Embodiment 1

[0072] Example 1 Method for producing foamed fiberboard from fast-growing carbon sequestration grass

[0073] The foamed fiberboard produced by using fast-growing carbon sink grass has the advantages of low density, high strength, low water absorption, acid resistance, alkali resistance, heat insulation, sound insulation, good thermal insulation performance, shock resistance, easy molding, and no biodegradation. Settlement and lateral pressure, keep the road surface stable and the underground drainage system unimpeded. In mountainous areas with a lot of rain and snow, it can reduce the erosion of roadbed by rain and snow, prevent local subsidence of road surface, improve slope stability, and reduce landslides and freezing phenomena.

[0074] Its production steps are:

[0075] (1) Harvest when the lower 2 / 3 leaves of the fast-growing carbon sink grass plant start to wither, or when the leaves on the top of the plant dry up;

[0076] (2) For the fast-growing carbon seques...

Embodiment 2

[0081] Example 2 Method for producing composite wall with fast-growing carbon sequestration grass

[0082] With the destruction and reduction of natural resources such as forest farmland, traditional brick and wood structure buildings are gradually replaced by cement materials and steel materials. The fast-growing carbon sink grass composite wall adopts light steel structure, which has light weight, good thermal insulation performance, good sound insulation effect, and strong earthquake resistance. It is connected by bolts during construction, which is convenient and quick, and the construction period is short. There is no water in the construction process and less construction waste. It has little pollution to the environment, and can also reduce foundation treatment costs and transportation costs. Compared with traditional sintered clay bricks and concrete bricks, it saves soil and energy, and can also utilize industrial waste.

[0083] Its production steps are:

[0091] Example 3 Method for producing light-weight bricks and tiles from fast-growing carbon sequestration grass

[0092] Using fast-growing carbon-grass fiber and polyvinyl chloride (PVC) or recycled PVC as raw materials, the fast-growing carbon-grass lightweight bricks and tiles produced by foaming technology have stable physical and chemical properties, low thermal conductivity, and impact resistance. Waterproof, insect-proof, beautiful and practical.

[0093] Its production steps are:

[0094] (1) Harvest when the lower 2 / 3 leaves of the fast-growing carbon sink grass plant start to wither, or when the leaves on the top of the plant dry up;

[0095] (2) For the fast-growing carbon sink grass transported from the planting area, remove stones, sediment, iron wire, fiber rope and other debris;

[0096] (3) Crush the fast-growing carbon sequestration grass, and screen the fast-growing carbon sequestration grass particles through a 30-80 mesh sieve;

[0097] (4) Add the...

Abstract

The invention discloses a method for producing building materials and wood substitutes from fast-growing carbon sink grass. The fast-growing carbon sink grass is planted on barren hills and slopes, in marginal land and in polluted land required to be remedied, and biomass yield increase with leaps and bounds is realized through mowing; dynamic CO2 gas in the atmosphere is transferred to the biosphere, a static solid organic carbon compound is formed, excessive CO2 remaining in the atmosphere is allocated to the industry chain including production and storage of products with plants as a raw material, the concentration of CO2 in the atmosphere is adjusted, and global climate warming is inhibited. The method comprises steps as follows: (1) the planted fast-growing carbon sink grass is harvested at proper time; (2) the fast-growing carbon sink grass is pretreated according to the technical requirements of processing of foaming fiber boards, combined walls, lightweight brick tiles, flame-retardant thermal insulation boards, the wood substitutes and paper substitutes; (3) the foaming fiber boards, the combined walls, the lightweight brick tiles, the flame-retardant thermal insulation boards, the wood substitutes and the paper substitutes are produced. With grass to replace wood, deforestation is reduced, and the ecological environment is protected.

Description

technical field [0001] The invention belongs to the technical field of plant fiber utilization, and in particular relates to a method for manufacturing building materials and wood substitutes from fast-growing carbon sequestration grass. Background technique [0002] There is a shortage of forest resources in our country, and the supply of timber is tight. In order to protect the ecological environment and benefit future generations, the country has launched a natural forest protection project and implemented a logging ban. However, with the development of national economic construction and the improvement of people's living standards, the demand for building materials and timber continues to increase. In order to solve this contradiction, many new building materials and wood substitutes have been introduced on the market, such as foamed cement, light steel structure, and composite floor, but these products are high energy consumption products, and a large amount of CO is e...
