This utility model relates to the field of thick film heater technology and discloses a sealing structure for a thick film heater. In use, the external water supply pipe is first inserted into the inlet end and tightened via the connecting thread. The water supply pipe then compresses the sealing gasket, causing a telescopic spring to contract the gasket, thus separating the gasket from the sealing block. This allows water to flow into the thick film heater from the inlet end. The telescopic spring also pushes the sealing gasket against the end of the water supply pipe, improving the sealing effect and preventing water from flowing out through the gap between the water supply pipe and the inlet end. When the external water supply pipe ages and breaks and needs replacement, it can be removed. When the water supply pipe is removed, the telescopic spring causes the sealing gasket to reset, causing it to abut against the sealing block and seal the inlet end, preventing hot water from flowing out during replacement and causing injury. This improves the practicality of the sealing structure of the thick film heater.

Baffles are provided on both sides of the top of the bottom plastic profile. This application enhances the connection strength between the top plastic profile and the middle aluminum profile by providing connecting components, and enhances the connection strength between the bottom plastic profile and the middle aluminum profile by providing support components, thereby improving the wind pressure resistance and strength of the aluminum-plastic door and window, and increasing the stability and service life of the door and window.

This invention discloses a water-based coating with fire-retardant and thermal insulation functions, its preparation method, and its application, relating to the field of water-based coatings. This water-based coating with fire-retardant and thermal insulation functions, through an innovative raw material ratio, combines inorganic and organic flame retardants, along with surface-treated insulating glass microspheres and a specific ratio of inorganic hybrid emulsion, successfully enabling the coating to simultaneously possess excellent fire-retardant and thermal insulation properties. Test results of Examples 1-3 show that the coatings all achieve a 1-hour fire resistance rating, with the lowest thermal conductivity reduced to 0.042 W / (m·K), far exceeding the performance of the control example, which only possesses basic fire-retardant functions and insufficient thermal insulation performance. When this multifunctional coating is applied to building exteriors, industrial equipment surfaces, and vehicle interiors, it can effectively prevent the spread of fire, ensure personnel safety, reduce energy consumption, and improve energy efficiency.
