Embodiment 1

[0091] (1) Preparation of amino components:

[0092] The amine-based component consists of the following raw materials:

[0093]

[0094] The production method of the modified amino compound is as follows: melt 30 parts by weight of p-phenylenediamine at 135°C, then add 90 parts by weight of glacial acetic acid and 1 part by weight of phosphoric acid to p-phenylenediamine dropwise at 150°C within 50 minutes The formed mixture was heated to reflux after the dropwise addition and the reaction temperature was controlled. After the initial reaction, the water generated by the reaction was distilled off and then heated to reflux for reaction. After the reaction is finished, the reactant is removed, followed by grinding, washing, suction filtration and drying to obtain the modified amino compound.

[0095]The production method of the amine-based component is as follows: Stir the modified amino compound, titanium dioxide, tourmaline powder, silicon dioxide, matting powder, pigme...

Abstract

The invention discloses a modified polyurea composition for road surface cooling regulation and control as well as a production method and application of the modified polyurea composition. The modified polyurea composition comprises an amino component and an isocyanate component, wherein the amino component comprises a modified amino compound, titanium dioxide, tourmaline powder, silicon dioxide, matting powder, pigment and a wetting dispersant, and the isocyanate component comprises a modified isocyanate compound. A material obtained after the reaction of the modified polyurea composition has excellent low-temperature bending performance.

Description

technical field [0001] The invention relates to a pavement cooling modified polyurea composition, a production method and application thereof. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is a kind of advanced pavement widely used in road construction. However, asphalt is easy to absorb heat, and it is easy to cause pavement diseases and aggravate the heat island effect at high temperature. Laying other film layers on asphalt pavement has become a more commonly used method at present. [0003] CN103214921A discloses a reflective thermal insulation spray polyurea elastic material. The polyurea elastic material is composed of A and B components. A component is composed of a semi-...
