Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a nano-reinforced glass fiber composite mold cleaning material, which solves the problem that the mold cleaning agent in the prior art is irritating when cleaning the mold, and it will become sticky after preheating. Copper frames of different sizes must also be used in combination; and the mold-cleaning film is fragile during production and is not easy to release the mold.

Embodiment 1

[0020] First, 100 parts of unvulcanized rubber is masticated for 2-5 minutes in an internal mixer, an open mixer, and an extruder, and the reinforcing filler is added in turn, that is, 15 parts of short glass fiber reinforcement material, 40 parts of silica, 7 parts Cleaning agent, 0.5 part of processing aid and 1 part of coloring agent, finally add 0.3 part of vulcanizing agent and 1.5 part of vulcanization accelerator, control the temperature at 80-110 ℃ and knead for 15-30 minutes to obtain a uniform rubber compound , and then use a molding machine to form a sheet or strip. The initial raw material for mold washing is kneaded in a closed kneader, pressed into a sheet material, and finally cut into a strip product.

Embodiment 2

[0022] First, 100 parts of unvulcanized rubber is masticated for 2-5 minutes in an internal mixer, an open mixer, and an extruder, and the reinforcing filler is added in turn, that is, 23 parts of short glass fiber reinforcement materials, 53 parts of silica, 18 parts Cleaning agent, 2.8 parts of processing aid and 6 parts of coloring agent, finally add 4.7 parts of vulcanizing agent and 3.3 parts of vulcanization accelerator, control the temperature at 80-110°C and knead for 15-30 minutes to obtain a uniform rubber compound , and then use a forming machine to form a sheet or strip. The initial raw material for mold washing is kneaded in a closed kneader, pressed into a sheet material, and finally cut into a strip product.

Embodiment 3

[0024] First, 100 parts of unvulcanized rubber is masticated for 2-5 minutes in an internal mixer, an open mixer, and an extruder, and the reinforcing filler is added in turn, that is, 30 parts of short glass fiber reinforcement material, 65 parts of silica, 28 parts Cleaning agent, 5 parts of processing aid and 10 parts of coloring agent, finally add 9 parts of vulcanizing agent and 5 parts of vulcanization accelerator, control the temperature at 80-110°C and knead for 15-30 minutes to obtain a uniform rubber compound , and then use a forming machine to form a sheet or strip. The initial raw material for mold washing is kneaded in a closed kneader, pressed into a sheet material, and finally cut into a strip product.

[0025] Finally, on the client side, the operator puts the adhesive tape on the mold, closes the mold and presses it, heats it to 160-190°C, keeps it for 4-8 minutes, then opens the mold, removes the film, and the dirt on the mold is stuck on film, while the mold...

Abstract

The invention discloses a nano-reinforced glass fiber composite mold cleaning material, which is used for solving the problems that an existing mold cleaning agent is irritant when used for cleaning amold, becomes sticky after being preheated, and must be matched with copper frames with different sizes in the using process, and a mold cleaning rubber sheet is fragile in production and is not easyto demold. The nano-reinforced glass fiber composite mold cleaning material is prepared from the following components in parts by mass: 100 parts of unvulcanized rubber, 15-30 parts of a short glassfiber reinforced material, 40-65 parts of silicon dioxide, 7-28 parts of a cleaning agent, 1-10 parts of a coloring agent, 0.5-5 part of a processing aid, 1.5-5 parts of a vulcanization accelerator and 0.3-9 part of a vulcanizing agent. According to the invention, the nano-reinforced glass fiber composite mold cleaning material does not contain a melamine component, has small irritation to operators in the mold cleaning process, has strong mold cleaning ability, reduces the mold cleaning cost, improves the production efficiency, and is convenient for the operators to operate, and the rubber sheet is complete and not easy to break.

Description

technical field [0001] The invention relates to the field of nanomaterials, in particular to a nanometer-reinforced glass fiber composite material with mold cleaning function. Background technique [0002] During the production of injection molds, some plastic sealing compound will inevitably remain on the mold. After accumulating to a certain extent, it will cause the mold to be dirty and affect the appearance of the product. In severe cases, it will cause the vent hole of the mold to be blocked, resulting in internal defects in the product. Problems such as cavities, and the dirt of injection molds in the electronics industry may even lead to failure of product reliability, thereby affecting the function of the entire product. [0003] However, the traditional mold cleaning method is to disassemble the mold and use physical or chemical methods to clean the mold, but this method is very time-consuming and labor-intensive in the process of disassembling the mold. For precisi...
