Embodiment 1

[0044] Embodiment 1 Preparation of memory foam A

[0045] First, after dissolving 0.4kg of stannous octoate with 2.7kg of water, add 48kg of polyether polyol, 24kg of diphenylmethane diisocyanate (MDI), and 6kg of diatom powder in a blender. Polymerization reaction starts during the process. When the reaction temperature rises to 100 degrees, add 1.7kg of water-soluble silicone oil, 0.5kg of triethylenediamine and 2.5kg of polypropylene glycol (PPG350), continue to stir and mix well, and then pour it into the shaping tank , leveling, and continue the polymerization reaction. After the reaction is completed, memory foam A is obtained after natural cooling.

[0046] The main technical parameters of this memory foam A are:

[0047] 1. When the external pressure ΔP=90Pa, the recovery time after removal is Δt=5-6 seconds, while the recovery time of ordinary sponge is 1-2 seconds;

[0048] 2. The indentation strength is 1431b. / sq.in (25);

[0049] 3. Thermal conductivity 0.03W / m; ...

Embodiment 2

[0053] The preparation of embodiment 2 memory foam B

[0054] First, after dissolving 0.1kg of stannous octoate with 2.5kg of water, put 47kg of polyether polyol, 25kg of diphenylmethane diisocyanate (MDI), 2kg of diatom powder, and stannous octoate solution in In the mixer, the polymerization reaction starts during the stirring process. When the reaction temperature rises to 70 degrees, add 1kg of water-soluble silicone oil, 0.5kg of triethylenediamine and 2.5kg of polypropylene glycol (PPG350), and then continue to stir and mix well. Pour it into a shaping tank, level it, and continue the polymerization reaction. After the reaction is completed, the memory foam B is obtained after natural cooling.

[0055] The main technical parameters of this memory foam B are:

[0056] 1. When the external pressure ΔP=90Pa, the recovery time after removal is Δt=5-6 seconds, while the recovery time of ordinary sponge is 1-2 seconds;

[0057] 2. The indentation strength is 1431b. / sq.in (25...

Embodiment 3

[0062] The preparation of embodiment 3 memory foam C

[0063] First, after dissolving 0.5kg of stannous octoate with 3kg of water, put 57kg of polyether polyol, 28kg of diphenylmethane diisocyanate (MDI), 8kg of diatom powder, and the stannous octoate solution under stirring In the container, the polymerization reaction starts during the stirring process. When the reaction temperature rises to 130 degrees, add 2kg of water-soluble silicone oil, 1.0kg of triethylenediamine and 3.0kg of polypropylene glycol (PPG350), continue stirring and mixing, and pour Put into the shaping tank, level off, continue the polymerization reaction, after the reaction is completed, memory foam C is obtained after natural cooling.

[0064] The main technical parameters of this memory foam C are:

[0065] 1. When the external pressure ΔP=90Pa, the recovery time after removal is Δt=5-6 seconds, while the recovery time of ordinary sponge is 1-2 seconds;

[0066] 2. The indentation strength is 1431b. / ...

Abstract

The invention provides a negative ion polyurethane memory foam composition. The memory foam composition comprises 47-57wt% of polyether polyol, 25-28wt% of methyl diphenylene diisocyanate (MDI), 0.1-0.5wt% of stannous octoate, 1-2wt% of water-soluble silicone oil, 0.5-1.0wt% of triethylenediamine, 0.5-3.0wt% of polypropylene glycol (PPG350), and the balance of water. The composition can also comprise 2-8wt% of diatom powder. The invention also provides a preparation method and an application of the composition. Memory foam made by using the composition has a slow rebound performance, and has breathing, ventilating and blood circulation improving effects, and the memory foam containing the diatom powder can release negative ions.

Description

technical field [0001] The invention relates to a composition, in particular to a memory foam composition and a production method thereof. Background technique [0002] Memory foam is composed of many tiny particles. After touching the body temperature, it will naturally soften and sink with the shape of the body, and evenly distribute the pressure area, so that the human body can be comfortably supported. Memory foam is a functional polymer material and a new branch of research, development and application of polymer materials. With the deepening of the understanding of polymer structure and characteristics, and the development of polymer synthesis technology, it has become a reality to obtain the expected structure and performance of polymer materials through molecular design. [0003] Memory foam is the use of modern molecular physics and polymer synthesis and modification technology to carry out molecular combination and modification of general polymer materials. For e...
