Problems solved by technology

[0003] The above several reactive adhesive waterproofing materials are all asphalt-based waterproofing materials, because the composition of asphalt is complex, and the composition of asphalt obtained from different crude oils is different, which often leads to unstable performance of asphalt waterproofing materials, and often needs to be adjusted for different asphalt raw materials Production formula and production process, resulting in low production efficiency and increased production costs
However, there are few reports on the application of reactive adhesive waterproofing technology in non-bitumen-based waterproofing materials.

Embodiment 1

[0016] Mix 60 parts of natural rubber (parts by weight, the same below), 29.7 parts of hydrogenated rosin glyceride and 10 parts of dibutyl fumarate, grind to a paste with a colloid mill, add 0.3 parts of vinyl triacetoxysilane, and continue stirring to make The materials are mixed evenly to obtain a reactive non-bitumen-based waterproof composition, which can be directly used as a waterproof sealant.

Embodiment 2

[0018] Mix 60 parts of butyl rubber (parts by weight, the same below), 29.5 parts of hydrogenated rosin pentaerythritol ester and 10 parts of dioctyl fumarate, grind to a paste with a colloid mill, add 0.5 parts of N-(4-aminobutyl) Aminomethyltriethoxysilane, continue to stir to mix the materials evenly to obtain a reactive non-bitumen-based waterproof composition, which is coated on polyester non-woven fabric to make a waterproof membrane.

Embodiment 3

[0020] Mix 60 parts of isoprene rubber (parts by weight, the same below), 27 parts of glycerin rosin (softening point is 85-90°C) and 10 parts of dioctyl fumarate, grind it into a paste with a colloid mill, add 3 parts of γ -Chloropropyltrichlorosilane, continue to stir to mix the materials evenly to obtain a reactive non-bitumen-based waterproof composition, which is coated on a polymer film to make a waterproof membrane.

Abstract

The invention provides an application of a waterproof bridging agent in a non-asphalt base waterproof material. The waterproof bridging agent accounts for 0.3 to 3% of the sticker in non-asphalt base waterproof material, and is used as the crosslinking agent of non-asphalt base waterproof glue, so the waterproof agent can carry out chemical crosslinking reactions with the cement surface, the bonding force between the waterproof glue and cement surface is enhanced, the binding strength between the waterproof material and the surface is increased, and the weatherability of the waterproof material is improved.

Description

technical field [0001] The invention relates to the application of a waterproof bridging agent in non-bitumen-based waterproof materials. Background technique [0002] The so-called reactive adhesive waterproofing technology relies on the waterproofing material of the waterproofing layer and the cement concrete to have a chemical cross-linking reaction and a physical mortise and tenon synergistic bonding effect to produce a strong cohesive force, so that the waterproofing layer and the concrete base are closely connected to form a waterproof layer. Skin-like waterproof layer. Reactive adhesive waterproof technology has been successfully applied to various waterproof materials, such as the Chinese patent applied by the inventor: application (patent) number: CN200910114456.X, name: waterproof roll with chemical crosslinking and physical mortise and tenon synergistic bonding with concrete material; public (announcement) number: CN101694114A applicant (patent) person: Guangxi G...
