Embodiment 1

[0044] Taking the foaming pillow as an example, the process of using Eucommia latex and natural latex to make a foaming pillow includes the following steps:

[0045] (1) Get each raw material by the following parts by weight: Eucommia latex 30, natural latex 70, vulcanizing agent 0.6, accelerator 0.5, nucleating agent 7, antioxidant 0.2, activator 2;

[0046] (2) mix Eucommia latex and natural latex in (1), then add vulcanizing agent, promotor, nucleating agent, antioxidant, activating agent, adopt to mix with low-speed stirrer first, then adopt high-speed stirrer to mix; The rotation speed is 30rpm, the time is 5min, the rotation speed of the high-speed mixer is 100rpm, and the time is 3min; the above mixture is injected into the mold, vacuumized and filled with carbon dioxide, after foaming and vulcanization, washed with water, and the mold is opened when the mold is cooled to 10°C with super cold water. Take out the pillow core and dry it in an oven at 50° C. for 30 minutes...

Embodiment 2

[0050] (1) Get each raw material by the following parts by weight: Eucommia latex 30, natural latex 70, vulcanizing agent 0.6, accelerator 0.5, nucleating agent 7, antioxidant 0.2, activator 2;

[0051] (2) mix Eucommia latex and natural latex in (1), then add vulcanizing agent, accelerator, nucleating agent, antioxidant, active agent, adopt low-speed mixer to mix earlier, adopt high-speed mixer to mix again; The rotating speed of low-speed mixer It is 30rpm, the time is 5 minutes, the speed of the high-speed mixer is 100rpm, and the time is 3 minutes; inject the above mixture into the mold, vacuumize and fill with carbon dioxide, after foaming and vulcanization, wash with water, and open the mold when the mold is cooled to 10°C with super cold water , take out the pillow core and dry it in an oven at 50° C. for 30 minutes to obtain a foamed pillow core.

[0052] The conditions of the supercritical process are: pressure 10MPa, swelling time 3h, foaming temperature 60°C, pressu...

Embodiment 3

[0054] (1) Get each raw material by the following parts by weight: Eucommia latex 30, natural latex 70, vulcanizing agent 0.6, accelerator 0.5, nucleating agent 7, antioxidant 0.2, activator 2;

[0055] (2) mix Eucommia latex and natural latex in (1), then add vulcanizing agent, accelerator, nucleating agent, antioxidant, active agent, adopt low-speed mixer to mix earlier, adopt high-speed mixer to mix again; The rotating speed of low-speed mixer It is 30rpm, the time is 5 minutes, the speed of the high-speed mixer is 100rpm, and the time is 3 minutes; inject the above mixture into the mold, vacuumize and fill with carbon dioxide, after foaming and vulcanization, wash with water, and open the mold when the mold is cooled to 10°C with super cold water , take out the pillow core and dry it in an oven at 50° C. for 30 minutes to obtain a foamed pillow core.

[0056] The conditions of the supercritical process are: pressure 30MPa, swelling time 0.6h, foaming temperature 90°C, pres...

Abstract

The invention belongs to the technical field of latex material preparation, and particularly relates to a foaming material prepared from eucommia ulmoides latex and natural latex, a preparation methodof the foaming material and application of the foaming material to preparation of a latex pillow. The foaming material prepared by using the eucommia ulmoides latex and the natural latex is preparedby stirring and mixing the eucommia ulmoides latex and the natural latex, extruding, vacuumizing, injecting into a mold, charging supercritical CO2, vulcanizing, freezing and opening the mold. The foaming material has the beneficial effects that the foaming material, particularly the foaming pillow interior is prepared by combining the eucommia ulmoides latex and the natural rubber in a reasonableproportion range, and the foaming material, particularly the foaming pillow interior overcomes the defect that the pillow interior prepared by only taking the natural latex as a raw material is too soft due to the fact that the natural latex is too soft; and the foaming material or the foaming pillow interior is good in rebound resilience, not prone to deformation and good in supporting performance, has a shape memory function and is pleasant in user experience. And the process provided by the invention solves the problem of environmental pollution caused by adopting a chemical foaming agentin a common method.

Description

technical field [0001] The invention belongs to the technical field of latex material production, and in particular relates to a foaming material made by combining Eucommia latex and natural latex, a method for making the above-mentioned foaming material, and the use of the above-mentioned foaming material in making pillow cores or latex pillows. in the application. Background technique [0002] Regarding the production process of latex foam material or latex pillow core, the main process at present is to mix natural latex and synthetic latex, add vulcanizing agent, gelling agent, antioxidant, etc., stir with machinery, and add foaming agent at the same time, Fill the mold with foam, then send the mold into the steam chamber for vulcanization, and open the mold to take out the latex block. The main disadvantage is the use of chemical foaming agents, which is not environmentally friendly. Natural latex is easy to deform and cannot be restored after deformation. Moreover, nat...
