Problems solved by technology

[0005] At this stage, the temperature control sponges are mostly prepared by spraying additives. The sponge products produced in this way have poor temperature control effect, and the requirements for the subsequent process are relatively strict, and the temperature control additives are mostly sprayed on the surface of the sponge, which is difficult to achieve the overall Excellent temperature control effect, poor washability

Embodiment 1

[0031] A temperature control sponge, prepared by weight from the following components,

[0032] 70 parts of polyether polyol, 30 parts of grafted polyether, 50 parts of toluene diisocyanate, 0.3 parts of triethylenediamine, 0.28 parts of stannous octoate, 1.5 parts of silicone oil, 1 part of methylene chloride, 3 parts of flame retardant, aromatic Family chain extender HQEE 2 parts, water 3.5 parts, white wax 5 parts.

[0033] The specific steps of the preparation method are as follows:

[0034] 1) Heat the white wax into a liquid, then add the aromatic chain extender HQEE, mix well and keep the temperature at 60°C;

[0035] 2) Mix the remaining raw materials evenly, and control the temperature at 28°C;

[0036] 3) Mix the mixture of step 1) and step 2) together, stir and react, and the stirring speed is 3000-4000 rpm;

[0037] 4) Naturally cool to 35° C. after the reaction is completed, and keep at this temperature and an environment with a relative humidity of 60% for 24 ...

Embodiment 2

[0039] 75 parts of polyether polyol, 25 parts of graft polyether, 60 parts of toluene diisocyanate, 0.45 parts of triethylenediamine, 0.45 parts of stannous octoate, 1.9 parts of silicone oil, 3 parts of methylene chloride, 4 parts of flame retardant, aromatic Family chain extender HQEE 3 parts, water 4 parts, white wax 8 parts.

[0040] The preparation method is the same as in Example 1.

Embodiment 3

[0042] 80 parts of polyether polyol, 20 parts of graft polyether, 65 parts of toluene diisocyanate, 0.6 parts of triethylenediamine, 0.6 parts of stannous octoate, 2.3 parts of silicone oil, 5 parts of methylene chloride, 5 parts of flame retardant, aromatic Family chain extender HQEE 4 parts, water 4.5 parts, white wax 10 parts.

[0043] The preparation method is the same as in the examples.

[0044] The temperature control sponge prepared in embodiment 2 carries out the temperature control effect test, and the test results are as follows: figure 1 As shown, the comparison product in the test is an ordinary sponge of the same density; description: from figure 1 It can be seen that the temperature-controlled sponge of the present invention can effectively suppress temperature changes, and its curve is relatively gentle, reflecting that when the temperature rises, the temperature-controlled sponge heats up slowly, and can be kept at 27 degrees Celsius for a period of time, and...

Abstract

The invention relates to a temperature control sponge. The temperature control sponge is prepared from, by weight, 70-80 parts of polyether polyol, 20-30 parts of graft polyether, 50-65 parts of toluene diisocyanate, 0.3-0.6 part of triethylenediamine, 0.28-0.6 part of stannous octoate, 1.5-2.3 parts of silicone oil, 1-5 parts of dichloromethane, 3-5 parts of a fire retardant, 2-4 parts of an aromatic chain extender HQEE, 3.5-4.5 parts of water and 5-10 parts of white wax. According to the temperature control sponge, the aromatic chain extender HQEE makes the temperature control agent (white wax) uniformly dispersed into other materials, so that the stabilizing effect is achieved; the sponge is maintained for 24 h after being prepared, so that the posture of the sponge is effectively sterilized, it is guaranteed that the temperature control agent can be uniformly distributed in the sponge, and processing in a subsequent procedure is promoted; intergrowth of the temperature control agent and the sponge is achieved, the temperature control agent is uniformly distributed in the sponge, phase change can happen in the sponge continuously to achieve the purpose of temperature control, and meanwhile the temperature control point is limited within 25 DEG C at which the human body feels comfortable.

Description

technical field [0001] The invention belongs to the technical field of sponge preparation, in particular to a temperature-controlled sponge and a preparation method thereof. Background technique [0002] Sponge products are widely used in all aspects of life, and their comfort is usually improved by using the hardness and rebound of sponges. [0003] The air conditioner can control the temperature, but it still needs to be set manually, and the energy consumption is high! [0004] The water beds that appear on the market also have the problem of high cost and low life, and are mainly suitable for summer. Similarly, electric blankets still have limitations. [0005] At this stage, the temperature control sponges are mostly prepared by spraying additives. The sponge products produced in this way have poor temperature control effect, and the requirements for the subsequent process are relatively strict, and the temperature control additives are mostly sprayed on the surface o...
