Abstract

The invention discloses a process method for making a building material from straw fiber and pulp. A formula of the building material comprises the following components in percentage by mass: 60 to 80 percent of plant fiber, 5 to 15 percent of talcum powder, 5 to 15 percent of magnesium oxide and 5 to 15 percent of a modifying agent, wherein the modifying agent is composed of the following components in percentage by mass: 10 percent of sodium dodecyl benzene sulfonate, 30 percent of powdered activated carbon, 40 percent of pulping black liquor, 10 percent of sodium silicate and 10 percent of liquid paraffin. The straw fiber or the pulp serves as raw materials, and by utilizing the reduction characteristic of lignin, a produced building material product does not contain formaldehyde and any colloid, is non-toxic, tasteless, radiation-free, water-proof, damp-proof, fire-proof, sound-proof, thermally insulated, acid-base-resistant, ageing-resistant and moth-proof, and has the advantages of light weight, high strength, low cost and environmental protection.

Description

technical field [0001] The invention relates to the technical field of building material production and processing, in particular to a process for making building materials from straw fiber pulp. Background technique [0002] my country is a large agricultural country with extremely rich biomass resources. The annual output of crop straw alone reaches 700 million tons per year, of which nearly 200 million tons of rice straw accounts for about 30% of the straw resources. Most of these straws are discarded in the fields, or directly burned as living energy, resulting in waste of resources and environmental pollution. With the implementation of the national policy of prohibiting the logging of natural forests, the panel and building material production industries are facing great challenges. How to find new alternatives to natural wood to make building materials has become the only way for the industry to seek new raw materials to replace natural wood and develop new building m...
