Embodiment 1

[0046] In the embodiments of the present application, the weight ratio of each component of the reactive adhesive is as follows:

[0047] 90#asphalt 38%

[0048] 10#asphalt 2%

[0049] Rubber oil 12%

[0050] SBS 4%

[0051] PE 2%

[0052] Styrene butadiene rubber 5%

[0053] Petroleum resin 0.5%

[0054] Asphalt modifier 0.5%

[0055] Stone powder 20%

[0056] Silica 3%;

[0057] Silane coupling agent 5%;

[0058] Wherein, when the ratio is used, the sum of the percentages of the content of each component in the composition is equal to 100%.

[0059] In this application, 90# asphalt in the reactive adhesive is mainly used as the main material of the reactive adhesive, which can endow the reactive adhesive with good anti-aging properties and good adhesion to the concrete base.

[0060] Rubber oil has the functions of adjusting the viscosity of the rubber, improving the processing performance of the rubber, and providing the anti-aging performance and flexibility of the rubber.

[0061] The role o...

Embodiment 3

[0082] In the embodiments of the present application, the components of the reactive adhesive also include rubber powder, and the weight ratio of each component is as follows:

[0083] 90# Asphalt 35%

[0084] 10#asphalt 3%

[0085] Rubber oil 7%

[0086] SBS 6%

[0087] PE 5%

[0088] SBR 2%

[0089] Petroleum resin 4%

[0090] Rubber powder 8%

[0091] Asphalt modifier 1%

[0092] Stone powder 21%

[0093] Silica 3%;

[0094] Silane coupling agent 5%;

[0095] Wherein, when the ratio is used, the sum of the percentages of the content of each component in the composition is equal to 100%.

Embodiment 4

[0097] The embodiment of the present application also provides a preparation method of the reactive adhesive, which is used to prepare the reactive adhesive described in the foregoing embodiment 1. According to the components provided in the foregoing embodiment 1, the preparation method is as follows:

[0098] 1. Weigh each component raw material according to the weight percentage ratio.

[0099] 2. Add 90# asphalt, 10# asphalt and rubber oil into the reaction vessel and heat up to 185°C.

[0100] 3. Add SBS and PE into the reaction vessel and keep the temperature at 185°C for 1 hour.

[0101] 4. When the viscosity coefficient of the mixture in the reaction vessel reaches a preset threshold, add styrene butadiene rubber, petroleum resin, silica and silane coupling agent into the reaction vessel for modification, and let it stand for 1 hour.

[0102] Setting the preset threshold is mainly to make the viscosity of the mixture in the reactor meet the requirements. The preset threshold ca...

Abstract

The present disclosure relates to a reaction adhesive and a preparation method thereof, the reaction adhesive comprises 90# asphalt, 10# asphalt, rubber oil, SBS, PE, styrene butadiene rubber, petroleum resin, an asphalt modifier, a silane coupling agent, stone powder and silica. By adding of the silane coupling agent and the silica, the asphalt is modified, and by modifying of the characteristicsof the asphalt, when the reaction adhesive is applied, lean concrete grout is first used for paving, and then the reaction adhesive is laid on the surface of cement. During the solidification of thecement, hydration heat is formed, free silica molecules are released, the free silica molecules can be combined with active silica molecules released in the reaction adhesive, chemical bonds are formed in capillary pores of a cement base layer for crosslinking, and the bond strength is improved.

Description

Technical field [0001] The present disclosure relates to the technical field of building materials, in particular to a reactive adhesive and a preparation method thereof. Background technique [0002] At present, many housing constructions in my country, such as concrete buildings such as roof exterior walls, tunnels, basements, toilets, etc., will have various cracks, and there are different degrees of water leakage. The causes of house leakage are more complex, involving factors such as design, materials, construction, and management. [0003] Asphalt used in waterproofing projects has the advantages of readily available raw materials and low price. It is the most widely used waterproof material in waterproof and seepage-proof projects at home and abroad. However, due to its own hot dripping and cold brittleness, poor weather resistance, as well as the commonly used on-site cooking and hot construction methods, it will produce air pollution, prone to fire and scald accidents, lo...
