A kind of environmental protection sealing strip

Abstract

The invention belongs to the technical field of sealing fittings, and is specifically an environmental protection sealing strip; it includes a main body and a fixing groove; the upper and lower ends of the main body are paired with two fixing grooves; A metal shrapnel is symmetrically arranged on the side; a communicating through groove is arranged at intervals between the two fixing grooves; a sliding rod is slidably connected in the through groove; two elastic fixing blocks are symmetrically fixed at both ends of the sliding rod; The sides of the two fixing blocks close to the bottom of the fixing groove are arc-shaped, and match with the bottom of the fixing groove; there are water-absorbing balls slidingly connected in the storage tank; the water-absorbing balls can absorb water mist and expand; The invention achieves a better sealing effect through the slow reaction and heat release of the water-absorbing balls installed inside and the lithium oxide powder, which enhances the sealing of doors and windows, and reduces the impact of poor sealing on the work of people in the car.

Description

technical field [0001] The invention belongs to the technical field of sealing fittings, in particular to an environment-friendly sealing rubber strip. Background technique [0002] There are three kinds of rubber materials for automobile sealing strips: compact rubber, sponge rubber and hard rubber. The hardness of hard rubber can reach Shore A95. The rubber of the sealing strip is mostly made of ethylene-propylene-diene monomer (EPDM) that is resistant to aging, low temperature, water vapor, and chemical corrosion, especially ozone aging. EPDM can be compounded with steel belt, steel wire braided belt, TPE, flannelette, flocking, PU coating, silicone coating, etc., to ensure the waterproof, dustproof, sound insulation, heat insulation, vibration reduction and anti Grinding and decorative effect. In general, EPDM sealing strips can be used stably for more than ten years. Chloroprene rubber (CR) with good ozone resistance and good aging resistance can also be selected. ...

Problems solved by technology

[0003] However, in the actual use process, the doors and windows of the vehicle will be sealed with sealing strips, but the transport vehicles that often enter the cold storage rush to and from the cold storage in a high outdoor temperature environment, which will cause a large amount of water mist to adhere to the doors and windows and fall. Water droplets, due to the large temperature difference will cause a certain amount of heat expansion and contraction of the sealant strip, so that part of the water droplets will slowly flow into the fixed groove of the sealant strip, so that it remains at the bottom and is difficult to remove. If the vehicle enters again, the bottom remains The water droplets may directly condense into ice in the low temperature environment, thereby squeezing the glass installed in the fixed groove, and at the same time, the sealing performance of the doors and windows will be deteriorated, which will greatly affect the work of the personnel in the car; accordingly, the present invention proposes a Environmental protection strip
