Embodiment 1

[0010] The invention is an environment-friendly concrete modifier, which is made of the following raw materials in parts by weight:

[0011] Acrylate functional compound 3.2 parts, polycarbonate 1.8 parts, organoamine lignin 2.8 parts, alkali lignin 3.2 parts, benzoic acid 1.5 parts, carrageenan 1.3 parts and borax 3.2 parts.

Embodiment 2

[0013] The invention is an environment-friendly concrete modifier, which is made of the following raw materials in parts by weight:

[0014] Acrylate functional compound 2.5 parts, polycarbonate 1.5 parts, organoamine lignin 2.5 parts, alkali lignin 2.5 parts, benzoic acid 0.8 part, carrageenan 0.7 part and borax 2 parts.

Embodiment 3

[0016] The invention is an environment-friendly concrete modifier, which is made of the following raw materials in parts by weight:

[0017] Acrylate functional compound 3.8 parts, polycarbonate 2.8 parts, organoamine lignin 3.2 parts, alkali lignin 3.3 parts, benzoic acid 1.7 parts, carrageenan 2.5 parts and borax 4 parts.

[0018] Compared with the existing modifiers, the present invention adds acrylate functional compounds, benzoic acid and carrageenan in the production process of asphalt mixture, and forms a lubricating polymer chain structure inside the cement after adding, greatly reducing the The mixing and rolling temperature of the mixture saves energy consumption; the compaction performance is good, and the number of rolling is reduced; the road surface is of good quality, with good high-temperature anti-rutting ability, water damage resistance and anti-aging ability; low raw material cost, Low smoke and gas emissions, very environmentally friendly; wide range of app...

Abstract

The invention discloses an environment-friendly type concrete modifier, which is prepared by the following raw materials by weight: 2.5-3.8 parts of acrylic acid ester functional compound, 1.5-2.8 parts of polycarbonate, 2.5-3.2 parts of organic amine lignin; 2.5-3.3 parts of alkali lignin, 0.8-1.7 parts of benzenecarboxylic acid, 0.7-2.5 parts of carrageenan, and 2-4 parts of borax. Compared with the prior modifier, acrylic acid ester functional compound, benzenecarboxylic acid and carrageenan are added in an asphalt mixture production process, so as that a lubrication high-molecular chain-shaped structure is formed in a cementation material after addition, mixing and grinding temperature of a mixture is greatly reduced, and energy consumption is saved; pavement has good quality, and has a good high temperature rut resistant capability, a water damage resistant capability and an ageing resistance; and the raw materials have advantages of low cost, small smog and gas discharge amount, and environmental protection.

Description

technical field [0001] The invention relates to an environment-friendly concrete modifier, which belongs to the field of building materials. Background technique [0002] In modern society, due to the sharp increase in traffic flow and driving frequency, the axle load of freight vehicles continues to increase, and one-way driving in separate lanes is generally implemented. The ability to resist cracking at low temperature; improve wear resistance and prolong service life. The existing petroleum asphalt is no longer suitable for changes in the road surface environment, so people have developed modified road asphalt. This modified asphalt has better performance, but the price is relatively high, and it is not suitable for large-scale popularization and application. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an environment-friendly concrete modifier with low raw ma...
