Problems solved by technology

[0008] The use temperature of these materials is above room temperature, and when the use temperature is lower than 0°C, the deformation ability of the material drops sharply, or even loses the deformation ability, which limits its application in low temperature conditions.

Embodiment 1

[0026] The composition of a wide temperature range easily deformable non-rebound rubber material is: 1 part of 80 mesh heavy calcium carbonate, 100 parts of 80 mesh talc powder, 99 parts of 100 mesh talcum powder, 150 parts of 80 mesh reduced iron powder, 201 parts of methyl 60 parts of silicone oil, 30 parts of 101-1 dimethyl silicone rubber, 6 parts of chrome green, and 2 parts of cerium oxide.

[0027] Prepared by vacuum kneading process: Weigh each component in proportion, pre-mix powdery materials, put all the materials into a vacuum kneader and knead them, and knead them at room temperature until all components are evenly kneaded together to obtain the present invention. The involved green wide temperature range easily deformable non-rebound rubber material has a density of 2.62g / cm 3 , The amount of deformation is 55% at -30°C, and the amount of deformation is 124% at 45°C.

Embodiment 2

[0029] The components of a wide temperature range easily deformable non-rebound rubber material are: 15 parts of 100 mesh heavy calcium carbonate, 185 parts of 100 mesh talcum powder, 80 parts of 100 mesh reduced iron powder, 50 parts of 200 mesh stainless steel powder, 210 B 55 parts of base silicone oil, 35 parts of 101-2 dimethyl silicone rubber, 5.5 parts of chrome yellow, and 1.8 parts of cerium oxide.

[0030] The mixing process of the open mill includes the following steps: Weigh the components in proportion, pre-mix the powdery materials, then add the softener to the mixed materials, turn on the open mill, adjust to a suitable roller distance, put in rubber, and make It holds the roller, and gradually adds the mixed powdery material with softener until all of it is added, and then the material is thinly passed 10 to 20 times, and the material is unloaded and packaged. Obtain the yellow wide temperature range easily deformable non-elastic rubber material related to the ...

Abstract

The invention belongs to the technical field of material. With the adoption of the general rubber processing technology, a wide temperature range deformable rubber material with no springback is prepared by taking silicone rubber as a matrix, a mixture of calcium carbonate and powdered steatile as a main filling material, a nonvolatile liquid resin as a softener, a high-density powder as a density regulator, in combination with auxiliary agents such as an antioxidant. The rubber provided by the invention has little deformation resistance, strong deformation capability with no springback, nonstick and unshrinking properties and good storage stability, is suitable for a wide temperature range, can still maintain good deformation capability at the temperature of minus 30 DEG C; in addition, it is environmentally friendly and nontoxic, and can be recycled and reused.

Description

technical field [0001] The invention belongs to the field of material technology, and relates to rubber material technology, in particular to silicon rubber material technology. Background technique [0002] The easily deformable non-rebound rubber material is a rubber material that is soft in texture and can produce obvious deformation without rebound under the action of a very small external force. Its properties at room temperature are similar to plasticine and plasticine. [0003] Materials such as plasticine and plasticine are mixed with various oils, rubber materials and some powder fillers. [0004] Chinese patents CN 1352215A, CN1352217A disclose a kind of preparation method of supernormal temperature and normal temperature plasticine respectively, the preparation method that both are used all is to add powder filler after beeswax, microcrystalline wax, white vaseline, rosin are melted, after stirring evenly, cooling is finished. Yes, the material has a high densit...
