Problems solved by technology

Since this technology needs to add micron-sized wear-resistant particles to ensure its installation strength, it will also have a negative impact on the foaming process in the subsequent co-extrusion granulation process, resulting in a relatively low yield of co-extrusion granulation; and because The large specific surface area of ​​nanomaterials is difficult to add, and the premixing of nanomaterials with natural rubber will also have a negative impact on the durability of the rubber structure itself.

Abstract

The invention discloses an ALG nano rubber-plastic heat-preservation and sound-insulation plate, which is prepared from the following raw materials in parts by weight: 35 to 55 parts of natural plantrubber; 25-45 parts of a nano reinforced heat preservation composite agent; 4-10 parts of a foaming agent; and 5-10 parts of a plasticizer; wherein the nano reinforced heat preservation composite agent is prepared by stirring and mixing 10-40% by weight of nano TiO2 or nano SiO2 and 60-90% by weight of a filler in a closed container at a high speed; the stirring speed is not lower than 800 r / min,and the stirring time is not shorter than 5 minutes. The invention further relates to a processing method of the ALG nanometer rubber-plastic heat-preservation and sound-insulation plate. The ALG nanorubber-plastic heat-preservation and sound-insulation plate has the advantages of less raw material consumption, high processing yield, excellent durability, light weight, heat insulation, high mounting strength, excellent sound-insulation and flame-retardant effects, simple preparation process and easiness in batch production and implementation.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an ALG nano-rubber-plastic thermal insulation and sound-insulation board, and also relates to a processing method of the ALG nano-rubber-plastic thermal insulation and sound-insulation board. Background technique [0002] With the improvement of people's requirements for green and energy-saving living environment, various noises have brought a huge threat to residents living in cities, especially residential residents in complex environments are most affected. How to solve the impact of urban noise and strengthen the anti-noise ability of residential buildings has become an important problem facing the central residential area. [0003] However, the current conventional green ecological residential quarters only focus on greening, waterscape and other hard landscapes as the focus of environmental construction, and pay less attention to the construction of physical en...
