Example Embodiment

[0013] The present invention discloses a low-odor and low-VOC micro-foaming sealant strip, comprising the following mass parts of raw materials: 100 parts of EPDM raw rubber, 160-180 parts of carbon black, 40-60 parts of light calcium, paraffin wax 70-90 parts of oil, 6-8 parts of zinc oxide, 1-2 parts of stearic acid, 1-2 parts of surface active agent PEG-4000, 8-10 parts of moisture absorbent, 1.5-2 parts of sulfur powder Parts, accelerator TMTD is 0.5-1 part, accelerator NA-22 is 0.5-1 part, accelerator DM is 1-1.5 parts, accelerator ZDBC is 1.5-2 parts, and physical foaming agent is 0-3 parts. It also includes 0.3-0.5 parts of accelerator MBT and 0.3-0.5 parts of foaming agent OBSH. Preferably, the accelerator MBT is 0.3-0.4 parts, and the foaming agent OBSH is 0.4-0.5 parts.

[0014] Of course, the mass fraction range of some raw materials can also be appropriately reduced, that is, raw materials including the following mass parts: 100 parts of EPDM raw rubber, 170-180 part...

Abstract

The invention relates to the technical field of rubber producing and processing, in particular to a low-odor low-VOC micro-foaming sealing rubber strip. The low-odor low-VOC micro-foaming sealing rubber strip is prepared from, by mass, 100 parts of EPDM raw rubber, 160-180 parts of carbon black, 40-60 parts of light calcium, 70-90 parts of paraffin oil, 6-8 parts of zinc oxide, 1-2 parts of stearic acid, 1-2 parts of a surfactant PEG-4000, 8-10 parts of a moisture absorbent, 1.5-2 parts of sulphur powder, 0.5-1 part of an accelerant TMTD, 0.5-1 part of an accelerant NA-22, 1-1.5 parts of an accelerant DM, 1.5-2 parts of an accelerant ZDBC and 0-3 parts of a physical foaming agent. The low-odor low-VOC micro-foaming sealing rubber strip has the advantages that due to the fact that the physical foaming agent is added into solid rubber, holes are formed in the fracture surface, and volatilization of vulcanization residues in vulcanization is facilitated; by additionally using the paraffin oil, the volatilization quantity of the sealing strip itself is decreased, and therefore the purposes of lowering the weight of the sealing strip and improving the odor level are achieved; meanwhile, it can be guaranteed that the product has the excellent sealing property and the good handfeel in the using process, the product mass and product density are decreased, and the processing cost of manufacturers is lowered.

Description

technical field [0001] The invention relates to the technical field of rubber production and processing, in particular to a low-odor and low-VOC micro-foaming sealing strip. Background technique [0002] The rubber material of the first and second seals of the car door seals and the luggage compartment seal is currently mainly composed of foamed sponge seals produced by EPDM rubber and dense skeleton glue, installed on the car door sheet metal, on the door In the closed state, it is squeezed together with the door frame to play a sealing role. It mainly plays the role of door sealing, dustproof, shockproof and noise prevention. It is an indispensable part of the car door. There are one or two sealing strips and The production of the luggage compartment sealing strip adopts the sponge formula obtained by vulcanizing and foaming EPDM rubber with a chemical foaming agent and the dense skeleton rubber formula obtained by vulcanizing EPDM without adding a foaming agent. This kin...
