Problems solved by technology

[0003] my country is undergoing drastic development and changes, and there are more and more construction wastes. After demolition, a large amount of extruded panels are discarded as construction waste. However, the current extruded panels are difficult to degrade or degrade slowly under natural conditions. Moreover, some toxic and harmful substances will be released during the degradation process, which will seriously pollute the environment and affect environmental safety.

preparation example Construction

[0043] A preparation method of a degradable energy-saving extruded board, comprising: polystyrene, ceramic powder, hexabromocyclododecane, konjac glucomannan, vinyl acetate, methyl acrylate, talcum powder, hydroxypropyl Methyl cellulose, aluminum silicate, magnesium stearate and zinc stearate are first mixed to obtain mixed raw materials, and the mixed raw materials are first heated, and then sodium lauryl sulfate and fatty alcohol polyoxyethylene ether are added Sodium sulfate and ethanol are stirred to obtain an intermediate material, and the intermediate material is extruded to obtain an energy-saving and heat-retaining extruded board.

[0044] Further, the temperature of the first heating is 150-170°C.

[0045] Further, the stirring time is 25-35min.

Embodiment 1

Abstract

The invention provides a degradable energy-saving extruded sheet and a preparation method thereof, which belong to the field of energy saving and environment protection. The degradable energy-saving extruded sheet provided by the invention adopts konjac glucomannan as a material and a thermoplastic monomer as a grafting monomer, the konjac glucomannan is modified, and the energy-saving extruded sheet is then modified. The materials are conventional and easy to obtain, the properties of the extruded sheet are enhanced by combining the different materials, and thereby the extruded sheet has relatively good energy-saving and flame-retardant properties and is degradable and environment-friendly. The production process for the extruded sheet is simple and easy to implement, the condition is easy to control, the steps are simple, mass production is easy, and the invention has higher practical application value and popularization value.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection, in particular to a degradable energy saving extruded board and a preparation method thereof. Background technique [0002] Science and technology are progressing, the times are developing, with the continuous development of my country's economy and society, the continuous progress of society; and with the continuous deepening of my country's urbanization process, a large number of people have entered the city; my country has been in constant construction, especially After the reform and opening up; the problems of energy saving, heat preservation and environmental protection in the construction field have also attracted more and more attention. [0003] my country is undergoing drastic development and changes, and there are more and more construction wastes. After demolition, a large amount of extruded panels are discarded as construction waste. However, the current extrud...
