Problems solved by technology

[0003] The rubber runway is mainly laid by a number of prefabricated blocks of the rubber runway. The rubber runway can be laid on asphalt pavement or concrete pavement. Among them, the asphalt pavement has better drainage and lower cost, and is more commonly used. When laying the rubber runway, It is necessary to bond the prefabricated rubber runway blocks to the asphalt pavement with adhesive to fix the prefabricated rubber runway blocks on the asphalt pavement. Because athletes often run fast on the rubber runway, and most athletes wear sneakers with spikes, the rubber runway will It bears a large external force, and the direction of the external force is complex and diverse. Due to the lack of strength of the general adhesive, after a period of use, the rubber runway is prone to decline in stability such as displacement and peeling. Therefore, there are still improvements. space

Embodiment 1

[0052] An adhesive for bonding prefabricated rubber runways, including component A and component B stored independently, and component A includes the following components:

[0053] Polyester diol, polyether diol, chain extender, ethyl acetate, propylene glycol methyl ether acetate, catalyst.

[0054] B component is diisocyanate.

[0055] Wherein, polyester glycol is the composite of polyethylene adipate, polybutylene adipate, and the mass ratio of polyethylene adipate, polybutylene adipate is 3:2.

[0056] Wherein, polyether glycol is polyethylene glycol.

[0057] Wherein, the chain extender is 1,4 butanediol.

[0058] Among them, the catalyst is a compound of dibutyltin dilaurate, triethanolamine, bis(2-dimethylaminoethyl) ether, dibutyltin dilaurate, triethanolamine, bis(2-dimethylaminoethyl) ether The mass ratio is 3:5:1.

[0059] In Examples 1-5, see Table 2 for the specific input amount (unit: kg) of each component in component A.

Embodiment 1-5

[0066] In embodiment 1-5, the preparation method of A component is as follows:

[0067] Put polyester diol into a stirring tank, heat to 100°C, rotate at 30r / min, keep stirring, then put polyether diol, chain extender, ethyl acetate, propylene glycol methyl ether into polyester diol Acetate and catalyst, rotating at 60r / min, stirring for 5min, cooling to 40°C, subpackaging, pumping out the air in the package to obtain component A.

[0068] In embodiment 1-5, the preparation method of B component is as follows:

[0069] Put the diisocyanate into a stirred tank, heat to 100°C, rotate at 10r / min, stir for 10min, put in nitrogen protection, cool to 40°C, pack separately, and pump out the air in the package to obtain component B.

[0070] By mixing at 100°C, the moisture in each raw material is fully discharged, reducing the influence of moisture on the adhesive.

Embodiment 6

[0072] A prefabricated rubber runway bonding adhesive, compared with embodiment 3, the difference only lies in:

[0073] The mass ratio of dibutyltin dilaurate, triethanolamine and bis(2-dimethylaminoethyl) ether is 1:1:1.

Abstract

The invention relates to the field of adhesives, and particularly discloses an adhesive for bonding a prefabricated rubber runway. The adhesive for bonding the prefabricated rubber runway comprises a component A and a component B which are independently stored, and the component A comprises the following components in parts by mass: 100 parts of polyester glycol; 30 to 33 parts of polyether glycol; 10 to 12 parts of a chain extender; 20 to 21 parts of ethyl acetate; 4 to 5 parts of propylene glycol methyl ether acetate; 3 to 3.3 parts of a catalyst; the component B is diisocyanate; the catalyst is a compound of butyltin dilaurate, triethanolamine and bis (2-dimethylaminoethyl) ether; the ratio of the component A to the component B is 1: (0.1-0.12). The rubber runway has the advantage of improving the bonding stability of the rubber runway on the pavement.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an adhesive for bonding prefabricated rubber runways. Background technique [0002] With the development of society, people's demand for sports is increasing.
