Expanded vermiculite reinforced EPDM/POE waterproof coiled material and preparation method thereof

Abstract

The invention relates to an expanded vermiculite reinforced EPDM / POE waterproof coiled material. The expanded vermiculite reinforced EPDM / POE waterproof coiled material is prepared from the following raw materials in parts by weight: EPDM, butyl rubber, POE, expanded vermiculite, 1,3-bis(tert-butylperoxide diisopropyl) benzene, triallyl isocyanurate, stearic acid, 2-mercapto benzimidazole, lanthanum oxide, methyl methacrylate, butyl acrylate, sodium dodecyl benzene sulfonate, zinc oxide, sodium persulfate, calcium carbonate, glyceryl stearate, zinc sulfate, 2,2-dithio bisbenzothiazole and deionized water. The waterproof coiled material can be folded in multiple angles, so that the quantity of joints is greatly reduced, and the water permeation probability can also be effectively reduced; and meanwhile, the expanded vermiculite reinforced EPDM / POE waterproof coiled material has heat insulating and energy-saving effect and is convenient to construct.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to an expanded vermiculite reinforced EPDM / POE waterproof coiled material and a production method thereof. technical background [0002] EPDM membrane is recognized as the waterproof membrane with the best comprehensive performance in the world, and EPDM has been used in a large number of Chinese construction projects because of its excellent physical properties. In recent years, with the advancement of social science and technology and the enhancement of people's awareness of environmental protection, the industry's requirements for building waterproof materials have changed from the previous single waterproof function to the multifunctional direction of long life, flame retardancy, and ozone aging resistance. At present, the EPDM waterproof membranes sold in the market are basically produced according to the national polymer waterproof membrane standards. When used on buildings, t...

AI Technical Summary

Problems solved by technology

At present, the EPDM waterproof membranes sold in the market are basically produced according to the national polymer waterproof membrane standards. When used on buildings, they have good waterproof effects and long working life. The fly in the ointment is that : Both the EPDM waterproof membrane and the waterproof layer used to generate it are easy to burn when exposed to open flames, so there are certain safety hazards, especially not suitable for waterproof and anti-corrosion projects for buildings with high fire protection requirements Therefore, it is not ideal from the perspective of practicality and economy
