Faucet filled with anti-impact high-dense elastomer material and preparation method of faucet

Abstract

The invention relates to a faucet, in particular to the faucet filled with an anti-impact high-dense elastomer material and a preparation method of the faucet. The faucet comprises an acrylonitrile butadiene styrene (ABS) plastic shell and mating parts, wherein the mating parts comprise a valve core, a handle, a water outlet net, a seal ring, a fastening screw and the like. The method comprises the following steps of: combining and connecting water channels of the faucet according to a waterway requirement of the faucet; putting the water channels into a mould of a shell of the faucet and fixing the water channels; fusing a high-dense elastomer which is mixed with an inorganic filling material by an extruder, an injection moulding machine, a kneading machine and an open mill, and filling the high-dense elastomer into the mould of the shell of the faucet; cooling the high-dense elastomer in the mould until the high-dense elastomer is formed, taking the high-dense elastomer out of the mould, and carrying out injection moulding on the high-dense elastomer to form a plastic shell of the faucet; and carrying out surface treatment on the shell, installing the filled faucet into the plastic shell of the faucet, and assembling the prepared faucet mating parts which are produced by the conventional process and comprise the valve core, the handle, the water outlet net, the seal ring, the fastening screw and the like into the faucet filled with the anti-impact high-dense elastomer material according to the conventional assembling mode.

Description

technical field [0001] The invention relates to a faucet, in particular to a faucet filled with an impact-resistant large-density elastomer material and a preparation method thereof. Background technique [0002] Most of the plastic faucets on the existing market use acrylonitrile-styrene-butadiene copolymer (ABS) plastic as the shell, and carry out surface treatment (electroplating, vacuum coating, etc.) to present a high-gloss metal appearance, while the internal water channel The skeleton is injection-molded with resins such as polyoxymethylene (POM) or polyphenylene sulfide (PPS) or polyphenylene oxide (PPO). The disadvantage of this kind of plastic faucet is that the weight is not enough, and the burst pressure resistance of the water channel is not strong. [0003] At present, there are various faucets on the market, and there are roughly two kinds of mixed plastic faucets that can enter hot and cold water. ZL200710070171.1); the other is mainly composed of upper and...

Problems solved by technology

There are many steps to make the above-mentioned plastic faucet, which is cumbersome, time-consuming and labor-intensive, and the production cost is relatively high; in addition, the water inlet and outlet channels of the second type of faucet above are only composed of simple grooves, and the other parts of the upper and lower body are entities. More, the upper and lower bodies are prone to deformation during injection molding, and it is troublesome to accurately match the grooves of the upper and lower bodies, and the joint surface of the upper and lower bodies will expand with heat and contract with cold water, causing gaps to appear on the joint surface. Water strings or leaks are likely to occur between the hot water channels, which will affect the use of the faucet
