Multicomponent high molecular composite construction sealing materials and production process thereof

Abstract

The invention relates to a building sealing material prepared by compounding a plurality of polymer materials and a method for preparing the same. The cross linkage in phase state is preformed on materials such as a ethylene-octylene multipolymer, polypropylene, a styrene elastic body, ethylene propylene diene rubber and a filler so that the processed material has the advantages of various polymer materials to make up the deficiency of various polymer materials; the advanced dynamic vulcanization reaction extrusion technology is adopted so that various polymer materials in a composition system are formed in a structure of crossing network and undergoes sufficient cross linkage; various polymer materials are scattered evenly in the polypropylene continuous phase in form of particles so that the processed building sealing material evidently improves the performances such as strength, elasticity, weather resistant property, compression resistance, and permanent deformation resistance, compared with the prior material; meanwhile, the antifatigue and anti-chemical product properties and the stability are improved evidently; the production technology is reliable, the maneuverability is strong, and the automation degree of production is high; therefore, the building sealing material has great pratical and popularized values.

Description

technical field [0001] The invention relates to a multi-component polymer composite building sealing material, in particular to a building sealing material prepared by compounding multiple polymer materials and a production method thereof. Background technique [0002] After retrieving relevant patent documents, no multi-element polymer composite building sealing material and its production method same as the present invention have been retrieved yet. At present, domestic building energy consumption accounts for 30% of total energy consumption, of which heating, air conditioning and ventilation energy consumption accounts for about 2 / 3, that is, heating, air conditioning and ventilation energy consumption accounts for 20% of total social energy consumption, about 440 million tons per year coal. The energy consumption per unit building area of ​​existing buildings in my country is 2 to 3 times that of developed countries, which has caused a heavy energy burden and serious en...
