Thermal insulation material and connecting device thereof

Abstract

The invention discloses a thermal insulation material and a connecting device thereof, relates to the technical field of building outer wall thermal insulation, and aims at solving the problem that the balance between the vulcanization speed and the foaming speed of an existing thermal insulation material is unbalanced. The thermal insulation material includes a body and the connecting device, wherein the body is composed of an aluminum foil heat insulation layer, rubber-plastic sponge and an expanded polystyrene board; the rubber-plastic sponge is formed by sequentially adding ethylene propylene diene monomer, stearic acid, semi-reinforcing furnace black, calcium carbonate, paraffin oil, zinc oxide, calcium oxide, sulfur, an accelerant and a foaming agent into an internal mixer for internal mixing and natural vulcanization. The connecting device is installed between the bodies, a movable block is installed on one side of the interior of the connecting device, fixing openings are formed in the connecting device and the movable block, and one side of each body extends into the corresponding fixing opening. According to the invention, equilibrium between the vulcanization speed and the foaming speed of sponge rubber is achieved, and the phenomena of scorching and blooming are avoided on the premise that the vulcanization efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of thermal insulation of building exterior walls, in particular to a thermal insulation material and a connecting device thereof. Background technique [0002] Heat insulation materials, materials that can block the transfer of heat flow, also known as heat insulation materials, heat insulation materials are divided into three categories: porous materials, heat reflective materials and vacuum materials. The former uses the pores contained in the material itself to insulate heat, because the thermal conductivity of air or inert gas in the pores is very low, such as foam materials, fiber materials, etc.; heat reflective materials have a high reflection coefficient and can reflect heat, such as Gold, silver, nickel, aluminum foil or metal-plated polyester, polyimide film, etc. Vacuum insulation materials use the internal vacuum of the material to block convection and insulate heat. [0003] At present, in ter...
