Embodiment 1

[0073] The embodiment of this application provides the first plant fiber-based controllable water-permeable material, and the specific preparation method is as follows:

[0074] Mix waste paper fiber slurry, polyamide polyamine-epichlorohydrin resin, carboxymethyl cellulose and styrene-acrylic acid ester, form it by wet method, and then dry it by hot pressing to obtain a controllable plant fiber base. Permeable material, labeled Sample 1.

[0075] Wherein, the addition of polyamide polyamine-epichlorohydrin resin is 1.5% of the dry pulp quality of waste paper fiber slurry; the addition of styrene-acrylate is 1.5% of the dry pulp quality of waste paper fiber slurry. 5%; the added amount of carboxymethyl cellulose is 0.5% of the weight of the dry pulp of waste paper fiber pulp. The beating degree of the waste paper fiber slurry is 30°SR, the drying method is hot-press drying, the drying temperature is 180°C, and the drying time is 20 minutes.

Embodiment 2

[0077] The embodiment of this application provides the second plant fiber-based controllable water-permeable material, and the specific preparation method is as follows:

[0078] Take agricultural straw fiber slurry, alkyl ketene dimer, styrene-acrylic ester and polyamide polyamine-epichlorohydrin resin, mix them, use wet papermaking to form paper, and then dry in an oven to obtain plant fiber base The controllable water-permeable material is marked as sample 2.

[0079] Wherein, the addition amount of polyamide polyamine-epichlorohydrin resin is 2% of the dry pulp mass of agricultural straw fiber slurry; the addition amount of alkyl ketene dimer is the dry pulp of agricultural straw fiber slurry 0.5% of the mass of the material; the addition of styrene-acrylate is 4% of the dry mass of the agricultural straw fiber slurry. The beating degree of the agricultural straw fiber slurry is 40°SR, the drying method is oven drying, the drying temperature is 160°C, and the drying time ...

Embodiment 3

[0081] The embodiment of this application provides the third plant fiber-based controllable water-permeable material, the specific preparation method is as follows:

[0082] The waste paper fiber slurry, urea-formaldehyde resin, cationic polyacrylamide and styrene-acrylate were mixed, formed by wet method, and then dried by hot pressing to obtain a plant fiber-based controllable water-permeable material, marked as sample 3.

Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a plant fiber-based controllable permeable material and a preparation method thereof. The plant fiber-based controllable permeable material is prepared by the following steps: mixing plant fiber pulp, a water repellent agent and a reinforcing agent to obtain a mixed paper material; carrying out wet-process papermaking and shaping on the mixed paper material, and then drying to obtain the plant fiber-based controllable permeable material. The addition amount of the water repellent agent is 0.1%-28% of the absolute dry mass of the plant fiber pulp; the addition amount of the reinforcing agent is 0.2%-10% of the absolute dry mass of the plant fiber pulp; the water repellent agent is selected from one or more of paraffin, rosin, alkyl ketene dimer, alkenyl succinic anhydride, styrene-maleic anhydride copolymer and styrene-acrylate. The plant fiber-based controllable permeable material can effectively overcome the technical defects that a traditional water storage container made of plastic cannot be degraded in nature, and thus environmental pollution is caused, and the irrigation rate of the water storage container cannot be controlled.

Description

technical field [0001] The application belongs to the technical field of environmental protection, and in particular relates to a plant fiber-based controllable water-permeable material and a preparation method thereof. Background technique [0002] In the arid areas of Northwest my country, the key factor affecting plant growth is soil moisture. However, due to regional water shortages, low rainfall, and serious soil erosion, it is difficult for plants to be effectively irrigated, and the growth and survival rate is very low, which brings great harm to ecological transformation. great difficulty. [0003] In arid areas, the irrigation of the roots of plants buried in the soil generally adopts the leakage irrigation method of the water storage container to avoid the lack of water for the plants. However, the existing plastic water storage containers are not biodegradable in nature. At the same time, when the plants are irrigated, the plastic water storage containers cannot e...
