Description
Technical Field
The application belongs to the technical field of polyurethane materials, and particularly relates to color polyurethane glue, a preparation method thereof and application thereof in yellowing-resistant EPDM sports fields.
Background
The polyurethane plastic track has the characteristics of good flatness, excellent anti-skid and wear-resistant properties, proper hardness and elasticity and stable physical properties, is used as a sports field, is beneficial to the playing of the athletic level of athletes, can effectively improve the athletic performance and reduce the health injury of the athletes caused by the sports. The polyurethane plastic track is the internationally recognized optimal all-weather outdoor sports ground floor material.
The polyurethane plastic track has two large series of models, namely breathable type and hybrid type. The breathable EPDM sports field is directly paved after single-component polyurethane glue and EPDM rubber particles are mixed according to a certain proportion, has the advantages of long service life, moderate comprehensive performance, quick construction, low price and the like, and is not easy to generate phenomena of foaming, bulging and the like. Meanwhile, the breathable EPDM sports field can be matched with various colors, and the field is attractive and elegant, so that the breathable EPDM sports field has absolute advantages in plastic paving proportion of primary, middle and primary schools and various sports fields, and is popular.
Considering the factors of cost, performance, environmental protection, health and the like, the preparation of the single-component polyurethane glue used in most EPDM sports fields at present mainly comprises the steps of matching polyether polyol with various aromatic isocyanates, and the prepared single-component polyurethane glue is usually colorless or pale yellow transparent liquid. However, the single-component polyurethane glue is affected by light, heat, oxygen, water and other environmental conditions during use, so that the EPDM sports ground turns yellow under sunlight. In order to delay or prevent yellowing of EPDM sports fields, the methods currently in common use include the addition of uv absorbers to the glue or the use of aliphatic isocyanates instead of aromatic isocyanates. The ultraviolet absorber is a light stabilizer, can absorb ultraviolet light and release light energy in a form of heat energy, so that the photo-oxidative aging effect of ultraviolet light on a matrix polyurethane material is effectively reduced, but the ultraviolet absorber has unavoidable defects in the use of an EPDM sports ground, for example, because the organic ultraviolet absorber is easy to decompose and volatilize, the yellowing resistance of polyurethane glue prepared by using the ultraviolet absorber cannot be kept for a long time generally, and the prepared breathable runway can gradually yellow along with the consumption of the organic ultraviolet absorber after solar irradiation for a few days. In addition, aliphatic isocyanates are generally several times more expensive than aromatic isocyanates, with higher costs; and compared with aromatic isocyanate, the prepared glue has relatively poor performance and slower curing speed, and is unfavorable for construction operation.
Therefore, the application provides the color polyurethane glue which is applied to the EPDM sports field, and the technical problems are effectively solved.
