Preparation method of environment-friendly novel building block material

Abstract

The invention belongs to the technical field of environment-friendly building block materials, and particularly relates to a preparation method of an environment-friendly novel building block material. According to the preparation method, the environment-friendly novel building block material is prepared by using magnesium cement, corn straw particles, coal ash, diatomite, slag powder, sodium methylsilicate, standard sand and urea resin as raw materials. The building block material prepared by the preparation method is low in weight, excellent in mechanical property, good in heat preservationperformance, low in water absorption, low in cost and simple in manufacturing process, and can be industrially produced; the building block material prepared by the preparation method is low in weight, the weight is only 610 kg / m<3>, in addition, the compressive strength and the breaking strength are excellent, and the toughness and crack resistance of the material are improved; the slag powder with the specific surface area being 8000 cm<2> / g is added into the building block material prepared by the preparation method, and the mechanical property and water resistance of the material are effectively provided; and the building block material is prepared by adopting the corn straw particles, the heat conductivity coefficient of the material is decreased significantly, and the thermal insulation performance is improved.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly block materials, and in particular relates to a preparation method of an environment-friendly novel building block material. Background technique [0002] Greening is the development trend of new building materials. Green building materials refer to building materials with attributes such as environmental protection, energy saving, health, safety, reliability, and renewability. or recycling, as well as waste treatment and other links to carry out pollution control design, select non-toxic and harmless raw materials, reduce pollution as much as possible in the production process, and recycle by-products as much as possible. Should produce pollution and threats to the environment and human health. my country is a large agricultural country with rich agricultural and sideline products and a large number of varieties. The total amount of crop straw in my country exceeds 700 million tons,...

Problems solved by technology

[0003] my country is rich in crop straw resources. In 2015, the amount of collectable resources of major crop straws in the country reached 900 million tons. However, the comprehensive utilization rate of crop straws in my country is low. The surplus of straws has caused a series of social problems such as straw burning and road safety. Through scientific and technological innovation , research and development of high-value comprehensive utilization technology of crop straws, and promote the sustainable development of agricultural production in my country has become a hot issue that the whole society pays close attention to and urgently needs to be solved.
