Elastic material and low-noise electric-heating kettle

Abstract

The invention discloses an elastic material and a low-noise electric-heating kettle. The elastic material is obtained by reaction of a component A and a component B, wherein the component A comprisesthe following components in parts by weight: 35-40 parts of polyether polyol, 25-35 parts of polyester polyol, 1-5 parts of 1, 4-butanediol, 1-5 parts of MOCA, 0.1-1 part of catalyst, 1-2 parts of foam homogenizing agent, 1-2 parts of water and 0.1-1 part of pigment; the component B comprises the following components in parts by weight: 30-35 parts of MDI (Diphenyl Methane Diisocyanate) and 5-10 parts of TDI (Toluene Diisocynate), wherein the hydroxyl value of the polyether polyol is 50-300mgKOH / g, and the hydroxyl value of the polyester polyol is 50-300mgKOH / g. The elastic material provided by the embodiment of the invention has the beneficial effects that the compression stiffness is more than 3MPa / mm respectively and the permanent compression deformation is less than 5% respectively. Therefore, an elastic base made of the elastic material provided by the embodiment of the invention is soft and has the advantages of good buffering performance, good resilience, reduced permanent compression deformation, long service life and good damping and noise-reducing performances.

Description

technical field [0001] The invention relates to the technical field of electric kettle manufacturing, in particular to an elastic material and a low-noise electric kettle. Background technique [0002] Electric kettle refers to an electric water boiler used in hotel rooms for self-boiling water for guests. It generally has a split power base, automatic switch for boiling water, water level indication standards, power indicator lights, dry protection and other safety devices. General technical indicators It is about 950W, the water capacity is from 0.5 to 2 liters, and the voltage is 220-240V. Electric kettles are popular among consumers because of their fast and convenient boiling water. [0003] In the prior art, the electric kettle makes a huge noise during the working process, which brings great adverse effects to users, resulting in extremely poor user experience. Contents of the invention [0004] The technical problem to be solved by the present invention is how to...
