Embodiment Construction

[0008] Below in conjunction with embodiment the present invention is further described

[0009] Method l: Bamboo charcoal 50%, tourmaline 50%. The production method is as follows:

[0010] (1) Calcining 5um tourmaline at 600°C for 2 hours;

[0011] (2) Fully mix calcined tourmaline and 300-mesh bamboo charcoal at a weight ratio of 1:1, and then put them into a jet mill for grinding, so that the particle size of the resulting mixed powder is 0.5um;

[0012] (3) Form the mixed powder under a pressure of 100MPa (generally ①50mm×l0mm), and then put it into a vacuum graphite sintering furnace and calcinate at 850°C for 5 hours in a vacuum environment to obtain a calcined product;

[0013] (4) Cool the calcined product to room temperature, and then cut it into shape after polishing.

[0014] Method 2: a He charcoal-tourmaline far-infrared composite material, the raw material formula composition weight percentage is: bamboo charcoal 50%, tourmaline 50%. The production method is a...

Abstract

The invention relates to a production method of a far infrared composite material. According to the production method, a far infrared material is produced and compounded from bamboo charcoal and tourmaline, and 50% of bamboo charcoal and 50% of tourmaline are compounded. The production method particularly comprises the following steps: (1) calcining tourmaline at 500-700 DEG C for 1-3 hours; (2) adequately mixing calcined tourmaline with bamboo charcoal according to a formula, and grinding until the particle size of mixed powder reaches 0.1-1 microns; (3) shaping the mixed powder at 90MPa-110MPa, and calcining the mixed powder at 850-1000 DEG C for 1-5 hours at a vacuum environment, so as to obtain calcined substances, wherein the shaped mixed powder has the size of 40-60mm * 7-13mm; and (4) cooling the calcined substances to room temperature, so as to obtain the composite material. The production method has the beneficial effects that the raw materials are easily available, a production process is simple and convenient, the production energy consumption is low, the production process meets environmental requirements, and the cost is low.

Description

technical field [0001] The invention relates to a production method of a far-infrared composite material, in particular to a far-infrared composite material with bamboo charcoal and tourmaline as raw materials and a production method thereof. Background technique [0002] At present, the far-infrared radiation emissivity of known far-infrared ceramic powders is relatively low, mostly between 0.7 and 0.85. At present, far-infrared materials at home and abroad generally use metal oxides, non-metal oxides and rare earth materials, and there is a high cost. Problems such as complex production process and single function. Therefore, it is an inevitable trend to develop far-infrared materials with higher emissivity, low cost, low energy consumption, and simple production process. Contents of the invention [0003] The invention provides a production method for producing far-infrared materials by compounding bamboo charcoal and tourmaline. The far-infrared composite material ha...
