Abstract
The present invention provides the adhesive compound of a kind of cross-linkable solidifying, wherein, described adhesive compound includes epoxy resin and the flexible polymer that can solidify with cross linking of epoxy resin, the vitrification point of described flexible polymer is between 20 DEG C to 10 DEG C, and the molecular weight of described flexible polymer is not less than 10000.The present invention also provides for a kind of retroreflecting reflectorized material and the preparation method of a kind of retroreflecting reflectorized material.The viscosity of epoxy resin is preferable, and can have preferable flexibility with the flexible polymer of cross linking of epoxy resin solidification, the advantage that adhesive compound provided by the present invention combines the two, when the adhesive compound utilizing described cross-linkable solidifying prepares retroreflecting reflectorized material, only the less adhesive compound of need can be by glass microballoon together with bond matrix so that retroreflecting reflectorized material has the most flexible and preferable wearing comfort.
Description
Technical field
The present invention relates to retroreflecting reflectorized material field, in particular it relates to the adhesive composition of a kind of cross-linkable solidifying
Thing, the retroreflecting reflectorized material including the adhesive compound of this cross-linkable solidifying and the system of this retroreflecting reflectorized material
Preparation Method.
Background technology
Retroreflecting reflectorized material is typically by bead 300, the reflecting layer of shiny effect, passive base material
100 and the adhesive layer 200 that glass microballoon is bonded on base material 100 form, wherein, reflecting layer is arranged on bead 300
With on the surface of adhesive layer 200 laminating, the two constitutes the optical system of retroreflecting.As it is shown in figure 1, when Ray Of Light enters
When being mapped to described retroreflecting reflectorized material surface, can be through being equivalent to the refraction of glass microballoon of sphere lens and reflecting layer
Reflection, returns to light source direction.That is, when light is radiated on retroreflecting reflectorized material, reflection light can be pressed into penetrates light (light
Source) former input path reflect back.
When people are when carrying out nocturnalism, dress has the clothing of retroreflecting reflectorized material, it is possible to produce strong
Eye-catching effect, such that it is able to allow motor vehicle driver find in time and to take measures, plays the effect of safeguard protection for wearer.
Currently exist multiple retroreflecting reflectorized material, such as, US 4272564 discloses a kind of flexible reflection
Goods, this flexibility reflection goods include glass microballoon, the reflecting layer being formed on glass microballoon and the silk ribbon of support glass microballon.
Silk ribbon is flexible fabric, when utilizing binding agent to be sticked on silk ribbon by glass microballoon, generally requires substantial amounts of binding agent, reduces
The flexibility of the flexible reflection goods of final acquisition, thus reduce level of comfort and the aesthetic feeling of dress.
Therefore, the consumption how reducing binding agent while guaranteeing glass microballoon adhesion strength on base material becomes this
The technical problem that field is urgently to be resolved hurrily.
Summary of the invention
It is an object of the invention to provide the adhesive compound of a kind of cross-linkable solidifying, include the glue of this cross-linkable solidifying
The retroreflecting reflectorized material of adhesive composition and the preparation method of this retroreflecting reflectorized material.Utilize the less present invention
Glass microballoon can be reliably bonded on matrix by the adhesive compound provided.
To achieve these goals, as one aspect of the present invention, it is provided that the adhesive composition of a kind of cross-linkable solidifying
Thing, has flexibility after described adhesive compound crosslinking curing, and wherein, described adhesive compound includes epoxy resin and can
With cross linking of epoxy resin solidification flexible polymer, the vitrification point of described flexible polymer between-20 DEG C to-10 DEG C,
The molecular weight of described flexible polymer is not less than 10000.The adhesive compound of described cross-linkable solidifying also includes can be by ring
Epoxy resins and the co-curing agent of crosslinked polymer based on acrylate solidification.
As another aspect of the present invention, also disclose a kind of retroreflecting reflectorized material, the reflective material of this retroreflecting
Material includes matrix, retroreflecting element layer and the adhesive layer on the matrix that bondd by described retroreflecting element layer, its
In, described adhesive layer is that the adhesive compound crosslinking curing of above-mentioned cross-linkable solidifying provided by the present invention forms.Described
Matrix is selected from any one in mylar, nylon cloth and polyester-mixed cotton cloth.
As another aspect of the invention, disclose the preparation method of a kind of retroreflecting reflectorized material, wherein, described
Preparation method includes: provide reflecting element layer；Matrix is provided；By adhesive, described reflecting element layer is bonded in described matrix
On, to obtain retroreflecting reflectorized material, wherein, described adhesive is above-mentioned adhesive provided by the present invention.
The viscosity of epoxy resin is preferable, and can have the most soft with the flexible polymer of cross linking of epoxy resin solidification
Property, adhesive compound provided by the present invention combines the advantage of the two, is utilizing the adhesive group of described cross-linkable solidifying
When compound prepares retroreflecting reflectorized material, only need less adhesive compound can by glass microballoon with bond matrix one
Rise so that retroreflecting reflectorized material has the most flexible and preferable wearing comfort.
