Embodiment Construction

[0014] A water-absorbing cooling particle, which is composed of the following weight percentages: the particles include the following components in weight percentages: 20% to 80% of polyacrylic acid, 80% to 20% of acrylamide and an additive oxyolefin; the weight of the additive oxidized olefin It is 2% to 5% of the total amount of polyacrylic acid and acrylamide.

[0015] A method for preparing water-absorbing cooling particles, comprising the following steps:

[0016] Step 1: put polyacrylic acid and acrylamide into the reaction vessel in turn, heat and stir;

[0017] Step 2: heat up and stir, the reaction temperature of the reaction vessel is raised to 80 degrees, add the additive oxyolefin, and continue to heat and stir;

[0018] Step 3: heating reaction, the reaction temperature of the reaction vessel is raised to 150-180 degrees to produce granular polymer;

[0019] Step 4: cooling and sieving, cooling and sieving the granular polymer produced in step 3, and screening o...

Abstract

The invention discloses water-absorption-type temperature lowering particles. The water-absorption-type temperature lowering particles are prepared from, by weight, 20%-80% of polyacrylic acid, 20%-80% of acrylamide and oxyalkylene additives, wherein the weight of the oxyalkylene additives accounts for 2%-5% of the total weight of the polyacrylic acid and the acrylamide. A preparation method of the water-absorption-type temperature lowering particles comprises the following steps of heating stirring, temperature rising stirring, temperature rising reacting and cooling screening. According to the prepared crystal polymers, water absorption is super high and can be more than 1000 times, the crystal polymers can automatically absorb water at room temperature, water cannot be overflowed from the crystal polymers at room temperature even if pressure is exerted, the retainability is super high, and a small quantity of the crystals are absorbed under certain pressure and cannot be broken; the heat conductivity coefficient is improved, heat is automatically absorbed and dissipated, and cool air is automatically released to generate the temperature lowering effect.

Description

technical field [0001] The invention relates to a water-absorbing cooling granule and a preparation method thereof, belonging to the technical field of chemistry. Background technique [0002] In the hot summer, the high temperature often makes people feel bored and unbearable. Indoors, turning on the air conditioner is often one of the most common ways people use to cool down. Affects the health of the human body; outdoors, the sun is scorching, and there is no cooling appliance to cool down. People generally use drinking water to cool down, but this can only play a temporary cooling effect, and cannot really cool down. Contents of the invention [0003] (1) Technical problems to be solved [0004] In order to solve the above problems, the present invention proposes a water-absorbing cooling particle and a preparation method thereof. The prepared large particle crystal polymer has a good cooling effect, a long duration of refrigeration, and can be reused. [0005] (2) T...
