Problems solved by technology

In the existing door sealing strips, the coating materials for the installation part mainly include dense rubber and microporous rubber, etc. The product density of the coating rubber produced by using the compact rubber formula is 1.25g / cm 3 Left and right, its product density is relatively high, and the amount of glue used is large, which is not conducive to the realization of lightweight design
The product density of the coated rubber produced by the microporous rubber formula is also 1.15g / cm 3 It is difficult to continue to reduce the product density of the coated rubber with this formula, and at the same time, it is also prone to quality problems such as bulges in the production process

Abstract

The invention provides a sealing strip cladding sizing material and a preparation method thereof as well as a car door sealing strip and a preparation method thereof. The sealing strip cladding sizingmaterial of the invention is prepared from the following components: EPDM (Ethylene-Propylene-Diene Monomer) 3092M, EPDM 4045M, EPDM PX-049, zinc oxide, stearic acid, PEG-4000, a dispersing agent, tackifying resin, paraffin oil R-2291, carbon black N550, sulfur S-80, a moisture absorbent GR, an accelerant M-75, an accelerant DM-75, an accelerant TRA-70, an accelerant TMTD-75, an accelerant BZ-75,an accelerant ETU-80, and a microsphere foaming agent EWE-60GE. The sealing strip cladding sizing material of the invention can implement the light-weight design of a sealing strip product, also hasrelatively good physical properties such as processability and surface quality, and can improve the quality of a sealing strip utilizing the sealing strip cladding sizing material.

Description

technical field [0001] The invention relates to the technical field of sealing strip preparation, in particular to a sealing strip coating compound used for preparing the sealing strip, and also relates to a preparation method of the sealing strip coating compound. At the same time, the invention also relates to a door sealing strip made of the sealing strip coating compound, and a method for preparing the door sealing strip. Background technique [0002] The car door seal strip mainly plays the role of sealing, dustproof, waterproof and decoration, and it is installed on the sheet metal around the car door. When the car door is closed, the sealing effect is realized by the bonding between the sealing strip and the door frame, so as to prevent external wind, rain, dust and other harmful substances from invading the car, and reduce the risk of damage to the doors and windows when the car is running. Generates vibrations to maintain a sense of cleanliness and comfort and refi...
