Problems solved by technology

However, because its structural strength is not high enough, and it is almost impossible to bond, there are common problems in connection and installation with structural materials such as steel and reinforced concrete in engineering applications.
The perforated mechanical installation often destroys the overall wear resistance of the liner. At the same time, because the metal fasteners have low wear resistance and are easy to corrode, the reliability of the liner is reduced; the metal bolts used for back drilling When the fastener is directly fastened, due to its low material strength, it is easy to deform and loosen, so that it cannot provide reliable installation performance, resulting in falling off; the connection with the slot structure is relatively reliable, but the amount of machining is large, the consumption of materials is high, and the cost is high
The defect of connecting with other materials hinders the expansion of the application field of ultra-high molecular weight polyethylene materials

Embodiment 1

[0034] Such as figure 1 As shown, the embedded nut type ultra-high molecular weight polyethylene board includes an ultra-high molecular weight polyethylene liner 1 , a stainless steel gasket 2 embedded therein, an embedded nut 3 , fixing bolts 4 and concrete 5 .

[0035] The ultra-high molecular weight polyethylene bottom plate 8 is made of ultra-high molecular weight polyethylene raw materials with a molecular weight of 4 million and a particle size of 80 mesh.

[0036] The embedded nut is a hexagonal stainless steel nut 3 whose model is M12.

[0037] The size of the stainless steel gasket 2 is 40×40×3mm.

[0038] The model of the fixing bolt 4 is M12×80mm

[0039] The manufacturing method of the above embedded nut type ultra-high molecular weight polyethylene plate comprises the following steps:

[0040] 1) Prepare the stainless steel hex nut 3, the model is M12, the width across the sides of the nut 3 is 21.9mm, and the height of the nut 3 is 10mm;

[0041] 2) Process a...

Embodiment 2

[0050]Basically consistent with Example 1, the difference is that the manufactured embedded nut type ultra-high molecular weight polyethylene plate is installed on the steel structure, and the used embedded hexagonal nut 3, model: M16, size is: nut height H= 13mm, width D of the nut across sides = 27.7mm, and the thickness H of the manufactured nut-embedded ultra-high molecular weight polyethylene plate 8 is 13mm. The steps are as follows: install M16×80 bolts 4 on the produced embedded nut type ultra-high molecular weight polyethylene plate 8, and fasten them; One side of the bolt 4 faces the steel structure, the bolt 4 is screwed into the steel structure, and the surface of the liner 1 is tapped to make it fit the surface of the steel structure. The connection between the ultra-high molecular weight polyethylene liner 1 and the steel structure is realized, and no metal parts are exposed on the surface of the liner.

Abstract

The invention puts forward a method for preparing an ultrahigh molecular weight polyethylene plates embedded with a nut. The method is characterized in that the nut and a washer are fixed by use of a bolt through a central hole; after the nut is brazed with the washer along the outer edge of the nut, the nut is arranged on a prefabricated ultrahigh molecular weight polyethylene base plate; and the base plate is put into a hot-pressing molding die, added with ultrahigh molecular weight polyethylene powder, thermally insulated for 1 hour under the pressure between 15 and 30 MPa at a temperature of between 185 and 200 DEG C, and then is naturally cooled. After the plate is provided with the bolt, the plate can be fixed on a mechanical device, a concrete structure and other parts in need of wear-resistant protection, and is reliable in the bonding strength to a matrix.

Description

technical field [0001] The invention relates to a preparation method of an ultra-high molecular weight polyethylene material wear-resistant lining board, in particular to a preparation method of an embedded nut type ultra-high molecular weight polyethylene board. Background technique [0002] Ultra-high molecular weight polyethylene is a new type of engineering plastic with excellent performance, and its molecular weight is generally above 1.5 million. It has excellent wear resistance, especially its anti-sediment erosion and wear performance is higher than steel; its impact strength ranks first among all kinds of plastics; it has a very low coefficient of friction, extremely small water absorption and Excellent corrosion resistance. Based on these advantages, UHMWPE materials are widely used as wear-resistant, impact-resistant, corrosion-resistant or low-friction liners and pads in mining, textile, machinery, chemical and other fields, for example, as silo linings, Cargo ...
