Technical Field

[0001] This invention relates to the field of silane coupling agent production technology, specifically to an apparatus and method for producing an aqueous epoxy silane coupling agent. Background Technology

[0002] Silane coupling agents are substances containing functional groups with different properties. They serve as an intermediate bridge connecting organic and inorganic substances. Silane coupling agents can be classified into methacryloyloxy, amino, epoxy, vinyl, and other silanes according to the type of functional group. They are widely used in industries such as solar photovoltaic, glass fiber, sealants, coatings, and plastics.

[0014] A method for using an apparatus for producing an aqueous epoxy silane coupling agent includes the following steps:

[0015] Step 1: Add a certain amount of epoxy silane coupling agent to the reaction vessel, then prepare an alcohol / water / acid solution according to the ratio and store it in a dropping tank;

[0016] Step 2: Add a certain amount of alkylsilane coupling agent, ethanol and deionized water to the inside of the solvent storage tank, add alkylsilane coupling agent and ethanol to the reaction vessel in proportion, and add a certain amount of polymerization inhibitor to the reaction vessel at the same time, and stir evenly.

[0017] Step 3: Add alcohol / water / acid solution dropwise, controlling the dropping rate at 1 d / s and the temperature not exceeding 60℃. After the addition is complete, keep the reaction at this temperature for 6-8 hours.

[0018] Step 4: After the reaction is complete, reduce the pressure to remove low-boiling-point substances, add a certain amount of deionized water and surfactant, and continue to keep the reaction at the temperature for 2-3 hours. After the reaction is complete, adjust the pH of the solution to neutral using a pH adjuster.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention is prepared by hydrolysis condensation polymerization, which is simple, produces readily available products with high yield, has no by-products, and exhibits good product stability. When applied to the water-based coatings industry, an addition of approximately 1% can significantly improve the system's adhesion, water resistance, and curing speed. It also has no VOC residues, meeting green environmental protection requirements.

[0021] 2. In this invention, the pressurization port at one end of the top of the dripping tank is connected to an air pump. During use, the air pump delivers pressure to the pressurization port through a pipe. Simultaneously, the liquid inside the dripping tank enters the electromagnetic reversing valve under the influence of internal and external pressure. Then, the solvent inside is delivered to the dripping valve through the output port. During the pressurization process, some of the pressurized air enters the dripping tank. As the liquid volume inside the dripping tank decreases, the air pressure in the pipe also decreases, but the gas volume inside the tank increases. Therefore, during subsequent dripping operations, the pressurization pressure cannot be maintained. Precise calculations can affect the dripping rate. The cooperation between the support valve plate and the buffer valve plate helps to coordinate the pressure inside the tank. When the air pressure enters the tank, the excess will push the buffer valve plate upward. During this process, the spring shaft will play a counter-pushing role, so that there is a certain resistance to the rise of the buffer valve plate. This can expand the pressure range and thus keep the pressure inside the tank at a stable standard value, ensuring the dripping rate. At the same time, the staff can also judge the pressure inside the tank by the rise of the buffer valve plate.

[0022] 3. In this invention, the solvent storage tank is composed of three independent pressurized tanks. Each tank has a discharge port and a collection port on both sides of its bottom. The discharge port is connected to the horizontally placed reactor through a feed pipe. The solvent enters the pressurized chamber through the collection port. Then, the motor drives the internal drive shaft and vortex vane to rotate at high speed. The centrifugal force generated by the rotation of the vortex vane accelerates the solvent input at the collection port to the discharge port, so that the solvent enters the interior of the reactor through the pipe.

[0034] The solvent storage tank 3 is composed of three independent pressurized tanks 301. Each tank has an outlet 303 and a collection port 302 on both sides of its bottom. The outlet 303 is connected to the horizontally placed reactor 1 through a feed pipe 3031. The solvent enters the pressurized chamber 3012 through the collection port 302. Then, the motor drives the internal drive shaft 3042 and the vortex vane 3041 to rotate at high speed. The centrifugal force generated by the rotation of the vortex vane 3041 accelerates the solvent input at the collection port 302 to the outlet 303, so that the solvent enters the interior of the reactor through the pipe.

[0035] Please see Figure 5-6 A connecting pipe 2011 is installed above the dripping tank 2, which is connected to a solenoid directional valve 201 via the connecting pipe 2011. One end of the solenoid directional valve 201 has a pressurization port 202, and the other end has an output port 203. The output port 203 is connected to the dripping valve port 102 via a flange. A pressure buffer valve 204 is installed on one side of the solenoid directional valve 201, and is connected to the dripping tank 2 via the connecting pipe 2011. The pressure buffer valve 204 includes a transition valve seat 2041, and a manual pressure relief valve 2043 is installed on one side of the transition valve seat 2041. The manual pressure relief valve 2043 and the transition valve seat 2041 are integrated. The structure includes a pressure buffer valve 204 with a transition valve seat 2041 at the bottom, which is connected to the through pipe 2011 via an internal thread. A pressure measuring pipe 2042 is provided on one side of the transition valve seat 2041, extending into the interior of the dripping tank 2. A support valve plate 2044 is provided above the transition valve seat 2041, and the support valve plate 2044 and the transition valve seat 2041 are integrated. A buffer valve plate 2045 is provided above the support valve plate 2044, and a spring shaft bracket 2046 is provided above the buffer valve plate 2045. The spring shaft bracket 2046 is connected to the support valve plate 2044, and the buffer valve plate 2045 is slidably connected to the spring shaft bracket 2046.

