Problems solved by technology

[0012] But at present, most of the activated carbons appear in the form of charcoal bags, which are ugly in appearance, and the activated carbon is easy to leak from the charcoal bags.
However, making activated carbon into a solid block and maintaining its adsorption performance requires a more complicated process and higher cost

Embodiment 1

[0051] Such as figure 1 A kind of adsorption PM2.5 shown and the preparation method of rice-wheat straw activated carbon ecological building material for radiation protection include the following steps:

[0052] Step 1, mixing raw materials: fully mix 65 parts of rice straw activated carbon powder, 20 parts of rice straw fiber, and 15 parts of glutinous rice crosslinking agent to form a mixture;

[0053] The preparation method of described rice straw activated carbon powder comprises the following steps:

[0054] 1-1) Rice and wheat straw selection and cleaning: collect newly harvested or within one year rice and wheat straw, remove moldy and rotten rice and wheat straw, and clean the soil and impurities on the straw;

[0055] 1-2) Drying: Expose or dry the cleaned rice and wheat straw; when drying, the drying temperature is 45°C-55°C; expose or dry until the water content of the rice and wheat straw is 9%-13% ;

[0056] 1-3) Pulverization: pulverize the dried rice and whe...

Abstract

The invention discloses a preparation method of a rice and wheat straw active carbon ecological building material for PM2.5 adsorption and radiation prevention. The preparation method comprises the following steps: 1, uniformly mixing raw materials; 2, weighing the raw materials; 3, hotly pressing a blank; 4, post-treating the blank. According to the preparation method, rice and wheat straws are utilized for making active carbon powder, so that the pollution of the rice and wheat straws on the environment is alleviated, the utilization rate of the rice and wheat straws is increased, and a preparation process for the active carbon ecological building material is simplified; the prepared active carbon ecological building material is firm and unlikely to be damaged, has relatively high adsorption property, can effectively adsorb PM2.5 particles, and has very high radiation-proof performance; the ecological building material can be applied to numerous fields of decorative materials, building materials, artware materials, wastewater treatment materials, air purification materials and the like.

Description

technical field [0001] The invention belongs to the field of handicrafts, and in particular relates to a production method of an ecological building material which is made of rice-wheat straw activated carbon powder to strongly adsorb indoor harmful gases and PM2.5, efficiently purify indoor air, and absorb radiation, purple and infrared rays of electrical appliances. Background technique [0002] The annual output of crop straw in our country reaches more than 700 million tons, but most of these resources are burned except for a small amount of feed, which not only causes a huge waste of resources but also causes serious environmental pollution. Rice straw contains a large amount of carbon sources and has high utilization value. Therefore, how to effectively use rice straw, reduce pollution, and improve resource utilization has always been a problem that people strive to solve. [0003] In recent years, people's living environment has gradually deteriorated. Vehicle exhaus...
