The invention relates to a low-smoke halogen-free EPDM rubber composition and a preparation method, comprising the following components in parts by weight: 100 parts of EPDM rubber; 50-100 parts of an intumescent halogen-free flame retardant; 5 parts of a filler ~15 parts; 2 to 4 parts of vulcanization assistant; 1 to 3 parts of anti-aging agent. Compared with the prior art, the flame-retardant EPDM rubber prepared by the present invention has low smoke and no halogen, reaches the UL94 (1.6mm) V-0 level, and has good mechanical and mechanical properties. At the same time, the product is white and can be toned. The application of flame retardant rubber in automobiles, electronic appliances, construction and other fields.

The invention provides a glass fiber reinforced nylon composite material. The composite material is prepared from the following components in percentage by weight: 35-66.8 percent of nylon resin, 30-60 percent of chopped glass fibers, 2-15 percent of nano-phyllosilicate, 1-5 percent of compatilizer, 0.1-1 percent of a lubricating agent and 0.1-1 percent of antioxidant. According to the glass fiber reinforced nylon composite material, the nano-phyllosilicate filler and glass fibers are used for synergically reinforcing, advantages of a glass fiber reinforced nylon composite material are maintained, the strength and toughness of the composite material are further improved, the defects of poor size stability, poor surface and the like of the material caused by reinforcing adopting high glass fiber content can be overcome, and the color of the material is little influenced. Furthermore, the glass fiber reinforced nylon composite material has excellent mechanical performance and good fluidity, and can be applied to manufacture of machinery and automobile parts requiring high strength.

The invention relates to a 3D printing light-curing color-changing indicating resin and a 3D printing method. The light-curing color-changing indicating resin for 3D printing comprises the following components in parts by weight: 20-40 parts of oligomers; 10-20 parts of monomers; diluted 20-50 parts of the photoinitiator; 1-5 parts of the photoinitiator; 0.1-3 parts of the light indicator; wherein, the light indicator is a nitrogen-containing acrylate monomer, a nitrogen-containing compound, etc., which have a similar potential light indicating effect. A 3D printing method, using the above 3D printing photocurable color-changing indicator resin as a 3D printing photosensitive resin; the 3D printer light source is ultraviolet light with a wavelength of 280-420nm; the secondary curing light source is ultraviolet light with a wavelength of 280-420nm. In the present invention, by adding a "light indicator" into the photosensitive resin, the appearance of the material presents obvious differences before and after secondary curing, thereby effectively avoiding the problems of multiple curing and no secondary curing of the material.

The application provides an obstacle handling method and a cleaning robot. Wherein, the cleaning robot includes a controller, an image acquisition device, a fuselage main body and a side sweep, and the side sweep extends beyond the edge of the fuselage main body; image; the controller is used to, according to the first image of the obstacle, identify the type of the obstacle; determine the obstacle handling method corresponding to the obstacle type, and the obstacle handling method includes whether the cleaning robot moves ahead according to the The direction continues to move forward, and when the cleaning robot changes its forward direction in front of the obstacle, the distance information between the main body of the fuselage and the side scan and the obstacle respectively; the controller is used to control the obstacle handling method corresponding to the type of obstacle Clean robot movement. The implementation of this application can improve the cleaning coverage for different obstacles and reduce the risk of cleaning.

The invention relates to a nylon composite material which comprises the following components in percentage by weight: 24.4-57.4% of nylon resin, 35-60% of chopped glass fiber, 5-15% of modified nano boehmite, 2-5% of compatilizer, 0.1-1% of lubricant and 0.1-1% of antioxidant. The glass-fiber-reinforced nylon composite material has the characteristic of high strength. The modified nano boehmite and glass fibers are used for synergic reinforcement, thereby maintaining the advantages of the glass-fiber-reinforced nylon composite material, enhancing the strength and toughness of the material, overcoming the defects of poor dimensional stability and surface defects of the material due to high glass fiber content and having small influence on the material color. The nylon composite material has the advantages of excellent mechanical properties and favorable flowability, and is applicable to manufacturing of machines and automobile parts in need of high strength.

The invention provides a color filter substrate and a display device, which include a plurality of pixels arranged in an array, each pixel includes three color photoresists with different colors, and a row of pixels includes three parallel rows of colored photoresists. Resist row, the color photoresist rows on both sides include two colors of color photoresist, and the two colors of color photoresist are arranged at intervals. In the above-mentioned color filter substrate, in a pixel unit composed of four pixels, the color photoresist of one color is adjacent to the color photoresist of two colors on the left side or the right side, when the color filter substrate is opposite to When the array substrate is shifted left and right and the picture is observed along an oblique viewing angle, a sub-pixel of one color will be inserted into the other two colors, and the two colors inserted in the series will be superimposed on the color of the sub-pixel itself to display the sub-pixel The influence of color is much smaller than that of a single color, which solves the problem of cross-color caused by poor alignment between the color filter substrate and the array substrate, and improves the picture quality.
