Description

Technical Field

[0001] The invention relates to methyl silicone oil-based quartz fiber joint glue and a preparation method thereof. Background Art

[0002] Quartz fiber is a woven material used for textile, weaving, and three-dimensional weaving. It can be made into quartz fiber yarn, which has high strength, high temperature resistance, heat insulation, electrical insulation, and good chemical stability. It has a wide range of applications in high temperature resistance, heat insulation, filtration, and flame retardancy. Quartz fiber yarn can be woven into quartz fiber cloth, belts, sleeves, etc., and can also be used as a reinforcing material for composite materials.

[0003] However, quartz fiber yarn also has the disadvantages of being brittle and not wear-resistant, especially during processing, it is easy to wear and break, which leads to yarn fuzzing and reduced strength. Therefore, quartz fiber yarn often breaks during processing, which requires the use of special joint glue to connect quartz fiber yarn.

[0004] However, the current quartz fiber factories, glass fiber factories and basalt fiber factories use traditional dibutyl phthalate type joint glue, which has a complex formula, high cost, and is toxic. It will pollute the environment and endanger the health of workers. More importantly, its bonding force is not very strong and the penetration speed is slow. The surface flatness of the quartz fiber bonded with it is poor, and there is color difference after bonding, especially after it is made into a composite material, there is color difference at the bonding point of the yarn, which affects the product quality.

[0005] On the other hand, dibutyl phthalate has been banned by the European Union because it has been identified as an environmental hormone that can cause cancer in animal liver tissue and disrupt the endocrine system. When it is subsequently incinerated, it will release large amounts of chlorine, vinyl chloride, dioxins and other toxic substances. Summary of the invention

[0006] The purpose of the present invention is to provide a quartz fiber joint glue based on methyl silicone oil, which is non-toxic, has strong bonding strength, fast penetration, low cost and good flatness; the purpose of the present invention is also to provide a preparation method of the above-mentioned quartz fiber joint glue based on methyl silicone oil.

[0007] In a first aspect, the present invention provides a quartz fiber joint glue based on methyl silicone oil, which adopts the following technical scheme: quartz fiber joint glue based on methyl silicone oil, wherein the joint glue is made of the following raw materials in percentage by mass: 60-85% of dissolving agent; Methyl silicone oil 4-12%; Polymethyl methacrylate molding powder 10-25%.

[0008] When the methyl silicone oil-based quartz fiber joint glue of the present invention is used to make joints of quartz fiber products, the methyl silicone oil can react physically and chemically with the polymethyl methacrylate molding powder, and under the dissolving action of the dissolving agent, a colorless and completely transparent viscous colloid is formed. The glue itself is non-toxic, does not pollute the environment, does not harm the health of workers, and the material is easy to obtain, and the cost is significantly reduced. Due to the completely colorless and transparent characteristics, the color of the bonded quartz fiber will not be increased or changed, so the quartz fiber products bonded by the glue have no color difference. Furthermore, due to the effective effect of the methyl silicone oil on the lubrication and softening of the polymethyl methacrylate molding powder, the overall bonding force of the glue is significantly enhanced, and the permeability is also significantly improved. At the same time, after the bonding is solidified, the surface of the product is very smooth and has good flatness. Moreover, if it is accidentally left on the hands, it is also very convenient to clean up due to its non-sticky characteristics.

[0009] Preferably, the methyl silicone oil is 201 methyl silicone oil. The polymethyl methacrylate molding powder is 613 polymethyl methacrylate molding powder.

[0010] Preferably, the viscosity of the dissolving agent is 2-5 cps, and the effective substance is ≥35%.

[0011] Preferably, the viscosity of the 201 methyl silicone oil is 100±8mm² / s, and contains 97-103% polymerized dimethylsiloxane.

[0012] Preferably, the 613 polymethyl methacrylate molding powder is in powder form, and the PMMA microsphere particle size is 250-300 mesh.

[0013] In the second aspect, the technical scheme of the preparation method of the quartz fiber joint glue based on methyl silicone oil of the present invention is as follows: Add a set amount of dissolving agent into the preparation barrel and stir; Slowly add the set amount of methyl silicone oil into the preparation barrel and stir for 5 minutes; Slowly add a set amount of polymethyl methacrylate molding powder into the preparation bucket and stir continuously until the polymethyl methacrylate molding powder is completely dissolved, no white particles are left, and the solution is completely transparent and viscous.

[0014] Compared with traditional joint glue, its preparation process is very simple, and because it is non-toxic and does not require closed operation, the operation is very convenient and fast, and the preparation efficiency is relatively high.

[0015] In summary, the present application has the following beneficial effects: non-toxic, low odor, simple and easy to obtain formula, low cost, convenient configuration and operation, no pollution to the environment, no harm to human health, strong adhesion to quartz fiber yarn, fast penetration speed, non-sticky, good surface smoothness of the bonded quartz fiber product, no color difference at the bonding point after resin penetration compared with the color of quartz fiber, and no obvious color difference after being made into a composite material.
