Embodiment 1

[0030] see figure 1 It is a structural schematic diagram of the heat-sealable silicone rubber elastomer film, and the heat-sealable silicone rubber elastomer film 10 includes a silicone rubber film layer 11, a polysiloxane copolymer layer 12 and a polyurethane elastomer film substrate 13, and polysiloxane copolymerization The material layer is coated on the surface of the polyurethane elastomer film substrate, and the silicone rubber film layer is attached to the polysiloxane copolymer layer.

[0031] The polysiloxane copolymer layer 12 is a grafting agent, and the polysiloxane copolymer layer 12 is coated on the surface of the polyurethane elastomer film substrate 13 by roll coating or manually, and is exposed to the air at normal temperature or in a heated environment, and the solvent After volatilization, a layer of silicone film is formed, which is firmly bonded to the surface of the attached substrate, which facilitates the bonding of the silicone rubber film layer and im...

Embodiment 2

[0037] see image 3 It is a production equipment for heat-sealable silicone rubber elastomer film, including a substrate unwinding device 1, a calender 2, a feeding device 3, a segmented vulcanization tank 4 and a coiling device 5. The substrate unwinding device 1 , the calender 2 , the feeding device 3 , the segmented vulcanization tank 4 and the coiling equipment 5 are connected sequentially through a conveyor belt 6 .

[0038] Specifically, the substrate unwinding device 1 is used to place the pretreated polyurethane elastomer film substrate 13 on the conveyor belt 6, the calender in this embodiment is a 5-roll calender, and the segmented vulcanization tank includes 4 stages of vulcanization The temperature difference between each vulcanization tank 4 is controlled to be ±5°C. The coil equipment 5 includes a protective film roller 51 and a release paper roller 52. The protective film roller 51 is used to attach the protective film to the middle film. , The release paper cy...

Abstract

The invention discloses heat-sealable silicone rubber elastomer film, comprising a silicone rubber film layer, a polysiloxane copolymer layer and a polyester elastomer film base. The polysiloxane copolymer layer is applied to the surface of the polyester elastomer film base. The silicone rubber film layer is attached to the polysiloxane copolymer layer. The invention also discloses production equipment and preparation method of the heat-sealable silicone rubber elastomer film. The advantages of polyurethane elastomer and the advantages of organosilicon rubber are integrated herein; a vulcanized silicone rubber compound and the polysiloxane copolymer layer are applied to the polyester elastomer film base to form the heat-sealable organosilicon elastomer in organosilicon block copolymerization manner; the defects of single polymer film components in terms of performance are eliminated; a polymer alloy with complementary integrated properties is attained.

Description

technical field [0001] The invention relates to the technical field of heat-sealable films, in particular to a heat-sealable silicon rubber elastomer film and its production equipment and preparation method. Background technique [0002] At present, the heat-sealable films at home and abroad are mainly PVC plastics, and some are polymer elastic materials. The former is not resistant to aging, high temperature and poor flexibility due to its own defects. Moreover, harmful substances will be produced during its production and use, which will pollute the environment. The latter elastomer material film is superior to PVC plastic film in performance, energy saving and environmental protection, but the cost is high, the texture is hard, the ductility is poor, and it is easy to use for a long time. Cracks, yellowing and fading, and "wax breaking" phenomenon. As a silicone rubber film with superior environmental protection and excellent performance, because it is a single vulcanize...
