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 Heat and 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] Mix 20 parts of butyl rubber (parts by weight, the same below), 20 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 vinyl triacetoxysilane, and continue heating Stir to mix the materials evenly to obtain a reactive non-bitumen-based waterproof composition, which is coated on a 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 rosin glyceride (softening point is 85-90°C) and 12 parts of dioctyl fumarate, grind it into a paste with a colloid mill, and add 1 part of γ -Diethylenetriaminopropyltrimethoxysilane, continue to heat and 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 a reaction type non-asphalt base waterproof composition. The composition is characterized by being composed of the following raw materials in parts by weight: 20 to 60 parts of rubber, 20 to 40 parts of tackifier, 8 to 15 parts of softening agent, and 0.2 to 4 parts of waterproof bridging agent. The composition can carry out chemical crosslinking reactions with concrete to generate a physical mortise and tenon cooperative bonding effect, a strong bonding force is generated, a waterproof bridge is generated, the glue and cement are tightly bonded, and a firm waterproof layer is formed.

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;...
