Problems solved by technology

[0004] (2) The papermaking and compounding of various pulps is mostly limited to the field of papermaking technology
[0006] (3) Multi-layer laminated net making is mostly limited to the field of papermaking technology
[0008] (4) The production of viscose pulp needs to be cooked and accompanied by a large amount of wastewater discharge
Moreover, pulp is only an intermediate product of the papermaking process, and there are great differences in product properties, textures, uses, etc.

Abstract

The invention provides a mixed pulp compound papermaking pulp substrate as well as a preparation method and an application thereof. The mixed pulp compound papermaking pulp substrate is prepared from following raw materials in parts by weight: 70-80 parts of bamboo pulp, 5-15 parts of reed pulp, 5-15 pats of cane syrup, 2-8 parts of fluff pulp and 0-2 parts of fly ash. The preparation method comprises the following steps: pulping, preparing the pulp, carrying out high-concentration degritting, grinding the pulp, carrying out low-concentration degritting, carrying out pressure screening, slushing, compounding and making paper with the pulp, drying and the like. The raw materials of the mixed pulp compound papermaking pulp substrate are selected from perennial wild herbaceous plants, processing industrial wastes, and fire coal wastes of power planes and industrial boilers; a product is uniform in texture and smooth in surface; no pollutants are discharged in a preparation process; water for diluting, agitating and conveying can be cyclically utilized; the mixed pulp compound papermaking pulp substrate provided by the invention can be used for producing electric mats and cockroach killing pieces or can be used as an industrial filtering material.
