What is asphalt glue and what is asphalt

Asphalt adhesive is a mineral adhesive based on petroleum asphalt, in order to improve the heat resistance of asphalt and reduce the low-temperature brittleness of asphalt layer, a liquid made by adding filler to the asphalt material for modification.

Type. There are three types: hot melt type, solvent type and emulsion type.

The hot-melt type is obtained by melting asphalt with coal tar, recycled rubber, waste PVC plastic, etc.

The solvent type is obtained by adding epoxy resin, recycled rubber, and asbestos powder to the solvent of asphalt.

The emulsion type is obtained by adding emulsifier and dispersant to asphalt to form a dispersed and stable emulsion.

Summary. Modified asphalt and galvanized sheet can be bonded with HY-106AB glue or HY-127 glue.

Summary. Bitumen is a black or brown gelatinous substance that is commonly used in road construction, roof waterproofing, industrial anti-corrosion, waterway construction, and other fields. It is a mixture extracted from by-products of petroleum processing, mainly composed of hydrocarbons, including many different kinds of chemicals.

At higher temperatures, bitumen can become soft and sticky for easier coating and bonding, while at lower temperatures it becomes hard and brittle. Due to its good waterproofing, bonding and durability properties, asphalt is widely used in the construction and industrial fields.

Due to its waterproofing, adhesive and durability properties, asphalt is widely used in the construction and industrial sectors.

In addition to the construction and industrial sectors, asphalt is also used in the manufacture of asphalt mixtures, a material used on roads and other roads for paving and repairing road surfaces. Asphalt mixtures are usually made from a mixture of asphalt and mineral aggregates, which can be stones, sand, or gravel, etc., to improve the durability and compressive strength of the pavement. Bitumen can also be used as a chemical raw material to make products such as flexible pipes, sealing materials, asphalt paper, etc.

In the construction of the waterway, asphalt is used to protect the anti-corrosion and anti-corrosion of the cement mixed acacia Zaopei concrete wharf to prolong the service life of the wharf. In addition, asphalt rock decay is also used for the preservation of works of art and cultural heritage, for example for the restoration and protection of the roofs and walls of ancient buildings.

Bitumen is a complex black-brown mixture of hydrocarbons of different molecular weights and their non-metallic derivatives.

Bitumen is a kind of high-viscosity organic liquid, mostly in the form of liquid or semi-solid petroleum, with a black surface and soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic cementitious material that is waterproof, moisture-proof and anti-corrosion.

Asphalt can be divided into three main types: coal coke asphalt, petroleum asphalt and natural asphalt: among them, coal coke asphalt is a by-product of coking. Petroleum bitumen is the residue after distillation.

Natural bitumen is stored underground, and some form layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries, as well as paving roads.

Asphalt composition

In recent years, the most commonly used method is to separate bitumen into four components: saturated, aromatic, colloidal and asphaltene, according to L.W. Colbet's method. There is a certain regularity between the content of each component in asphalt and the technical properties of asphalt.

According to the colloidal structure, with the decrease of the saturation and aromatic content of the dispersed medium, the content of the protective substance colloidal and the dispersed phase asphaltene increased, and the asphalt changed from sol structure to sol-gel structure and then gel structure. The penetration degree in the asphalt technical index decreases and the softening point increases. When the proportion of each component in the asphalt is coordinated, the best ductility can be obtained.

Bitumen is a highly viscous organic cementitious material.

It is a high-viscosity organic cementitious material, which is black or brownish-black gelatinous, mainly composed of hydrocarbons, non-metallic derivatives and other substances. This material basically exists in the form of asphalt or tar, which is generally used in paving projects and has a good anti-corrosion effect. It needs to be used mainly in the season, and if it is winter, you need to pay attention to low temperature weather, because it is easy to brittle.

If it is summer, it is very easy to be softened, but the viscosity is improved. It is a kind of waterproof and anti-corrosion material widely used in civil engineering, which is mainly used in roofing, ground and other structural waterproofing projects, and is also used to prevent corrosion of wood and steel materials. At the same time, it can also be used in road engineering, as a pavement structure cement material, and can be used in combination with other mineral materials.

Uses of bitumen

For asphalt pavement, its strength, stiffness will be reduced due to the increase of temperature, in order to prevent asphalt pavement from causing problems such as skidding, rutting and congestion under the action of repeated driving loads, in the high temperature season, asphalt pavement needs to have high temperature stability. As the temperature decreases, the stiffness of the asphalt pavement increases and the expansion decreases.

Part of the stress is relaxed too late due to the action of external loads, and the stress gradually accumulates, and when the accumulated stress exceeds the tensile strength of the material, cracks will appear and damage the road surface. Fatigue resistance refers to the ability of asphalt pavement to resist damage, because asphalt pavement will be subjected to repeated wheel loads during use, and the structural strength of the pavement will gradually decrease with the long-term overlap of stress and strain.
