Abstract
The utility model discloses a wear-resisting lining board, which comprises a ceramic disc, polyurethane rubber and a natural rubber sheet, wherein the polyurethane rubber is poured between the ceramic disc and the natural rubber sheet to cause the ceramic disc and the natural rubber sheet to be cemented together, and the cementing performance is enhanced through the vulcanization of the rubber. By adopting the wear-resisting lining board, the weight of the lining board is greatly reduced, the cohesive force among the composite layers of the lining board is enhanced, and the smoothness of the lining board is ensured. The wear-resisting ceramic disc is used as a working surface, thus the high wear resistance of the ceramics is fully exerted, and the fatal weakness of the ceramics, namely, the brittleness problem is improved through the middle rubber buffering layer. Simultaneously, a rubber layer is arranged at the back of the wear-resisting lining board, and is provided with extremely strong stretching and distorting performances, and when the rubber layer is glued with the base course, the restriction of the smoothness of the base course is greatly reduced, thus the wear-resisting lining board can be well glued with the base course. Strong impacting resistance, light weight, good wear resistance and high cohesive force of the wear-resisting lining board are achieved, the service life is long, and the wear-resisting lining board is provided with the performances of easy installation and maintenance.
Description
Technical field
The utility model relates to abrasion-proof backing block, relates in particular to a kind of abrasion-proof backing block that is used for mass transport pipeline and hopper internal surface.
Background technique
In the prior art, be used to carry the pipeline of materials such as particle and powder and the wearing plate of hopper internal surface generally to constitute by general steel plate, glass cermaic plate.Because impact resistance is poor, the weight of glass cermaic plate is big, the factors such as bonding force difference of the adhesive material of lining cutting glass cermaic plate make its working life short; In recent years as the Cast Steel of wearing plate have equally that weight is big, installation and difficulty of processing greatly, shortcoming such as easy-maintaining not.And plain carbon steel plate bonded ceramics face exists not shock resistance, easy shortcoming such as come off as wearing plate.Ceramic-rubber steel plate composite abrasion-proof inner plate has appearred in addition recently, main way is that the three is synthetic by viscose glue, perhaps rubber and steel plate, rubber and ceramic plate are bondd respectively, perhaps with steel plate as base plate, between steel plate and ceramic plate, cross hot vulcanization and bond together by rubber.But these bondings are owing to be subjected to the restriction of traditional adhesive, and adhesion strength is subjected to very big restriction.And liner plate adopts steel plate material for the material hopper of conveying belt transportation, itself can cause a big potential safety hazard of seriously tearing to belt exactly, and therefore, the use in this class hopper is subject to significant restrictions.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of impact resistance is strong, light weight, wear resistance is good, cohesive force is high, long service life, is easy to install and keep in repair the abrasion-proof backing block of environmental protection simultaneously.
For solving the problems of the technologies described above, the utility model abrasion-proof backing block comprises ceramic plate, urethane rubber and natural rubber sheet, and described urethane rubber is cast between ceramic plate and natural rubber sheet so that they bond together.
For strengthening bonding force,, make ceramic plate and natural rubber sheet strong bond by the vulcanization of rubber.
Because the technique scheme that adopted of the present utility model, being about to urethane rubber pours between ceramic plate and natural rubber sheet also by sulfuration urethane rubber reinforcement bonding force, greatly reduce the weight of liner plate thus, improve the cohesive force between each composite bed of liner plate, and guaranteed the flatness of liner plate.Use wear-resisting ceramic plate as working surface, give full play to the high wear resistance of pottery, and the cushion rubber layer of the fatal weakness fragility problem of pottery by the centre is improved.The abrasion-proof backing block back side is rubber layer simultaneously, has extremely strong stretching and deformability, when boning with basic unit, reduced greatly by the restriction of Base Smoothness, and abrasion-proof backing block and basic unit can be bondd well.Realized that this abrasion-proof backing block impact resistance is strong, light weight, wear resistance is good, cohesive force is high, long service life, is easy to the performance of installing and keeping in repair.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of abrasion-proof backing block of the present utility model.
Embodiment
As shown in the figure, the utility model abrasion-proof backing block comprises ceramic plate 1, urethane rubber 2 and natural rubber sheet 3, and described urethane rubber 2 is cast in ceramic plate 1 and 3 of natural rubber sheets so that they bond together.
For strengthening bonding force,, make ceramic plate 1 and natural rubber sheet 3 strong bond by vulcanizing described urethane rubber 2 and natural rubber sheet 3.
Deficiency at original abrasion-proof backing block: in the bonding that has steel plate as backing board or employing viscose glue technology realization wear-resistant ceramic sheet and yielding rubber layer, the shortcoming that its cohesive force is relatively poor relatively.By realize the bonding of wear-resistant ceramic sheet and rubber plate with existing adhesive, adopted hot vulcanization to compare with adopting the wear-resistant ceramic sheet with rubber, the adhesion strength that found through experiments the latter obviously will be higher than the former, but adopted the hot vulcanization bonding, original technology must have steel plate as supporting plate, because the sheet bending distortion that ceramic plate and rubber are crossed after the hot vulcanization is serious unusually, and problem on deformation has just thoroughly solved after using the steel supporting plate.Never to use the steel supporting plate but can guarantee the flatness of sheet material and alleviate the weight of sheet material that this abrasion-proof backing block is realized plate surface evenness problem by the hardness that increases urethane rubber and natural rubber in order to separate; The utility model is put into fixed mould with wear-resistant ceramic sheet 1, pours into urethane rubber 2 then, is covered with natural rubber sheet 3, through heating, pressurization, the demoulding make abrasion-proof backing block.
Claims (2)
1, a kind of abrasion-proof backing block comprises ceramic plate and natural rubber sheet, it is characterized in that: also comprise urethane rubber, pour into described urethane rubber so that they bond together between described ceramic plate and natural rubber sheet.
2, abrasion-proof backing block according to claim 1 is characterized in that: the cast of described urethane rubber, and the flatness of assurance liner plate makes described ceramic plate and urethane rubber strong bond; The sulfurized natural rubber sheet makes described urethane rubber and natural rubber sheet strong bond.
