This invention provides a water-based coating for anti-slip and heat-resistant bamboo mats. The coating comprises a water-based penetrating primer layer, a water-based colored topcoat layer, a water-based water-resistant and heat-resistant coating, and a water-based anti-slip and wear-resistant coating. These four layers are sequentially applied to a bamboo substrate. This invention consists of four coating layers, which, when applied to a bamboo substrate, endow the bamboo product with excellent anti-slip, wear-resistant, water-resistant, and heat-resistant properties.

This utility model belongs to the field of LED display technology and discloses an outdoor LED grid display screen, including multiple LED light source emitters arranged in a grid array. Each LED light source emitter includes an emitter body and a light source emitting head. One side of the emitter body is a mounting surface and is mounted on a mounting frame. Multiple light source emitting heads are correspondingly embedded on the end face of the emitter body away from the mounting surface. The light emitted by the light source emitting heads is emitted horizontally in a wide-angle manner. Each light source emitter is equipped with a reflector located above the light source emitting head. One end face of the reflector is an inclined mirror surface, with its lower end abutting against the end face of the emitter body away from the mounting surface and its upper end away from this end face, so as to reflect part of the light emitted upwardly by the light source emitting head in a horizontal direction. This grid display screen can reduce the upward tilt of light and reflect it in a horizontal direction, thereby improving the brightness of the light and the clarity of the display screen.

This invention relates to a method for preparing a water-soluble yellow reactive dye, comprising: adding water and ice to 2-naphthylamine-3,6,8-trisulfonic acid and slurrying, followed by a diazotization reaction to obtain a diazo material; adding water and ice to m-ureidoaniline, adding an alkali agent, and stirring to dissolve and obtain a clear m-ureidoaniline solution; adding the diazo material to the clear m-ureidoaniline solution and performing a coupling reaction at a controlled temperature to obtain a yellow base; adding water and ice to cyanuric chloride, adding dispersant CS and dispersant MF and slurrying, then adding sodium 2,4-diaminobenzenesulfonate and mixing and slurrying, with staged heating and pH adjustment to react and obtain a bicondensed material; adding the yellow base to the bicondensed material, heating and adjusting the pH, and performing a controlled reaction to obtain a dye slurry. The preparation method provided by this invention features high chroma conversion rate, short production cycle, and reasonable and efficient process, resulting in a product with excellent solubility, high fixation rate, good storage resistance, and bright color.

This application discloses a linear anti-glare rear projection optical imaging film, comprising a substrate layer, a first adhesion-promoting undercoat layer, a second adhesion-promoting undercoat layer, a linear grating layer, and an imaging layer. The substrate layer has the first adhesion-promoting undercoat layer on one side and the second adhesion-promoting undercoat layer on the other side. The linear grating layer is disposed on the first adhesion-promoting undercoat layer, and the imaging layer is disposed on the second adhesion-promoting undercoat layer. The substrate layer is used to integrally support the linear grating layer and the imaging layer through the first and second adhesion-promoting undercoat layers, and is light-transmitting. The imaging layer is used for double-sided imaging. The linear grating layer is used to directionally refract the light source of the projector to resist glare. Therefore, it not only enables double-sided imaging but also directionally refracts the light source of the projector, achieving an anti-glare effect, resulting in clearer and more vibrant images.

This utility model discloses a color-reflective high-strength PVC sheet, relating to the field of PVC sheets. It includes a PVC substrate layer, with a color-reflective composite layer for reflecting colors disposed on one side of the PVC substrate layer. The color-reflective composite layer comprises a primer layer, a colored pigment layer, and a reflective layer stacked sequentially. A reinforcing layer for increasing the strength of the PVC substrate layer is disposed on the other side of the PVC substrate layer. This color-reflective high-strength PVC sheet, by incorporating the color-reflective composite layer composed of a primer layer, a colored pigment layer, and a reflective layer, allows for the formulation of a rich variety of colors to meet diverse decorative design needs. It enhances light reflection performance, making it suitable for applications requiring light reflection. Simultaneously, the reinforcing layer, while ensuring lightweight construction, enhances the sheet's tensile, bending, and impact resistance, reduces surface wear, and extends its service life, enabling it to adapt to more complex usage environments.

The application discloses a multifunctional color early-strength frequency-modulated molding mortar suitable for a DIY scene and a preparation method thereof, and belongs to the technical field of building materials, which comprises sulphoaluminate cement, machine-made sand, metakaolin, redispersible latex powder, water reducing agent, early-strength agent, suspension stabilizer, inorganic pigment, cellulose ether, defoaming agent, and the rest is water. The application adopts the multifunctional early-strength frequency-modulated molding mortar suitable for the DIY scene and the preparation method thereof, and realizes the super-early-strength performance through the cooperation of the sulphoaluminate cement and the early-strength agent, utilizes the physical-chemical cooperation of the redispersible latex powder and the metakaolin to make the hardened surface dense and smooth, the powder cannot be scraped off by a nail, and the migration of alkaline substances is blocked, thus preventing the efflorescence phenomenon, and the operable time is controlled within 30-60 minutes, which avoids the too fast invalidation and takes into account the early-strength development, and solves the problems of a long maintenance period, water sensitivity, powder dropping and efflorescence of a finished product and single color of the traditional DIY cement.
