Technical Field
The invention belongs to the technical field of condoms, and particularly relates to a temperature-sensing reversible color-changing condom and a preparation method thereof.
Background
Condoms are widely used in human life, but lack innovation. Specifically, condoms on the market are all fixed in color, and are either the color of latex itself or the color of pigment which appears after the addition of pigment, which is very old. There is currently no condom which can be changed with temperature changes.
Disclosure of Invention
The invention aims to provide a novel temperature-sensing reversible color-changing condom and a preparation method thereof, which can increase the use interest of the condom, improve the use willingness of the condom and reduce accidental pregnancy.
The invention innovatively designs a novel temperature-sensing reversible color-changing condom, namely the color of the condom can change along with the change of temperature. The color change of the temperature-sensing reversible color-changing condom comprises the changes of hue, lightness and saturation, and the change processes can reflect the ambient temperature or the body surface temperature of a contacted human body to a certain extent, so that the experience pleasure of a user is increased while the freshness of consumers is provided.
The color of the condom of the invention can change within a certain critical temperature range, and the change can be the change of hue, lightness or saturation. The color change of the condom may be from colorless to colored, from colored to colorless, from one color to another, or multiple color changes at different temperature stages. The critical temperature range of the change is 0-80 ℃, preferably 30-40 ℃, and most preferably 35 ℃. The condom may also contain one or more pigments.
One method of implementing the condom of the invention is to include one or more temperature-sensitive reversible toner.
The raw materials for the condom according to the invention are preferably natural latex, synthetic latex, a mixture of natural latex and synthetic latex, and modified latexes of the above latexes.
The invention can be prepared by a preparation method comprising the following steps:
preparing temperature-sensitive reversible color liquid: adding one or more temperature-sensitive reversible toner(s) into water to prepare temperature-sensitive reversible toner(s) with the mass fraction of 5-20%;
preparing a pigment mother solution: adding common pigment powder into the prepared temperature-sensitive reversible color-changing liquid according to 0-10% of the mass fraction of the temperature-sensitive reversible color-changing liquid, and mixing and dispersing to prepare a pigment mother liquid;
latex prevulcanization and centrifugation treatment: sequentially putting the latex into a pre-vulcanizing tank and a centrifugal machine for processing to obtain pre-vulcanized and centrifugally processed latex;
preparing temperature-sensitive reversible color-changing latex: adding the prepared pigment mother solution according to 0.01-40% of the mass fraction of the latex subjected to prevulcanization and centrifugation treatment, and fully mixing and stirring uniformly to prepare the temperature-sensitive reversible color-changing latex;
preparing and drying an adhesive film: immersing the condom mold into the temperature-sensing reversible color latex, placing for a moment, then taking out, and then drying the mold to obtain a dried adhesive film.
Curling, demoulding and shaping: and curling, demolding and shaping the dried adhesive film to obtain the temperature-sensitive reversible color-changing condom.
Wherein, the steps of preparing the adhesive film and drying can be repeated for 1-5 times, so that the thickness of the dried adhesive film is 20-100 um.
Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments. It should be understood that the scope of the present invention is not limited to the following examples. Various substitutions and alterations according to the general knowledge and conventional practice in the art are intended to be included within the scope of the present invention without departing from the technical spirit of the present invention as described above.
Example 1
A temperature-sensing reversible color-changing condom is characterized in that the color of the temperature-sensing reversible color-changing condom is bluish purple at normal room temperature or at the temperature of 35 ℃ or below, the color is darker as the temperature is lower, and the color of the temperature-sensing reversible color-changing condom is gradually changed from bluish purple to pink when the temperature is raised to above 35 ℃. The preparation steps of the novel temperature-sensing reversible color-changing condom capable of changing from bluish purple to pink along with the temperature change are as follows:
1) preparing temperature-sensitive reversible color liquid: adding a blue temperature-sensitive reversible toner capable of decoloring at 35 ℃ into water to prepare a temperature-sensitive reversible color liquid with the mass fraction of 10%;
2) preparing a pigment mother solution: adding common fluorescent red pigment powder into the prepared temperature-sensitive reversible color-changing liquid according to 1% of the mass fraction of the temperature-sensitive reversible color-changing liquid, and mixing and dispersing to prepare a pigment mother liquid;
3) latex prevulcanization and centrifugation treatment: sequentially putting the latex into a pre-vulcanizing tank and a centrifugal machine for processing to obtain pre-vulcanized and centrifugally processed latex;
4) preparing temperature-sensitive reversible color-changing latex: adding the prepared pigment mother solution according to 0.5 percent of the mass of the latex subjected to pre-vulcanization and centrifugal treatment, fully mixing and uniformly stirring to prepare the temperature-sensitive reversible color-changing latex;
5) preparing and drying an adhesive film: immersing the condom mold into the temperature-sensing reversible color latex, placing for a moment, then taking out, and then drying the mold to obtain a dried adhesive film. Repeating the steps for 3 times, wherein the thickness of the dried adhesive film is 35 um.
6) Curling, demoulding and shaping: and curling, demolding and shaping the dried adhesive film to obtain the temperature-sensitive reversible color-changing condom.
Example 2
The temperature sensing reversible color-changing condom has a color of blue when the temperature is generally room temperature or below 30 ℃, the color of the temperature sensing reversible color-changing condom is darker when the temperature is lower, and the color of the temperature sensing reversible color-changing condom is gradually changed from blue to colorless when the temperature is raised to be above 30 ℃. The preparation steps of the novel temperature-sensing reversible color-changing condom capable of changing from blue to colorless with the temperature change are as follows:
1) preparing temperature-sensitive reversible color liquid: adding a blue temperature-sensitive reversible toner capable of decoloring at 30 ℃ into water to prepare a temperature-sensitive reversible color liquid with the mass fraction of 15%, and using the temperature-sensitive reversible color liquid as a pigment mother liquid;
2) latex prevulcanization and centrifugation treatment: sequentially putting the latex into a pre-vulcanizing tank and a centrifugal machine for processing to obtain pre-vulcanized and centrifugally processed latex;
