Composite brick machine supporting plate and manufacture method thereof
Technical field
The present invention relates to the special-purpose supporting plate and the manufacture method thereof of a kind of machine brick (exempting from fired brick), especially relevant with composite brick machine supporting plate and manufacture method thereof.
Background technology
Machine brick supporting plate mainly contains traditional wood plywood, bamboo plywood and PVC plate etc. in the market, the suction easily of wood plywood and bamboo plywood, aliquation, cracking, distortion, the loose machine brick quality that influences of quality after not only normally service time, weak point but also supporting plate made moist; The PVC plate is filled a large amount of inorganic material for reaching certain rigidity and dimensional stability, (is generally 1.8G/CM than great
3About), use the labour intensity height, quality is crisp firmly, rupture when the moulding of machine brick is shaken easily etc., and cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of waterproof, protection against the tide, corrosion-resistant, utilize waste or used plastics, production cost is low, the composite brick machine supporting plate and the manufacture method thereof of bending strength and integral smoothness height, long service life.
For achieving the above object, the present invention realizes by following technical solution: composite brick machine supporting plate, comprise supporting plate framework and the composite filled body formed by central layer, connection box and hasp, hasp is fixed on the connection box, central layer is embedded in the hasp, leave between connection box and the central layer and be connected the space, composite filled body is coated on about central layer and the connection box, reach all around and connect in the space.
Described composite brick machine supporting plate, a kind of framework of its connection box for being welded by hollow steel pipe has filler opening on hollow steel pipe, and the material of composite filled body is filled in hollow steel pipe inside by filler opening.
Described composite brick machine supporting plate, its central layer is wooden boards, bamboo lumber, glued board, particieboard, position plate, bamboo and wood or straw density board, the material of composite filled body is a major ingredient for the thermoplasticity waste or used plastics such as PP, PE with recycling, be equipped with material modified, inorganic matter or strings such as wood chip, stalk such as powder filler coal ash alone or in combination, the modified composite material that forms through fusion.
A kind of method of making described composite brick machine supporting plate is: the making of a, supporting plate framework: the edge inboard that hasp is fixed on connection box, central layer is embedded in the hasp, between connection box and central layer, leave and be connected the space, then the supporting plate framework is placed in the mould; The preparation of b, composite filled body: the preparation of composite filled body is decided according to the requirement of follow-up moulding process, follow-up moulding process is divided into colds pressing and two kinds of hot pressing, for adopting cold-press process, broken reclaimed materials or particulate material and filler are placed in the special-purpose homogenizer, be equipped with material modified, after high speed is mixing, melt extrude into bulk, be incubated standby getting final product through plastic extruder; For adopting heat pressing process, it is standby to melt extrude the back pelletizing as stated above; The compression moulding of c, composite brick machine supporting plate: compression moulding technology is divided into colds pressing and two kinds of hot pressing, the employing cold-press process, directly with the composite filled body of the bulk for preparing, place above the supporting plate framework in the mould, in hydraulic press normal temperature compression moulding, deburring after the demoulding; To adopting heat pressing process, with the granular composite filling material for preparing, evenly be layered on around the supporting plate framework reaches up and down, in hot press heating pressurization, compacting forms.
The manufacture method of described composite brick machine supporting plate is offered filler opening on the hollow steel pipe of forming connection box, the material of composite filled body is filled in the hollow steel pipe by filler opening in compacting.
The present invention has been owing to adopted technique scheme, thereby has following beneficial effect.(1) is because the built-in custom-designed steel framework of this supporting plate, improved bending strength, impact strength and the integral smoothness of supporting plate, avoided that common plastics sheet material bending strength is low, the defective of easy deflection deformation; (2) be because this product is a sandwich material with sheet materials such as bamboo and wood, stalks, reduced the use amount of plastics in the product, increased substantially the dimensional stability of product, and effectively reduced product cost; (3) be because the metal connection box in this framework and strengthen sheet material and be entirely modified plastics and coat in the described formed product process of invention, product has good waterproof, protection against the tide and corrosion resistance, has greatly improved product service life; (4) be because the material of composite filled body not only covers around central layer and the connection box, be filled in simultaneously to connect to reach in the space and be filled in the hollow steel pipe by filler opening, employing cold pressing or hot-forming after, make composite filled body not only cover around central layer and the connection box, and lower caldding layer on it has been connected in together by connecting the space, by filler opening with the composite filled body in the hollow steel pipe with reach the composite filled body that is connected on the space up and down and be linked as one, thereby constituted the advanced composite material (ACM) of a solid netted frame structure, improved the bond strength of product compositions greatly, made the bulk strength of product obtain basic assurance.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
Embodiment 1: as shown in Figures 1 and 2, composite brick machine supporting plate, comprise by central layer 1, supporting plate framework 4 and composite filled body 5 that connection box 2 and hasp 3 are formed, hasp 3 is fixed on the connection box 2, central layer 1 is embedded in the hasp 3, leave between connection box 2 and the central layer 1 and be connected space 6, composite filled body 5 is coated on central layer 1 and connection box about in the of 2, reach all around and connect in the space 6, a kind of framework of connection box 2 for being welded by hollow steel pipe, on hollow steel pipe, have filler opening 7, the material of composite filled body 5 is filled in hollow steel pipe inside by filler opening 7, central layer 1 is a wooden boards, bamboo lumber, glued board, particieboard, position plate, bamboo, wood or straw density board, the material of composite filled body 5 is the PP to recycle, thermoplasticity waste or used plastics such as PE are major ingredient, according to modifying plastics method commonly used, add corresponding coupling agent, surfactant, age resister, lubricant etc., inorganic matter or wood chip such as powder filler coal ash alone or in combination, strings such as stalk, the modified composite material that forms through fusion.
Embodiment 2: the manufacture method as embodiment 1 described composite brick machine supporting plate is: the making of a, supporting plate framework 4: the edge inboard that hasp 3 is fixed on connection box 2, central layer 1 is embedded in the hasp 3, between connection box 2 and central layer 1, leave and be connected space 6, on the hollow steel pipe of forming connection box 2, offer filler opening 7, then supporting plate framework 4 is placed in the mould; The preparation of b, composite filled body 5: broken reclaimed materials or particulate material and filler are placed in the special-purpose homogenizer, be equipped with material modifiedly, after high speed is mixing, melt extrude into bulk, be incubated standby through plastic extruder; The compression moulding of c, composite brick machine supporting plate: adopt cold-press process,, place above the supporting plate framework 4 in the mould, normal temperature compression moulding in hydraulic press, deburring after the demoulding directly with the composite filled body 5 of the bulk for preparing.
