrolysis liquid A and prehydrolysis liquid B; wherein the prehydrolysis liquid A is prehydrolyzed by vinyl silane coupling agent, and under the action of oxalic acid and water, the silane coupling agent can be hydrolyzed to produce silanol. The other end of the vinyl silane coupling agent is a vinyl functional group which can perform addition reaction with unsaturated functional groups in downstream resin, so that the bonding strength between the resin and the electronic cloth is improved, and the wet heat and aging resistance of the product can be improved. The dosage of the prehydrolysis liquid A needs to be controlled in a proper range; when the dosage is too much, the coupling agent can form ineffective adsorption on the surface of the glass fiber; too little amount results in less bonding points between the glass fiber and the resin and insufficient bonding strength. The mass percentage of the prehydrolysis liquid A used in the method accounts for 0.1-0.7% of the total mass of the treating agent, and preferably 0.2-0.6%.
The vinyl silane coupling agent can be one or a mixture of any more of vinyl trimethoxy silane, vinyl triethoxy silane and vinyl tri (2-methoxyethoxy) silane.
In addition, the application further improves the using effect of the treating agent by controlling the weight ratio of the vinyl silane coupling agent, the oxalic acid and the water. Wherein when the weight ratio of the vinyl silane coupling agent to the oxalic acid to the water is (10-20) to (1-3) to (3-9), the using effect of the treating agent is better in all aspects. Preferably, the weight ratio of the vinyl silane coupling agent to the oxalic acid to the water is (12-18): (1-2): 4-8).
The prehydrolysis liquid B is prehydrolyzed by an epoxy silane coupling agent. The epoxy group and the vinyl group have different reactivity, and can widen the reaction window with downstream resin by matching, improve the impregnation performance of the glass fiber electronic cloth, and further improve the humidity and heat aging resistance of the product. The dosage of the prehydrolysis liquid B also needs to be controlled within a proper range; too much amount of the coupling agent can also cause ineffective adsorption of the coupling agent on the surface of the glass fiber; too little amount results in a narrow reaction window between the resin and the glass fibers. The mass percentage of the prehydrolysis liquid B used in the method accounts for 0.1-0.7% of the total mass of the treating agent, and preferably 0.2-0.6%.
Wherein the epoxy silane coupling agent is an epoxy hydrocarbon silane coupling agent, and specifically is one or a mixture of any more of gamma- (2, 3-epoxypropoxy) propyl trimethoxy silane, gamma- (2, 3-epoxypropoxy) propyl triethoxy silane and gamma- (2, 3-epoxypropoxy) propyl methyl dimethoxy silane.
Meanwhile, the application further improves the use effect of the treating agent by controlling the weight ratio of the epoxy silane coupling agent, the oxalic acid and the water. When the weight ratio of the epoxy silane coupling agent to the oxalic acid to the water is (5-15) to (1-3) to (3-9), the using effect of the treating agent is good; preferably, the weight ratio of the epoxy silane coupling agent to the oxalic acid to the water can be (8-12) to (1-2) to (4-8).
The acidity regulator serves to regulate the acidity of the solution. The acidity regulator is oxalic acid or/and malic acid. Illustratively, it may be oxalic acid. Conventional acidity regulators, such as glacial acetic acid, have a relatively low boiling point and tend to emit large amounts of acid gases during the production process. The oxalic acid or malic acid used by the acidity regulator has relatively high boiling point, is not easy to volatilize in the production process, can be further recycled in the form of aqueous solution, and improves the environmental protection property. The dosage of the acidity regulator must be controlled, and if the dosage of the acidity regulator is too much, equipment is corroded and the environment is polluted; if too small, the stability of the treatment agent may be impaired. The mass of the acidity regulator used in the method accounts for 0.4-1.0% of the total mass of the treating agent; preferably 0.5 to 0.9%.
The surfactant can improve the permeation speed of the treating agent, and ensure that the treating agent can be uniformly covered on the surface of the glass fiber electronic cloth in a short time at a high production speed. The surfactant is preferably one or a mixture of any of sodium alkyl sulfonate, sodium alkyl aryl sulfonate and sodium alkyl sulfate. More preferably, the surfactant can be sodium alkyl sulfonate, and further preferably, the surfactant can be one or a mixture of any of sodium dodecyl sulfonate, sodium tetradecyl sulfonate and sodium lauryl sulfate; illustratively, the surfactant may be sodium lauryl sulfate. The amount of surfactant must also be controlled within a suitable range: excessive use amount can generate a large amount of foam in the production process, thereby causing secondary pollution; too little results in insufficient penetration rate of the treating agent. The mass of the surfactant used in the method accounts for 0.03-0.09% of the total mass of the treating agent; preferably 0.04 to 0.08 percent.
In the production process of the electronic cloth, because the speed of the electronic cloth is high, a large amount of bubbles can be generated in the size tank, and the cloth cover pollution is easily caused. The present application therefore incorporates an anti-foaming agent in the treatment agent to reduce the generation of foam during production. Wherein, the defoaming agent can be one or a mixture of any more of polysiloxane, polyoxyethylene ether and fatty acid ester. Preferably, the defoaming agent may be polysiloxane. Specifically, polydimethylsiloxane or/and polymethylphenylsiloxane may be used. The amount of defoamer must also be controlled within the appropriate range: the excessive use can destroy the hydrophilic-lipophilic balance value of the formula and reduce the stability of the treating agent; if too small, the defoaming effect is not obtained. The mass of the defoaming agent used in the method accounts for 0.02-0.08% of the total mass of the treating agent; preferably 0.03 to 0.07%.
The water herein functions as the dispersed phase of the components of the treatment, preferably deionized water.

2S: and slowly adding the prehydrolysis liquid A, the prehydrolysis liquid B, the surfactant and the defoaming agent into the acidity regulator aqueous solution in sequence, and uniformly stirring to obtain the glass fiber electronic cloth treating agent.
