Example Embodiment

[0025] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following embodiments are specially cited in conjunction with the drawings, and detailed descriptions are made as follows.
[0026] The stone plastic board of the present invention includes 70-75% stone powder, 10-15% plant fiber, 15-20% resin and 1-5% modifier.
[0027] A specific example is that the above-mentioned stone plastic board is grafted with 70% stone powder, 13% plant fiber, 15% polyethylene and 2% maleic anhydride by mass fraction of polypropylene.
[0028] Another embodiment is that the above-mentioned stone plastic board is grafted with polypropylene or organosilane with a mass fraction of 72% stone powder, 10% plant fiber, 15% polyethylene and 3% maleic anhydride.
[0029] Another example is that the above-mentioned stone plastic board is grafted with polypropylene or organosilane with 70% mass fraction of stone powder, 10% plant fiber, 15% polyethylene and 5% maleic anhydride.
[0030] Further, for the convenience of obtaining materials, the above-mentioned plant fiber is plant bast fiber, which is a single fiber or process fiber obtained from some plant phloem, such as flax, ramie, jute, and bamboo fiber; the modifier is maleic anhydride grafted Polypropylene or organosilane.
[0031] The production process of the stone plastic board of the present invention,
[0032] A. Pre-made stone powder: collect the powder produced by cutting the stone in the stone cutting factory, or crush small stones into powder, and further grind the powder to make the powder particle size 250-330 mesh, while ensuring the powder The moisture content is less than 6%;
[0033] B. Pre-fabrication of plant fiber: Roll the fresh whole bamboo into long pieces, then cut them into long pieces with a thickness of 1 cm along the length direction (the long pieces are placed vertically), and then the long pieces The flakes enter the crusher to be shredded into small pieces, and then enter the grinding disc for pressure grinding. The pressure of the pressure grinding is 120 kg per square centimeter, the grinding time is 2 minutes, and the relative rotation speed of the pressure grinding disc is 60 circles per minute. The material is ground into filaments and packed in a container and modified with maleic anhydride grafted polypropylene or organosilane;
[0034] C. Add the proportioned amount of stone powder and modified plant fiber into the mixing hopper, stir for 5 minutes at a speed of 150 turns per minute, and then add one-half of the proportioned amount of resin, and then add 200 turns per minute. Stir for 1 minute at a rotating speed of, and finally add a proportion of one-half of the resin to continue stirring at a rotating speed of 200 revolutions per minute for 2 minutes, and the preparation is complete;
[0035] D. Put the prepared materials into a melting furnace at 150-160 degrees Celsius to melt and mix, and then extrude the melted materials through a molding die, and then perform secondary water-cooling molding after extrusion.
[0036] The production equipment of the stone-plastic board of the present invention includes a bamboo rolling machine 5, a slicer 6, a crusher 7 and a disc grinder 9 which are connected in sequence. The rolling machine 5 consists of a frame 501 and two sets on the frame. It is composed of rollers 502 arranged in parallel and spaced apart, and the distance between the two rollers is 6 cm. The bamboo is fed from one side of the two rollers and discharged from the other side; the slicer 6 includes a high-speed rotating shaft 601, a rotating shaft 601 is horizontally arranged. The rotating shaft 601 is provided with metal circular saw blades 602 side by side and spaced at intervals. The diameter of the metal circular saw blades 602 is 15 cm. The metal circular saw blades are separated by a 1 cm thick collar 603. , The long pieces of bamboo enter from one side of the metal circular saw blade 602, and output from the other side; the crusher 7 includes a cylindrical barrel 701, the bottom of the barrel is provided with a high-speed rotating vertical rotating rod 702 , The upper end of the rotating rod 702 is provided with two rows of oblique knife groups 703. The oblique knife group 703 is three downwardly inclined blades uniformly arranged on the peripheral side of the rotating rod, with an inclination of 60 degrees, in a cylindrical cylinder The side of 701 has a feed port 704; the grinding disc machine 9 is composed of an upper movable grinding disc 901 and a lower fixed grinding disc 902. The contact surface of the upper movable grinding disc 901 and the lower fixed grinding disc 902 is provided with a strip-shaped groove 903. The V-shaped groove is a V-shaped groove. The opening width of the V-shaped groove of the upper movable grinding disc 901 is 0.6 cm, and there are 12 V-shaped grooves in the circumferential direction. The opening width of the V-shaped groove of the lower fixed grinding disc 902 It is 1 centimeter, has 12 V-shaped grooves in the circumferential direction, and has a feeding funnel 904 on the upper movable grinding disc 901.
[0037] The stone plastic board of the present invention includes a board body 1, the first side 101 of the board body 1 is provided with a first concave circular arc sheet 2 on the bottom surface, and the second side 102 of the board body is provided with another board that can be fastened on the bottom surface The second concave circular arc piece 3 of the first concave circular arc piece, the partial arc section of the first concave circular arc piece extends beyond the first side 101 of the plate body, and the second side edge of the plate body has a curve toward the bottom. The folding part 4 is pressed on the arc-shaped section of the first concave arc of another plate.
[0038] Further, for reasonable design, the circumferential angle at which the first concave arc piece is located is 160 degrees, and the center of the circle falls on the lower surface of the plate.
[0039] Further, for reasonable design, the circumferential angle at which the second concave arc piece is located is 170 degrees, and its center falls on the lower surface of the plate.
[0040] Further, a plurality of reinforcing ribs 8 in an inverted T shape are arranged on the bottom surface of the above-mentioned plate body located between two concave arcs.
[0041] Further, in order to facilitate positioning, a rectangular protrusion 10 is provided on the lower surface of the plate body beside the first concave arc piece to limit the lateral movement of the second concave arc piece of another plate.
