Embodiment 1

[0025] A butadiene rubber sealing putty material of the present invention comprises the following components in parts by mass: 100 parts of butadiene rubber, 450-500 parts of softener, 35-40 parts of tackifier, and 3500-4000 parts of filler 20-30 parts of whitening agent, 1-1.5 parts of whitening agent; wherein, the butadiene rubber is cis-1,4-polybutadiene rubber; the softener is transparent paraffin oil or transparent naphthenic oil; the tackifier is polyisobutylene PB1300 or polyisobutylene PB2400; the filler is 400-800 mesh heavy calcium carbonate; the whitening agent is titanium dioxide; The agent is ultramarine blue; preferably, the ratio of the parts by mass of the whitening agent to the whitening agent is 20:1.

[0026] The formula used in the present invention is different from the prior art in that it creatively utilizes the property that butadiene rubber is prone to swelling when encountering mineral oil, and the butadiene rubber film is placed in transparent paraff...

Embodiment 2

[0035] A kind of butadiene rubber sealing putty material of the present embodiment 2 comprises each component of following mass fraction: 100 parts of butadiene rubber, 475 parts of softener transparent paraffin oil, 37.5 parts of tackifier polyisobutylene PB1300, fill 3750 parts of ground calcium carbonate, 25 parts of whitening agent titanium dioxide, and 1.25 parts of whitening agent ultramarine blue.

[0036] The trade mark of each component in the present embodiment 2 is identical with embodiment 1.

[0037] A kind of preparation method of butadiene rubber sealant cement material of present embodiment 2, its steps are:

[0038] (1) Foam rubber: Press the butadiene rubber into a film with a thickness of 1 to 2mm on an open mill, then place the butadiene rubber film in transparent paraffin oil twice its own weight, soak it for 24 hours, and it will be transparent at this time The paraffin oil has basically been imbibed into the butadiene rubber;

[0039] (2) Kneading: Put...

Embodiment 3

[0043] A kind of butadiene rubber sealing putty material of the present embodiment 3, it comprises each component of following mass fraction: 100 parts of butadiene rubber, 500 parts of softening agent transparent paraffin oils, 40 parts of tackifier polyisobutylene PB1300, 4000 parts of heavy calcium carbonate filler, 30 parts of whitening agent titanium dioxide, 1.5 parts of whitening agent ultramarine blue.

[0044] The trade mark of each component in the present embodiment 3 is identical with embodiment 1.

[0045] A kind of preparation method of butadiene rubber sealing cement material of present embodiment 3, its steps are:

[0046] (1) Foam rubber: Press the butadiene rubber into a film with a thickness of 1 to 2mm on an open mill, then place the butadiene rubber film in transparent paraffin oil twice its own weight, soak it for 24 hours, and it will be transparent at this time The paraffin oil has basically been absorbed into the butadiene rubber;

[0047] (2) Kneadi...

Abstract

Belonging to the technical field of rubber, the invention discloses a butadiene rubber sealing puddle material and a preparation method thereof. The butadiene rubber sealing puddle material comprises the following components by mass: 100 parts of butadiene rubber, 450-500 parts of a softener, 35-40 parts of a tackifier, 3500-4000 parts of filler, 20-30 parts of a brightener, and 1-1.5 parts of a whiteness improver. The method provided by the invention makes use of the characteristic that butadiene rubber swells easily after encountering mineral oil, places butadiene rubber in mineral oil for soaking to turn it into a semi-liquid state, eliminates the banburying process, also shortens the kneading time, and effectively lowers the manufacturing cost. The butadiene rubber sealing puddle material provided by the invention has the advantages of good yellow resistance, small shrinkage, low material cost, environmental protection, and no peculiar smell, and the processing method is energy saving and efficient.

Description

technical field [0001] The invention belongs to the technical field of rubber, and more specifically relates to a butadiene rubber sealing mastic material and a preparation method thereof. Background technique [0002] After the installation of household electrical appliances, it is often necessary to seal the reserved holes in the walls of the room. Due to the good sealing effect of rubber materials and the convenience of sealing and removal, rubber materials are often used in actual sealing. After retrieval, some prior art involves the preparation of rubber plugging materials. For example, the Chinese patent 201610277527.8 with the publication date of August 10, 2016 discloses a decorative cover for the reserved opening of an air conditioner containing sealing glue, wherein the sealing glue consists of 50 parts of polyisobutylene, 15 parts of castor oil, 60 parts of silicon micropowder, hydrogen It is prepared by uniformly mixing 30 parts of magnesium oxide, 30 parts of c...
