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

[0019] 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 lauric acid rare earth compound, and continue stirring to mix the materials Evenly, a reactive non-bitumen-based waterproof composition is obtained, which can be directly used as a waterproof sealant.

Embodiment 2

[0021] 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 aluminum zirconate waterproof bridging agent, Continue stirring 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

[0023] 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 dioctyl Dioctyltin chloride, 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 a reaction type non-asphaltic base waterproof composition which 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 softener and 0.2-4 parts of a waterproof bridging agent, wherein one end in the structure of the waterproof bridging agent can be in reaction joining with groups like unsaturated C=C double bonds and carboxyl group (-cooh) in a non-asphaltic material, and the other end can be combined with hydrated calcium silicate or calcium aluminate which are produced in cement hydration process to form chemical bonds, and further can be subjected to chemical cross-linking reaction with concrete to set up a waterproof bridge, so that the non-asphaltic material can be tightly bonded with cement to form an integral body; besides, as related parts have chemical bond action, an irreversible cohesive action can be achieved after curing, the adhesive force between a waterproof glue and the base surface of cement can be increased, the bonding strength between the waterproof material and the base surface can be improved, and the weathering resistance of the waterproof material can be further improved.

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;...
