Abstract
The invention provides a retrodirective reflection vulcanite product, which is provided with a retrodirective reflector plate connected with the product. The retrodirective reflector plate comprises a plurality of retrodirective reflection components embedded in a polyurethane bonding layer at least partially. The polyurethane bonding layer comprises the reaction products of at least one diisocyanate, at least one polyisocyanate, at least one polyhydric alcohol, at least one unsaturated polyhydric alcohol and at least one chain extension agent. The invention further provides a method for preparing the retrodirective reflection vulcanite product.
Description
Technical field
The present invention relates to the retrodirective reflection vulcanized rubber article, for example the retrodirective reflection tire.The present invention also relates to prepare the method for this goods with Rectroreflective sheet.
Background technology
Retrodirective reflection is a kind of phenomenon that successfully has been used to prepare with security-related goods.Retrodirective reflection can be defined as a kind of phenomenon, and wherein most of luminous radiation is back on the direction of its generation.This can realize that spherical reflector can be bead or glass microsphere by using spherical reflector, and it is coated with reflecting material to small part.
In these goods, having benefited from using the goods of retrodirective reflection is rubber, for example tire.Bicycle tyre and motorcycle tyre are extremely to need reflex reflection performance example, because be a special safety problem for the cyclist in night visibility.Usually bicycle is equipped with reflector at its support and/or tyre rim, but tire itself does not have reflectivity.Make tire have reflectivity, so usually can be by the installation reflector or with tire and the compound reflectivity that obtains of reflective elements in manufacture process.But when reflector is installed on the tire,, and owing to be subjected to the restriction of its overlay area and the reflector of installation can not provide good visibility owing to the continuous motion in the use makes the reflector of installing be damaged and falls down.The retrodirective reflection pearl is mixed the problem that produces with tire be that the brightness of this reflector is relatively poor usually.The reflective tape that will have a retroreflectiveness is incorporated into rubber for example in the tire, can make rubber in use keep continual and steady retrodirective reflection performance.
Summary of the invention
The retrodirective reflection vulcanized rubber article is provided, and described goods have coupled reflective tape.In some embodiments, vulcanized rubber article contains the retrodirective reflection reflective tape of vulcanized rubber and the bonding layer of polyurethane.Described adhesive layer has first surface and second surface, and a plurality of reflective elements that are partly embedded in the first surface are arranged on the first surface; The second surface of adhesive layer can be directly and the vulcanized rubber part bonding.Reflective elements can be the microballoon that partly applies with metal.Polyurethane binder contains the product of at least a vulcabond, at least a polyisocyanates, at least a polyalcohol, at least a unsaturated polyol and at least a chain elongation agent.Polyurethane binder also can contain degree of functionality greater than 2 polyalcohol.In some embodiments, polyurethane binder also contains silane coupler.
The method for preparing the retrodirective reflection vulcanized rubber article is provided.In some embodiments, the method for preparing vulcanized rubber article comprises provides the retrodirective reflection piece element that contains the bonding layer of polyurethane, second surface and a plurality of reflective elements that the bonding layer of described polyurethane has the unsaturated position that is used for co-vulcanization are partly embedded in first surface.The second surface of the bonding layer of polyurethane is contacted with unvulcanized rubber material; Under heating and pressure, vulcanize unvulcanized elastomeric material and make that the second surface of adhesive layer of retrodirective reflection piece element is mutually bonding with vulcanized rubber material.In some embodiments, the second surface and the contacted step of unvulcanized rubber material of the bonding layer of polyurethane comprise: retrodirective reflection reflective tape and half finished rubber are placed in the mould, and heating and pressurization.Polyurethane binder comprises the product of at least a vulcabond, at least a polyisocyanates, at least a polyalcohol, at least a unsaturated polyol and at least a chain elongation agent.In some embodiments, polyurethane binder is the product of two parts of reactant mixtures, and wherein first part comprises the polyurethane prepolymer that contains at least a vulcabond, at least a polyisocyanates, at least a polyalcohol and at least a unsaturated polyol; Second part comprises at least a chain elongation agent.
Description of drawings
Fig. 1 has shown the cross sectional representation of the Rectroreflective sheet of one section described co-vulcanization of the present invention.
Fig. 2 has shown the cross sectional representation of the Rectroreflective sheet of one section described co-vulcanization of the present invention.
Fig. 3 has shown the cross sectional representation of one section described vulcanized rubber article of the present invention.
The specific embodiment
The retrodirective reflection vulcanized rubber article is provided, and described goods have coupled retrodirective reflection reflective tape.The retrodirective reflection reflective tape prepares by reflective elements and polyurethane binder, and the retrodirective reflection reflective tape is used for forming rubber with the half finished rubber co-vulcanization.In some embodiments, rubber is a tire, for example bicycle tyre.
The retrodirective reflection reflective tape contains a plurality of reflective elements that are partly embedded at least in polyurethane binder.The product of preferably at least a vulcabond of polyurethane binder, at least a polyisocyanates, at least a polyalcohol, at least a unsaturated polyol and at least a chain elongation agent.
