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;...
