Temperature control sponge and preparation method thereof

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, and particularly relates to a temperature control 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 the hardness and resilience of the sponge.

[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 on the market also have the problem of high cost and low life, and they are mainly suitable for summer. In the same way, electric blankets still have limitations.

[0005] At this stage, temperature control sponges are mostly prepared by spraying additives. The sponge products produced in this way have poor temperature control effects and require more stringent requirements for the subsequent procedures. Moreover, temperature control additives are mostly sprayed on the surface of the ...

Examples

Embodiment 1

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

[0032] 70 parts of polyether polyol, 30 parts of grafted polyether, 50 parts of toluene diisocyanate, 0.3 parts of triethylene diamine, 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 it evenly and keep it at 60°C;

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

[0036] 3) Mix the mixture of step 1) and step 2) together, and stir the reaction at a stirring speed of 3000-4000 revolutions / min;

[0037] 4) After the reaction is completed, it is naturally cooled to 35°C and kept at this temperature and a relative humidity of 60% for 24 hours.

Embodiment 2

[0039] 75 parts of polyether polyol, 25 parts of grafted polyether, 60 parts of toluene diisocyanate, 0.45 parts of triethylene diamine, 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 grafted polyether, 65 parts of toluene diisocyanate, 0.6 parts of triethylene diamine, 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 the example.

[0044] The temperature control sponge prepared in Example 2 was tested for the temperature control effect, and the test results are as follows figure 1 As shown, the comparison product in the test is an ordinary sponge with the same density; description: figure 1 It can be seen that the temperature control sponge of the present invention can effectively suppress temperature changes, and its curve is relatively gentle, reflecting that when the temperature rises, the temperature control sponge has a slower heating speed, can be maintained at 27 degrees Celsius for a period of time, and will al...
