Negative ion bamboo charcoal latex foamed material and preparation method thereof

Abstract

The invention discloses a negative ion bamboo charcoal latex foamed material and a preparation method thereof. The foamed material comprises 10 to 15 wt% of natural latex, 60 to 70% of synthetic latex, 1 to 5 wt% of vegetable oleic acid potassium salt, 0 to 2% of castor oil potassium salt, 1 to 5% of aluminum hydroxide, 3 to 5 wt% of sulphur, 5 to 10 wt% of negative ion powder and 1 to 5 wt% of bamboo charcoal powder. According to the invention, a solid foamed material is formed through a foaming process and can be used as a support; since bamboo charcoal powder, negative ion powder, natural latex and synthetic latex are stirred and foamed at the same time, it is guaranteed that all the components undergo a same foaming procedure, so better uniformity and stability are realized; moreover, the foamed material can be poured on a planar conveyer belt except pouring into a die, so a finished product is not restricted by the size and shape of the die, thereby improving production efficiency and substantially reducing cost.

Description

technical field [0001] The invention relates to a negative ion bamboo charcoal latex foaming material and a preparation method thereof, which can be widely used in mattresses, cushions, pillows, sofas, insoles, bras and other products that are in close contact with the human body, thereby playing a beneficial effect on human health . Background technique [0002] [0003] Because of its natural and antibacterial properties, latex is widely used in daily necessities and medical and health fields, such as bedding, baby pacifiers, etc. Latex is generally formed by evaporation molding, and it has numerous pores, which is good in air permeability and due to the pores The surface is smooth, so mites, etc. cannot attach, which is a very good environmental protection material. [0004] Negative ions also have a health care effect. In different regions, the number of negative ions in the air varies greatly. According to the measurement, there are about 1,000 negative ion...

AI Technical Summary

Problems solved by technology

[0005] Negative ion technology has been applied to textiles in the prior art. Generally, bamboo charcoal powder is placed in the remaining materials in a separate small package. The disadvantages are poor uniformity and unstable structure or simply mixed in a liquid state. Produces an adequate blend of physical properties to form a stable structure
