Problems solved by technology

The traditional glue mainly has the following problems: 1. The operation time is as long as 20-60 minutes, the efficiency is low, and it is easy to cause secondary pollution and affect the bonding effect; 2. The thickness of the glue spraying or brushing is uneven, resulting in the sticking of the template cloth Not good, the concrete drainage holes are blocked, which directly leads to the uneven surface of the concrete components after forming, and numerous large and small trachomas, which increases the chance of microbial growth and shortens the service life of the concrete components; The surface of the component increases the risk of cracks and safety hazards

Embodiment 1

[0020] The spray glue contains acetone 25%, propane 20%, 2-methylpentane 15%, cyclohexane 5%, 3-methylpentane 5%, 2,3-dimethylbutane in mass percent 2.5%, 2,2-dimethylbutane 2.5%, hexane 0.5%, synthetic resin 24.5%.

Embodiment 2

[0022] The spray glue contains acetone 25%, propane 20%, 2-methylpentane 15%, cyclohexane 5%, 3-methylpentane 5%, 2,3-dimethylbutane in mass percent 2.5%, 2,2-dimethylbutane 2.5%, synthetic resin 25%.

[0023] The template cloth spray glue that prepares above-mentioned embodiment 1 and embodiment 2 needs to follow the following steps:

[0024] 1) Add and mix according to the proportion to prepare a liquid synthetic solution;

[0025] 2) Add the liquid synthetic solution into the reaction kettle and stir for 4-5 hours to make glue;

[0026] 3) Store the prepared glue in a special iron container and seal it with a tinplate valve;

[0027] 4) Filling with dimethyl ether propellant;

[0028] 5) Divided into hand-pressed small canned finished products.

Abstract

The invention discloses formwork cloth spray glue which is characterized by comprising, in weight percent, 25% of acetone, 20% of propane, 15% of 2-methylpentane, 5% of cyclohexane, 5% of 3-methylpentane, 2.5% of 2, 3-dimethylbutane, 2.5% of 2, 2-dimethylbutane, 0.1%-0.7% of hexane and 24.3-24.9% of synthetic resin. The formwork cloth spray glue has the advantages that the adhesive effect of formwork cloth and a formwork can be improved, the service life of a concrete component is prolonged, the formwork cloth is easily removed, and operating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing template cloth spray glue. Background technique [0002] At present, the market mainly uses all-purpose glue, embroidery spray glue, and glue brush for the joint of formwork and formwork cloth in the production of concrete components in the construction of bridges, subways, airports, docks, etc. The traditional glue mainly has the following problems: 1. The operation time is as long as 20-60 minutes, the efficiency is low, and it is easy to cause secondary pollution and affect the bonding effect; 2. The thickness of the glue spraying or brushing is uneven, resulting in the sticking of the template cloth Not good, the concrete drainage holes are blocked, which directly leads to the uneven surface of the concrete components after forming, and numerous large and small trachomas, which increases the chance of microbial growth and shortens the service...
