Problems solved by technology

[0005] The current molding decorative building materials mainly include wood, stone, sand, brick, tile, cement, gypsum, asbestos, lime, glass, mosaic, soft porcelain, ceramics, paint, paper, ecological wood, metal, plastic, fabric, etc. , but the performance of a single material often cannot meet the needs of use. The wooden structure is easy to corrode, the masonry structure is heavy and unsafe, and the strength and toughness of plastic products are not enough. Therefore, the use of renewable plant fibers to make molded decorative building materials has become a research topic today. hotspot

Embodiment 1

[0032] A preparation method of a composite plant fiber molding decorative building material:

[0033] Add dimethyl sulfoxide and tetraethylammonium chloride with a mass ratio of 5:1 into distilled water, stir and mix evenly to obtain a treatment solution, and raise the temperature to 50°C, then dry the flax fibers to constant weight at a ratio of 1:20 The solid-to-liquid ratio was added, stirred at a speed of 500r / min for 4 hours, the flax fibers were filtered out, washed thoroughly, and dried in an oven at 60°C for 10 hours to obtain modified flax fibers. After drying and dehydrating the bamboo charcoal fibers, they were added to dimethyl Add maleic anhydride and dimethylaniline to the base sulfoxide, stir and react at room temperature for 5 hours, then filter out the bamboo charcoal fibers, wash them with water, dry them, and transfer them to a muffle furnace under nitrogen protection at a temperature of 5°C / min. Slowly raise the temperature to 280°C and calcined for 50 minu...

Abstract

The invention provides a method for preparing a composite plant fiber molding decorative building material, which relates to the field of building materials and comprises the following steps: modifying flax fiber; modifying bamboo charcoal fiber; preparing a composite plant fiber prepolymer; prepolymerizing the composite plant fiber Add solid and nano-organic montmorillonite into distilled water, heat up to 70-90°C, stir and disperse rapidly at a speed of 1200-1400r / min for 60-80min, then add the compound emulsifier, continue stirring for 30-50min and then cool down to 40 ‑45°C, then add the mixed monomer composed of methyl methacrylate and butyl acrylate, stir for 20‑30min, then add ammonium persulfate aqueous solution dropwise, after the drop, raise the temperature to 80‑85°C, stir for 8‑10h, After adding demulsifier, suction filter, fully wash, vacuum dry and ball mill to get the base material; put the base material into the mold, heat up to 180-200°C under a certain pressure, keep the temperature and pressure for 40-60min, then cool to room temperature and demould. , The composite plant fiber molding decorative building material of the present invention has excellent mechanical strength.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method of a composite plant fiber molding decorative building material. Background technique [0002] The development and utilization of renewable biomass resources is considered to be one of the effective ways to alleviate resource crisis and solve environmental problems. At present, there are two main methods for the transformation and utilization of renewable plant resources: one is to directly use them to produce energy and chemicals, replacing energy such as oil, natural gas, coal and fossil-based chemical products; the other is to retain their excellent natural characteristics Under the premise, it is transformed into new high-value products through technical means such as modification and modification. [0003] At this stage, although the use of plant resources to produce new energy and chemicals is highly valued, its high technical difficulty and conversio...
