Problems solved by technology

[0003] At present, the adhesives used for wet-laid self-adhesive waterproofing membranes are all cement slurry, which is a rigid material. When the base layer is deformed, the rigid adhesive is easy to crack and the base surface peels off, and the bonding is not firm, which affects the waterproofing membrane. waterproof effect

Embodiment 1

[0030] Add 100 parts of high-strength cement, 70 parts of quartz sand, 9 parts of active masterbatch, 15 parts of activated acrylic rubber powder, 6 parts of hydroxypropyl cellulose, 3 parts of water reducing agent, and 4 parts of early strength agent. Put it into the mixing tank for mixing and stirring, the mixing time is 40min-60min and then discharge the material for packaging. Mix the powder and water in a ratio of 10:4 at the construction site to obtain the adhesive for self-adhesive wet-laid waterproof membrane.

Embodiment 2

[0032] Add 100 parts of high-strength cement, 80 parts of quartz sand, 15 parts of active masterbatch, 17 parts of activated acrylic rubber powder, 8 parts of hydroxypropyl cellulose, water reducing agent: 3 parts, and early strength agent: 4 parts respectively. Put it into the mixing tank for mixing and stirring, the mixing time is 40min-60min and then discharge the material for packaging. Mix the powder and water in a ratio of 10:4 at the construction site to obtain the adhesive for self-adhesive wet-laid waterproof membrane.

Embodiment 3

Abstract

The invention provides an adhesive for a self-adhered wet paving waterproofing roll and a preparation method of the adhesive. The adhesive is prepared from the following raw materials in parts by weight: 100 parts of high-strength cement, 70-100 parts of quartz sand, 10-30 parts of an active master batch, 12-28 parts of activated acrylic rubber powder, 5-14 parts of hydroxy propyl cellulose, 2-6 parts of a water reducing agent and 2-6 parts of an early strength agent. The adhesive for the self-adhered wet paving waterproofing roll provided by the invention overcomes the defects that the traditional lean concrete grout is infirm in bonding and easy to crack and peel and the waterproofing effect of the waterproofing roll is influenced.

Description

technical field [0001] The invention belongs to the technical field of waterproof building materials, in particular to an adhesive used for self-adhesive wet-laid waterproof rolls and a preparation method. Background technique [0002] Since the self-adhesive waterproof membrane technology was introduced from Europe in 2009, it is a new technology product jointly developed by experts and professors from domestic universities and scientific research institutes. It is a "special function" waterproof material that replaces various building waterproofing. The overall waterproof layer that permeates to the base layer forever after the construction reacts chemically has been used in Europe for more than 20 years, and the effect is very good. [0003] At present, the adhesives used for wet-laid self-adhesive waterproofing membranes are all cement slurry, which is a rigid material. When the base layer is deformed, the rigid adhesive is easy to crack and the base surface peels off, a...
