Embodiment 1

[0009] Cut 5kg of flax stalks into 2cm sections, put them into a plant grinder and crush them into powders with a particle size of 1mm. The powder is placed on the turntable, the micro-wave rate is 150W, irradiated for 3 minutes, and the volume of the powder is expanded by 2-3 times. Take it out, cool it, and collect it for later use.

Embodiment 2

[0011] The same method as the previous example, measure the natural moisture content of 8%, spray water until the moisture content is 30%, put it into the container, control the power at 200W, and irradiate for 2 minutes, then the volume of the powder will expand 2-3 times, take it out, cool it, Gather spares.

Embodiment 3

[0012] Embodiment 3: The pulverized particle size is 1.8 mm, and the measured natural state moisture content is 20%, which is directly put into the container, and the method is the same as that of Embodiment 1, and the microwave power is controlled to be 300W, and the radiation is finalized for 1 min.

[0013] Various hemp stalks, corn sorghum stalks, and sunflower stalks are selected because they have a loose pith, which has better water absorption and expansion effects. The microwave oven with automatic power and time adjustment is selected because the power and temperature can be automatically adjusted according to the settings, so as not to cause insufficient foaming or coking.

[0014] If you want to use the above-mentioned plant fiber powder to further make foaming products such as fast food boxes, you should prepare the adhesive, lubricant, foaming agent, and auxiliary agents according to the set formula before foaming, and then foam them. This is done together with mol...

Abstract

The invention relates the preparing method of plant fiber expanded material, comprising the following steps: cutting and disintegrating plant fiber, putting it into microwave oven for 1-3min, cooling, and getting the product. The product can be used in many foaming products, such as mess-tin, heated board, acoustic Celotex board, basin, cup, packaging material, and so on. The invention has the advantages of uniformity, quick-speed, good effect and non-pollution.

Description

technical field [0001] The invention relates to a production method of a foaming material, in particular to a method for producing the foaming material by using plant fiber as the main raw material through electromagnetic wave radiation. Background technique [0002] Commonly used foaming materials are plastic foaming materials, and the destruction of the atmospheric ozone layer by fluorocarbons used in production and the non-degradability of products have brought far-reaching harm to human beings. For this reason, aspiring reformers have done extensive exploration and in-depth research, using plant fiber as the main raw material, through liquefaction, and then making polymer materials (polyurethane), producing hard foam, semi-rigid foam and soft foam materials, CN1528824A Patents disclose this. CN1079102C discloses Mr. Ji Buhua's "a foaming material made of plants" patent technology, which uses plant fibers, fruits, and non-toxic additives as raw materials, and is cut, sep...
