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

[0010] 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 paste with a colloid mill, add 0.3 parts of aluminum zirconate bridging agent, and continue stirring 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

[0012] 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 are mixed, ground to a paste with a colloid mill, and 0.5 parts of stearic acid rare earth compound are added, and the stirring is continued to make The materials are mixed 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

[0014] 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 to a paste with a colloid mill, add 3 parts of wood Add plain bridging agent, continue to stir to mix the materials evenly, and 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 an application of a waterproof bridging agent in a non-asphalt base waterproof material. The waterproof bridging agent accounts for 0.3-3% of weight of sticky substances in the non-asphalt base waterproof material. One end of a structure of the waterproof bridging agent can be connected with groups such as unsaturated C=C double bonds, carboxyl (-COOH) and the like in the non-asphalt base waterproof material; the other end of the structure can be combined with hydrated calcium silicate or calcium aluminate generated in a cement hydration process to form a chemical bond; the chemical bond and the concrete generate chemical cross-linking reaction to build a bridge for tightly connecting the non-asphalt base material and cement into an integer; and chemical bond actions exist in relevant parts and make reversible bonding effects after curing, thereby improving adhesive force between waterproof glue and a cement base surface, improving adhesion strength between the waterproof material and the base material and improving weather resistance of the waterproof material.

Description

technical field [0001] The invention relates to the application of a waterproof bridging agent in non-bitumen-based waterproof materials. Background technique [0002] 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 Golden Umbrella Waterproof Decoration Co., Ltd. discloses a waterproof coiled material that can chemically cross-link and physically bond with cement concrete. The waterproof glue is to add a functional additive capable of chemical cross-linking reaction with cement concrete into the modified asphalt, and the functional additive is polymethylethoxysilane or sodium polynaphthaldehyde sulfonate. Since the active gr...
