Problems solved by technology

Of course, the modified two-component epoxy resin adhesive also has certain defects. For example, epoxy resin generally needs to be cured above 10°C. If the temperature is too low, the curing time will be too long; Susceptible to brittle fracture after stress

Embodiment 1

[0012] The ambient temperature of the pavement construction is 30°C.

[0013] 1) Preparation of component A: add 100 parts of bisphenol A epoxy resin E-44, 10 parts of reactive diluent, and 30 parts of reactive toughening agent, all of which are calculated by weight, into a vacuum mixer, and slowly increase the speed of stirring To 750 rpm, stirred for 30 minutes, and discharged to obtain component A;

[0014] Preparation of component B: Add 80 parts of polyamide resin 650, 20 parts of epoxy resin curing agent, 10 parts of curing accelerator, and 1.5 parts of silane coupling agent. The above components are all calculated by weight, add them to the vacuum mixer, and slowly increase the speed Stir to 750 rpm, stir for 30 minutes, and discharge to obtain component B. When the pavement surface bonding material is used, the ratio of components A and B is: component A: component B = 1:1.

Embodiment 2

[0016] The ambient temperature of the pavement construction is 25°C.

[0017] 1) Preparation of component A: add 100 parts of bisphenol A epoxy resin E-44, 15 parts of reactive diluent, and 20 parts of reactive toughening agent, all of which are calculated by weight, into a vacuum mixer, and slowly increase the speed of stirring To 750 rpm, stirred for 30 minutes, and discharged to obtain component A;

[0018] Preparation of component B: Add 90 parts of polyamide resin 650, 20 parts of epoxy resin curing agent, 15 parts of curing accelerator, and 1.0 part of silane coupling agent. The above components are all calculated by weight, add them to the vacuum mixer, and slowly speed up Stir to 750 rpm, stir for 30 minutes, and discharge to obtain component B. The ratio of components A and B when the pavement surface bonding material is used is: component A: component B = 1:2.5

Embodiment 3

[0020] The ambient temperature of the pavement construction is 15°C.

[0021] 1) Preparation of component A: Add 100 parts of bisphenol A epoxy resin E-44, 20 parts of reactive diluent, and 10 parts of reactive toughening agent. The above components are all calculated by weight, add them to a vacuum mixer, and slowly increase the speed of stirring To 750 rpm, stirred for 30 minutes, and discharged to obtain component A;

[0022] Preparation of component B: 85 parts of polyamide resin 650, 30 parts of epoxy resin curing agent, 20 parts of curing accelerator, 3.0 parts of silane coupling agent, 5 parts of hyperbranched polymer, the above components are all calculated by weight, Add it into a vacuum mixer, slowly increase the speed of stirring to 750 rpm, stir for 30 minutes, and discharge to obtain component B. The ratio of components A and B when the pavement surface bonding material is used is: component A: component B = 1:3.5

Abstract

The invention provides a preparation method of a colored skid-free road surface layer binding material. The binding material is composed of two components. The preparation method comprises the following steps: (1) preparation of component A: treating 100 parts of bisphenol A epoxy resin E-44 or bisphenol A epoxy resin E-51, 0-20 parts of reactive diluent and 0-30 parts of active toughener in a vacuum mixer to obtain the component A; and (2) preparation of component B: treating 80-100 parts of polyamide resin 650 or polyamide resin 651, 0-35 parts of epoxy resin curing agent, 0-20 parts of curing accelerator, 0-3 parts of silane coupling agent and 0-200 parts of filler in a vacuum mixer to obtain the component B. When in use, the proportion of the component A to the component B is 1:(0.5-4). The method provided by the invention is simple to operate and easy for construction, and does not add any inert component or use any organic solvent in the preparation process. The colored skid-free road surface layer binding material has the advantages of high binding strength, high economical efficiency and environment friendliness.

Description

technical field [0001] The invention relates to a preparation method of a colored non-slip pavement surface layer adhesive material, which belongs to the fields of adhesives and polymer chemistry. Background technique [0002] With the rapid development of my country's economy, my country's road traffic infrastructure construction has also achieved unprecedented results. By the end of 2010, the total mileage of my country's highways had reached 3.984 million kilometers, of which 74,000 kilometers were highways, ranking second in the world after the United States. However, with the improvement of highway mileage and the increase of traffic flow, the traffic safety problems of high-grade highways are becoming increasingly prominent. From 2001 to 2003, the number of traffic accident deaths in my country exceeded 100,000 for three consecutive years, accounting for more than 15% of the world's traffic accident deaths. Faced with such a severe traffic safety situation, at the be...
