Problems solved by technology

[0005] (3) Asphalt mastic; this product is a coagulation product mixed with petrochemical asphalt after hot-melting with fibers, gravel, and salt. It has the characteristics of long service life, relatively environmental protection, and good weather resistance, but the construction is troublesome , there is a pungent smell when hot-melted, a certain amount of phenol volatilizes, and the cost is high

Embodiment Construction

[0015] The technical solutions of the present invention are described below to facilitate the understanding of those skilled in the art.

[0016] Such as figure 1 Said, the present invention provides a kind of production technology of resinized waterproof caulking material, comprises the following steps:

[0017] (1) add catalyst and formaldehyde after asphalt, waste plastics, waste rubber are mixed, and stir;

[0018] (2) Heating to 160-170°C through a heating furnace, and carrying out negative 2PA stripping through a vacuum pump at the same time;

[0019] (3) After adding solid material, urea, and directional solidification inhibitor to solidify, stir again, during which the solidification time is 2-3 hours;

[0020] (4) shearing by a shearing machine, shearing into a three-dimensional network structure, then cooling and escorting;

[0021] (5) Finally package the finished product.

[0022] Working principle: Phenol in asphalt can react with environmentally friendly form...

Abstract

The invention discloses a production technology of a resinified waterproof joint filling material. Negative pressure stripping is carried out on all raw materials during hot blending, therefore the product has few volatile matters, and naturally no smell is generated at high temperature. Adopted solid powder is adsorption skeleton materials of various structural shapes, a three-dimensional network structure is formed after shearing, the strength and toughness of the product are improved, also effective small molecular colloids in organic materials are locked, the ageing resistance is improved, and by adding waste plastic and waste rubber powder, the elasticity and softening point of the material are enhanced. The brittle point is lowered, and at the same time a crazing automatic repair function is increased.

Description

technical field [0001] The invention belongs to the field of waterproof caulking materials, in particular to a production process of resinized waterproof caulking materials. Background technique [0002] At present, the waterproof joint filling materials used in buildings, roads and bridges, and water conservancy in my country are nothing less than the following three types; [0003] (1) Polyurethane series waterproof materials. This type of product is expensive and environmentally friendly, but it is easy to age and the service life is not very ideal. [0004] (2) Ointment: The production and application process of this type of product is not environmentally friendly, and has toxic and side effects. The construction needs to be heated and scraped, and the solidification is slow, the service life is relatively long, and the material cost is low. There is secondary environmental pollution. [0005] (3) Asphalt mastic; this product is a coagulation product mixed with petroc...
