Abstract

The invention discloses a straw fireproofing and heat-insulating board and a production method thereof, belonging to the technical field of buildings. The straw fireproofing and heat-insulating board consists of the following raw materials: 20-40 parts of phenolic resin particles, 40-80 parts of straw, 1-5 parts of latex powder, 5-10 parts of a fireproofing agent, 1-5 parts of water repellent, 0.1-1 part of a surfactant and 100-200 parts of water. The invention also provides a production method of the straw fireproofing and heat-insulating board, wherein the production method comprises the steps of mixing the raw materials, uniformly stirring, putting the mixed raw materials in a mold, demolding and aging. According to the straw fireproofing and heat-insulating board and the production method thereof disclosed by the invention, straw is taken as a main filling material to produce the heat-insulating board which is strong in capacity of resisting bending, pressure and fracture, high in fireproofing grade, convenient in construction and low in cost on the basis of the full utilization of the characteristics of the straw which is strong in filling capacity, high in fiber toughness and strong in fireproofing and heat-insulating capacities under the functions of the phenolic resin particles, the latex powder and the water repellent; and meanwhile, the problems on post-treatment and recycling of agricultural waste are solved.

Description

technical field [0001] The invention belongs to the field of construction technology, in particular to a straw fireproof insulation board and a production method thereof. Background technique [0002] At present, the construction industry is developing rapidly. Traditional building walls using concrete, solid bricks or hollow brick structures cannot meet people's needs because the walls are not insulated or insulated. Therefore, various insulation boards have emerged as the times require. Phenolic foam plastics have been widely used as thermal insulation materials, sound insulation materials, building decoration materials and high water absorption materials due to their characteristics of heat insulation, flame retardancy, low smoke generation during combustion, low toxicity and dimensional stability. At the same time, phenolic foam can be better used in external wall insulation systems due to its easy-to-obtain raw materials, low price, excellent product performance, flame ...
