Embodiment Construction

[0014] see figure 1 , figure 1 It is a schematic diagram of the cross-section structure of the sawtooth rubber sealing strip for five-wrapped ship hatch covers of the present invention. Depend on figure 1 It can be seen that the sawtooth rubber sealing strip for five-bread skin ship hatch covers of the present invention comprises a sponge core 1, and the sponge core 1 is a straight strip whose upper part cross-section is square and the lower part cross-section is an inverted trapezoid. The outer edge is covered with rubber skin 2 except the top surface, and the material of rubber skin 2 is EPDM rubber, and the joint surface of rubber skin 2 and sponge core 1 is bonded with glue 3 .

[0015] The bottom end surface and the left and right side surfaces of the rubber skin 2 are arranged as serrated surfaces 4 .

Abstract

The invention relates to a five-side wrapped boat cabin opening cover sawtooth rubber sealing strip, which is mainly used for boat cargo cabin cover sealing. The sealing strip comprises a sponge core (1), wherein the cross section of the upper part of the sponge core (1) is in a square shape, the cross section of the lower part of the sponge core (1) is in a reverse trapezoidal flat and straight strip, the outer edges, except the top surface, of the sponge core (1) are respectively coated with rubber (2), the rubber (2) is made of ethylene-propylene-diene monomers, the joint surfaces of the rubber (2) and the sponge core (1) are bonded through glue slurry (3), and the bottom end surface and the left and right side surfaces of the rubber (2) are made into sawtooth surfaces (4). The five-side wrapped boat cabin opening cover sawtooth rubber sealing strip has the beneficial effects that the outer edge of the sponge core is coated with the rubber, on the premise of maintaining the original elasticity of the sponge core, the ageing resistance performance is good, the compression deformation quantity is small, and the service life is long. The slippage cannot be generated between matching joint surfaces with other parts.

Description

(1) Technical field [0001] The invention relates to a rubber sealing strip. It is mainly used for the sealing of ship cargo hatch covers. It belongs to the technical field of rubber seals. (2) Background technology [0002] Before the present invention was made, the sealing strips currently used for the sealing of ship cargo hatch covers were all formed by a single foam. Although the sponge sealing strip has good elasticity and light weight, it is easy to age, compress and deform, and has a short service life. (3) Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, provide a kind of anti-aging, the compression deformation amount is little the sawtooth rubber sealing strip of the hatch cover of five bread leather ships. [0004] The object of the present invention is achieved like this: a kind of five bread-skin ship hatch covers sawtooth rubber sealing strip, comprises sponge core, and sponge core is the flat...
