specific Embodiment approach 1

[0016] Specific implementation mode 1: This implementation mode is a kind of degradable biomass composite matrix board, which consists of 20 to 40 parts of corn stalks, 15 to 30 parts of hemp stalk cores, 10 to 35 parts of waste paper pulp, and 15 to 30 parts by weight. It is made of 45 parts of animal manure, 1-2 parts of silicon airgel, 10 parts of binder, 2-3 parts of release agent, 3-5 parts of auxiliary materials and 2-3 parts of silane crosslinking agent.

specific Embodiment approach 2

[0017] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: the waste paper pulp uses waste newspaper or waste corrugated paper as raw material, first disintegrates it with a pulper, then soaks and swells, and then disperses it with a decomposer. Water is added to pulp and decompose to obtain waste paper pulp; the mass fraction of solids in the waste paper pulp is 5% to 10%. Others are the same as the first embodiment.

specific Embodiment approach 3

[0018] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the binding agent is one or more of starch, kaolin, carboxymethyl cellulose, gelatin and polyhydroxyalkanoate. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a degradable biomass composite matrix plate and a preparation method thereof, and relates to a degradable matrix plate. The invention aims to solve the problems of high cost, severe pollution and nutrient deficiency of an existing plastic seedling tray. The degradable biomass composite matrix plate is prepared from corn stalks, china-hemp stalk cores, waste paper pulp, animal feces, silica aerogel, a binding agent, a release agent, auxiliary materials and a silane cross-linking agent. The preparation method comprises the following steps of S1, preparing waste paper pulp; S2, carrying out weighing; S3, carrying out thoroughly decomposing to obtain thoroughly decomposed corn stalks and thoroughly decomposed china-hemp stalk cores; S4, carrying out mixing to obtain a defibering product; and S5, carrying out molding to obtain the degradable biomass composite matrix plate. The degradable biomass composite matrix plate and the preparation method thereof has the advantages that a rice composite seedling nursing tray prepared from the degradable biomass composite matrix plate can provide nutrition for crops and promote the growth of the crops, and the rice compositeseedling nursing tray has the effect of obviously improving the soil state after being degraded in soil. The preparation method is mainly used for preparing the degradable biomass composite matrix plate.

Description

technical field [0001] The invention relates to a degradable matrix plate. Background technique [0002] With the development of the industrialization of biomass materials in my country, the production of biodegradable materials using biomass resources as raw materials has become a hot research topic. my country is a large agricultural country with a large scale of production. The recycling of crop by-products and the pollution of straw burning have become one of the key factors restricting the development of my country's agriculture. Traditional plastic seedling trays have poor degradation performance, low recycling efficiency, and white pollution, and plastic seedling trays hinder plants from absorbing water and root growth, resulting in low survival rates and resulting in crop yield reduction. Contents of the invention [0003] The purpose of the present invention is to solve the problems of high cost, heavy pollution and lack of nutrition in the existing plastic seedl...