[0036] The pressurization port 202 at one end of the top of the dripping tank 2 is connected to an air pump. During use, the air pump delivers pressure into the pressurization port 202 through a pipe. Simultaneously, the liquid inside the dripping tank 2 enters the solenoid reversing valve 201 under the influence of internal and external pressure. Then, the solvent inside is delivered to the dripping valve port 102 through the output port 203. During the pressurization process, some of the air pressure enters the dripping tank 2. As the liquid volume inside the dripping tank 2 decreases, the air pressure in the pipe also decreases, but the gas volume inside the tank increases. Therefore, the pressurization pressure cannot be accurately calculated during subsequent dripping operations. This can affect the dripping rate. However, the cooperation between the support valve plate 2044 and the buffer valve plate 2045 can help coordinate the pressure inside the tank. When the air pressure enters the tank, the excess will push the buffer valve plate 2045 upward. During this process, the spring shaft 2046 will play a counter-pushing role, so that there is a certain resistance to the rise of the buffer valve plate 2045. This can expand the pressure range and thus keep the pressure inside the tank at a stable standard value, ensuring the dripping rate. At the same time, the operator can also judge the pressure inside the tank by the rise height of the buffer valve plate 2045.

[0037] A method for using an apparatus for producing an aqueous epoxy silane coupling agent includes the following steps:

[0038] Step 1: Add a certain amount of epoxy silane coupling agent to reaction vessel 1, and then prepare an alcohol / water / acid solution according to the ratio and store it in dropper 2;

[0039] Step 2: Add a certain amount of alkylsilane coupling agent, ethanol and deionized water to the inside of solvent storage tank 3 respectively. Add alkylsilane coupling agent and ethanol to the reaction vessel in proportion. At the same time, add a certain amount of polymerization inhibitor to the reaction vessel and stir evenly.

[0040] Step 3: Add alcohol / water / acid solution dropwise, controlling the dropping rate at 1 d / s and the temperature not exceeding 60℃. After the addition is complete, keep the reaction at this temperature for 6-8 hours.

[0041] Step 4: After the reaction is complete, reduce the pressure to remove low-boiling-point substances, add a certain amount of deionized water and surfactant, and continue to keep the reaction at the temperature for 2-3 hours. After the reaction is complete, adjust the pH of the solution to neutral using a pH adjuster.

[0042] Working principle: A certain amount of epoxy silane coupling agent is added to reaction vessel 1, and then an alcohol / water / acid solution is prepared according to the ratio and stored in dropping tank 2. Meanwhile, a certain amount of alkyl silane coupling agent, ethanol, and deionized water are added to the solvent storage tank 3. Alkyl silane coupling agent and ethanol are added to the reaction vessel according to the ratio, and a certain amount of polymerization inhibitor is added simultaneously. The mixture is stirred evenly, and then the alcohol / water / acid solution is added dropwise. The pressurization port 202 at one end of the top of dropping tank 2 is connected to an air pump. During use, the air pump supplies gas to the pressurization port 202 through a pipeline. 2. Internal pressure is supplied. Simultaneously, the liquid inside the dripping tank 2, under the influence of internal and external pressure, enters the electromagnetic reversing valve 201. Then, the solvent is supplied to the dripping valve 102 through the output port 203. During pressurization, some gas pressure enters the dripping tank 2. As the liquid volume inside the dripping tank 2 decreases, the gas pressure in the pipe also decreases, but the gas volume inside the tank increases. During subsequent dripping operations, the pressurization pressure cannot be accurately calculated, leading to a decrease in the dripping rate. The rate is affected, but the cooperation of the support valve plate 2044 and the buffer valve plate 2045 can help coordinate the pressure inside the tank. When the gas pressure enters the tank, the excess will push the buffer valve plate 2045 upward. During this process, the spring shaft 2046 will play a counter-pushing role, so that there is a certain resistance to the rise of the buffer valve plate 2045. This can expand the pressure range, thereby maintaining the pressure inside the tank at a stable standard value and ensuring the delivery rate of the drip. At the same time, the staff can also judge the pressure inside the tank by the rise height of the buffer valve plate 2045. After the reaction is completed, the pressure is reduced to remove low-boiling-point substances, and a certain amount of deionized water and surfactant are added to continue the reaction at a constant temperature for 2-3 hours. After the reaction is completed, the pH of the solution is adjusted to neutral with a pH adjuster. It is prepared by hydrolysis condensation method. The process is simple, the product is easy to obtain and has a high yield, no by-products, and good product stability. It is applied in the water-based coating industry. The addition of about 1% can greatly improve the adhesion, water resistance and curing speed of the system. There is no VOC residue, which meets the requirements of green environmental protection.
