Problems solved by technology

With the continuous improvement of people's living standards, the requirements for the living environment are getting higher and higher, especially in the aspect of house decoration, which is becoming more and more high-end. The most complicated construction, the longest construction period, and the highest construction requirements are toilets and shower rooms. Waiting for the facilities, the traditional waterproofing and tile sticking construction often takes 15 days or even longer, so it is becoming more important and urgent to find a waterproof product that shortens the construction period and simplifies the construction steps
In this regard, we aim to develop a tile adhesive with adjustable drying time for bonding and waterproofing, so as to solve the problem of long construction period for building waterproofing

Abstract

The invention discloses an organic silicon rubber waterproof adhesive and a preparation method thereof. The preparation method comprises the steps of: firstly, respectively feeding 20-40 parts by weight of hydroxyl-terminated polysiloxane, 4-7 parts by weight of a reinforcing agent, 41-60 parts of inorganic filler and 2-5 parts of inorganic adsorbent into a stirrer, mixing, and continuously discharging the mixed adhesive material; continuously feeding the mixed adhesive material into a material tank under a reduced pressure state by a pump and continuously degassing in the material tank; continuously feeding the degassed adhesive material into a static mixer, and meanwhile continuously feeding a mixture of 1-3 parts of a crosslinking agent and 0.2-0.8 part of a catalyst into the static mixer by a horizontal closed type continuous kneader; continuously feeding the statically-mixed adhesive material into a double-screw mixing extruder and meanwhile, continuously refilling 0.2-0.8 part of a silane coupling agent and 0.5-3 parts of a curing catalyst through a dropwise filling hole with pressure in the double-screw mixing extruder; mixing the adhesive material in the double-screw mixing extruder, continuously feeding the adhesive material into the mixer for degasing, and finally packaging.

Description

technical field [0001] The invention relates to an adhesive, in particular to a silicone rubber waterproof adhesive. The invention also relates to a preparation method of the silicone rubber waterproof adhesive. Background technique [0002] With the continuous development of our country's economy, there are more and more infrastructure constructions, and the cost of construction construction also rises. Residential construction occupies a large proportion of infrastructure construction. With the continuous improvement of people's living standards, the requirements for the living environment are getting higher and higher, especially in the aspect of house decoration, which is becoming more and more high-end. The most complicated construction, the longest construction period, and the highest construction requirements are toilets and shower rooms. Waiting for the facilities, the traditional waterproofing and tile sticking construction often takes 15 days or even longer, so it...
