Embodiment 1

[0017] Embodiment 1 (see table 1 embodiment 1 raw material and its weight ratio value): the bamboo section material is dropped in the tubular moving bed retort carbonization furnace, the bamboo charcoal made by the method described in the preparation of the bamboo charcoal powder of step 1 105 parts of germanium powder, 20 parts of germanium stone powder, 10 parts of magnetite powder, 10 parts of tourmaline powder, 5 parts of starch and 25 parts of water are added one by one. into bamboo charcoal ore composite powder as an additive.

[0018] All the other examples 2-8 refer to the raw materials and proportioning values ​​of the corresponding examples in Table 1, and the same method as in Example 1 is used to obtain this bamboo charcoal ore composite powder, which is used as an additive, among which examples 1-3 are preferred.

[0019] The raw material and its weight portion proportioning value of producing semi-rigid polyurethane foam product are listed in Table 2 with eight e...

Embodiment 9

[0021] Embodiment 9 (see Table 2 Embodiment 9 raw materials and their weight ratio values): first add 105 parts of polyether polyols, then add 15 parts of bamboo charcoal ore composite powder, 15 parts of pentane, 5 parts of triethylenediethylene diethylene glycol one by one Mix well after amine, 5 parts of water and 5 parts of silicone oil, keep warm at 30-40°C, select a mold that matches the product to be made, such as a metal mold for a steering wheel of a car, heat it to 50-60°C, mix the above mixture with 120 parts Diisocyanate is injected into the metal mold at high speed and foamed for 5-15 minutes at the same time, and the semi-rigid polyurethane foam steering wheel is formed after demoulding.

[0022] For the rest of Examples 10-16, refer to Table 2 for the corresponding examples of raw materials and their weight ratios, and use the same method as Example 9 to prepare semi-rigid polyurethane foam products, among which Examples 9-11 are preferred.

Abstract

The invention relates to a production method for health-care semi-rigid polyurethane foams of bamboo charcoal composite powder, which is characterized by firstly preparing bamboo charcoal and ore composite powder, wherein the bamboo charcoal powder is prepared from charcoal and ore powder, wherein the charcoal is produced in a charing furnace with temperature controlling functions in fume drying and pre-charing, primary charing and calcining and refining stages and the temperature of a highest-temperature zone is up to 700-1000 DEG C; the ore powder is selected from germanium ore powder, magnetite powder and tourmaline powder; and the obtained bamboo charcoal and ore composite powder has a particle size of 800-1000 mesh, and can emit far infrared rays which have the wavelengths of 4-14 mu m and 8-10 mu m and are the most suitable for human body absorption and a large amount of negative oxygen ions; and using the composite powder as an additive to produce the semi-rigid polyurethane foams. The obtained product has high absorptivity and strong sweat absorption and deodorization properties; and when a user is in close contact with the product, the user accepts far-infrared radiation and absorbs oxygen in a small environment rich in far infrared rays and negative ions, thus promoting blood circulation, increasing blood oxygen content, reducing fatigue and being beneficial to human health.

Description

technical field [0001] The invention relates to a production method of a semi-rigid polyurethane foam with a powder beneficial to human health as an additive. Background technique [0002] Polyurethane foam materials have been widely used in people's daily life, such as interlayer materials for carriages, seats, beds, pads, etc. Most of them use their porous and elastic characteristics to give people a soft and comfortable feeling. But although common foam material can absorb moisture, it is not easy to distribute moisture, and it is easy to breed germs due to dirt holding and smelly. CN1865236 discloses "a kind of bamboo charcoal sponge and its preparation method". The bamboo charcoal contained in the sponge contains 15%-50% , the proportion is high, which affects the maintenance of the original characteristics of the sponge, and the bamboo charcoal has not been specifically processed and selected, and the relevant excellent characteristics of the bamboo charcoal cannot be ...
