Sponge capable of changing colors according to ambient temperatures and production technology of sponge

Abstract

The invention discloses a sponge capable of changing colors according to ambient temperatures and a production technology of the sponge, which solve the technical problem that the conventional sponge cannot change colors according to the ambient temperatures. According to the technical scheme, homogeneous thermochromic powders are uniformly distributed inside a sponge body and are capable of changing colors under different temperature difference conditions. The production technology comprises the following steps of: in a technology of producing the sponge by a box foaming method, agitating raw materials for producing the sponge at a high speed, adding the thermochromic powders into the raw materials, and then agitating the mixture at a high speed until he thermochromic powders are uniformly distributed in the raw materials of the sponge; putting the raw materials, in which the thermochromic powders are uniformly distributed, of the sponge into a sponge forming box, and performing the procedures of chain propagation, forming, crosslinking and curing on the raw materials to obtain the formed sponge; and slitting the formed sponge according to actual sizes, wherein the thermochromic powders are ensured to be uniformly distributed on each slit surface of the sponge. The sponge has the beneficial effects that the technology is simple, the production cost is low, and the sponge is convenient to produce on the basis of not changing the production devices and the production technology.

Description

technical field [0001] The invention relates to a sponge capable of changing color according to ambient temperature and a production process thereof. Background technique [0002] With the change of sponge performance and the method of sponge production is simple and convenient, the application of full elastic (also known as space sponge) sponge is expanding, such as sponge mattresses, backrests, pillows, etc., the existing sponges do not change according to the ambient temperature The function of color is used for sponges that change with ambient temperature, such as sponges that are in direct contact with the human body. In order to show changes in human body temperature and ambient temperature, existing sponges cannot be realized. [0003] Due to the emergence of temperature-sensitive color-changing powder materials, sponges that can change color according to the ambient temperature have been realized in technology. Contents of the invention [0004] In order to solve ...
