Problems solved by technology

[0003] At present, the technology and products of domestic rubber flaps are relatively lacking. High-end toilets basically rely on expensive imported products. Medium and low-end toilets basically use ordinary rubber flaps or soft PVC flaps + silicone gaskets. The products of these two materials are increasingly unable to meet the needs of the market, mainly because of the high price, short service life, and relatively high cost.
Products with strict requirements on performance and service life basically rely on foreign imports, and the price is quite expensive

Embodiment 1

[0045] The rubber clapper cover material of the present embodiment comprises the following components in parts by weight:

[0046]

[0047] The above-mentioned rubber substrate adopts EPDM rubber; the active agent adopts zinc oxide and stearic acid; the tackifying resin adopts terpene resin; the softener adopts paraffin oil; the reinforcing agent adopts carbon black and white carbon black; 500-5000 mesh talcum powder is used as filler; dithiocarbamate is used as accelerator; sulfur is used as vulcanizing agent.

[0048] The formula of the rubber clapper cover of this embodiment (named Y3) is prepared by using the above-mentioned rubber clapper cover material through the following steps:

[0049] Step 1. Internal mixer mixing

[0050] After raising the temperature of the internal mixer to 50°C, put in EPDM, stir for 10 minutes to make the rubber base material soften and uniform, add the active agent, stir for 5 minutes to make the active agent disperse evenly in the rubber ...

Embodiment 2

[0071] The rubber clapper cover material of the present embodiment comprises the following components in parts by weight:

Abstract

The invention discloses a rubber racket cover material and a preparation method of the rubber racket cover. The rubber racket cover material comprises the following components in parts by weight: 40-50 parts of rubber base material, 2-10 parts of active agent, 0-5 parts of adhesive resin, 5-15 parts of softener, 20-35 parts of reinforcing agent, 10-30 parts of filler, 1-5 parts of accelerator and 0.2-1.2 parts of vulcanizing agent. The rubber clapper cover of the present invention has the advantages of good sealing, corrosion resistance, aging resistance, chlorine ammonia resistance and good water-saving performance, and after the specific gravity of each component in the material is optimized, it will not affect the falling speed of the clapper cover. It will not affect the drainage of the whole toilet. The rubber clapper cover of the present invention is easy to install, can be disassembled and replaced at will, has good permanent leak-proof sealing effect, and is convenient for color matching, and is suitable for toilet water tank accessories to achieve water-saving and leak-proof effects.

Description

technical field [0001] The invention relates to a rubber material for a bathroom system, in particular to a rubber clap cover material and a preparation method of the rubber clap cover. Background technique [0002] The rubber clap cover is a key accessory used in the toilet tank. It is easy to install, can be disassembled and replaced at will, has a good permanent leak-proof sealing effect, and is easy to color. It is suitable for toilet tank accessories to save water and prevent leakage. The required characteristics of the product are: in the specified special test solution, under the constant temperature condition of 50-80°C, the rubber product is soaked in the solution, the test time is ≥5 weeks, and the volume change rate of the rubber is ≤25% as the basic qualified condition . [0003] At present, the technology and products of domestic rubber flaps are relatively lacking. High-end toilets basically rely on expensive imported products. Medium and low-end toilets basic...
