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

Embodiment 1

[0024] Mix 35 parts of natural rubber (parts by weight, the same below), 22 parts of hydrogenated rosin glyceride and 8 parts of dibutyl fumarate, grind to a paste with a colloid mill, add 0.2 parts of allyl triethoxysilane, continue Stir to mix the materials evenly to obtain a reactive non-bitumen-based waterproof composition, which can be directly used as a waterproof sealant.

Embodiment 2

[0026] 20 parts of butyl rubber (parts by weight, the same below), 20 parts of hydrogenated rosin pentaerythritol ester and 10 parts of dioctyl fumarate are mixed, ground to a paste with a colloid mill, and 0.5 parts of γ-(β-aminoethyl) are added Aminopropyltrimethoxysilane, 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

[0028] Mix 46 parts of isoprene rubber (parts by weight, the same below), 31 parts of glycerin rosin (softening point: 85-90°C) and 12 parts of dioctyl fumarate, grind to a paste with a colloid mill, add 1 part of γ -Chloropropyltrimethoxysilane, continue to stir to mix the materials uniformly to obtain a reactive non-bitumen-based waterproof composition, which is coated on a polymer film to make a waterproof membrane.

Abstract

The present invention provides a reaction typ enon-asphalt base waterproof composition. The composition is characterized by comprising the following raw materials in parts by weight: 20-60 parts of rubber; 20-40 parts of a tackifier; 8-15 parts of a softening agent; and 0.2-4 parts of a waterproof bridging agent. One end of the waterproof bridging agent can be combined with C=C double bonds or carboxyl (-COOH) of rubber, and the other end of the waterproof bridging agent can be bonded with acid radicals generated after cement is hydrated. A waterproof bridge is built, and very strong adhesive force is generated, so that glue and the cement are tightly bonded to form a firm waterproof layer.

Description

technical field [0001] The invention relates to a reactive non-asphalt-based waterproof composition, which is a waterproof material capable of chemically reacting with cement concrete to produce chemical crosslinking. 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;...
