Abstract

The invention discloses a two-component polyurethane waterproof coating containing a non-polar polymer modified compound and a preparation method of the two-component polyurethane waterproof coating.The two-component polyurethane waterproof coating is prepared from a component A and a component B, wherein the component A is a polyurethane prepolymer prepared from 3-15 parts by weight of isocyanate and 2-40 parts by weight of first polyol; the component B comprises 2-20 parts by weight of second polyol, 2-30 parts by weight of the compound subjected to epoxidation modification with a non-polarpolymer, 2-15 parts by weight of a chain extender and 0.1-2 parts by weight of a catalyst, and a main chain of the non-polar polymer contains multiple C=C double bonds. The polyurethane waterproof coating has good performance of adhesion with a bituminous waterproof coiled material and a polymer waterproof coiled material and is used for adhesion, composition or repair of the bituminous waterproof coiled material or the polymer waterproof coiled material.

Description

technical field

[0001] The invention belongs to the technical field of waterproof materials, and more specifically relates to a two-component polyurethane waterproof coating containing a non-polar polymer modified compound and a preparation method thereof. Background technique

[0002] Waterproof materials are used as building envelopes to prevent the penetration of rainwater, snow and groundwater; to prevent the erosion of moisture, steam and other harmful gases and liquids in the air; to prevent the seepage of water supply and drainage as a separation structure. Turn; these anti-penetration, leakage and erosion materials are collectively referred to as waterproof materials. There are many kinds of waterproof materials, mainly including polyurethane waterproof coating, asphalt waterproof membrane, polymer membrane and other waterproof materials.

[0003] Polyurethane waterproof coating is a chemically reactive polymer waterproof coating with excellent performance. It is an...
