Embodiment 1

[0012] (1) Mix EPDM rubber and 66 parts of compounding agent on an open mill with a roll temperature of 50-60 °C and a roll distance of 1-2 mm for 20-25 minutes to make the first mixed rubber to be prepared The compounding agent is composed of white carbon black, zinc oxide, stearic acid, vulcanizing agent, vulcanization accelerator and anti-aging agent D in a mass ratio of 30:5:2:3:25:1. (2) Mix EPDM rubber and 73 compounding agent on an open mill with a roll temperature of 50-60 °C and a roll distance of 1-2 mm for 20-25 minutes to make the second mixed rubber for use , wherein the compounding agent is composed of white carbon black, zinc oxide, stearic acid, vulcanizing agent, vulcanization accelerator, and anti-aging agent D in a mass ratio of 30:5:2:5:30:1. (3) Inject the first mixed rubber into the cavity of the single mold through a runner of the injection press, and mold it under the conditions of 170°C and 10MPa to obtain the product.

Embodiment 2

[0013] The preparation method of the mixed rubber of embodiment 2 ~ embodiment 5 is the same as that of embodiment 1, but the molding methods are as follows:

Embodiment 2

[0015] The first mixed rubber is injected into multiple mold cavities through a runner of the injection press, and molded under the conditions of 170°C and 10MPa to obtain a product.

Abstract

The invention discloses a method for preparing a rubber spectacle frame, wherein the preparation method comprises: (1) putting EPDM rubber and two compounding agents on a roll temperature of 50-60°C and a roll distance of 1-2 mm; Mix on the open mill for 20-25 minutes, and prepare two kinds of EPDM rubber mixes with different ratios for use; (2) Inject the two kinds of mixes into the membrane through the two flow channels of the injection press machine The cavity is molded under the conditions of 170°C and 10MPa to obtain the product. The invention adopts an injection molding method, has a simple preparation process, can greatly improve the qualified rate of products, and reduces waste of raw materials, and the rubber spectacle frame is beautiful and fashionable, and has excellent wear resistance, corrosion resistance, weather resistance and toughness.

Description

technical field [0001] The invention relates to the field of spectacle frames, in particular to a method for preparing a rubber spectacle frame. Background technique [0002] Rubber spectacle frames require that they must have excellent hardness, wear resistance, corrosion resistance, weather resistance, and light weight. There are three main types of spectacle frames: metal spectacle frames, plastic spectacle frames, and natural material spectacle frames. Metal spectacle frames are divided into copper alloys, nickel alloys and precious metals. Copper alloys have poor corrosion resistance and are easy to rust; nickel alloys have better durability and corrosion resistance, and are not easy to rust, and their mechanical properties are also better than copper alloys, but because of their higher density, they are heavier; precious metals, such as gold and platinum , gold-packed their cost is very high and not suitable for the masses. The plastic spectacle frame is light in we...
