Embodiment
In order to make the technical problems to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model embodiment provides, a kind of VELCRO 1, comprise hook face 11 and the back side 12, the described back side 12 comprises substrate layer 121 and the first adhesive-layer 124, wherein, described substrate layer 121 comprises a uneven surface 1211 be oppositely arranged with described hook face 11, and described first adhesive-layer 124 adhering junction is on described uneven surface 1211.
Due in described VELCRO 1, the substrate layer 121 at the described back side 12 is generally smooth surface, and therefore, directly when described substrate layer 121 surface arranges described first adhesive-layer 124, its adhesiving effect is poor.For this reason, need the roughness improving the described back side 12, thus improve the bonding degree of the binding agent connecting described VELCRO 1 and carrier.In view of this, the utility model embodiment on the one hand on described substrate layer 121, the surface relative with described hook face 1 be provided with uneven surface 1211, improves the cohesive force between described first adhesive-layer 124 and described substrate layer 121.
In order to increase the bonding force of the cohesive force between the first adhesive-layer 124 and described substrate layer 121 further, as preferred embodiment, the described back side 12 of described VELCRO 1 is also included in the second adhesive-layer 122 and back of the body cloth 123 that are cascading between described substrate layer 121 and described first adhesive-layer 124, wherein, described back of the body cloth 123 is connected on described uneven surface 1211 by described second adhesive-layer 122, described first adhesive-layer 124 adhering junction on described back of the body cloth 123, as shown in Figure 2.Described back of the body cloth 123 has larger frictional coefficient, can form firm engagement with described first adhesive-layer 124, described second adhesive-layer 122, and then improves described VELCRO 1 and be carried on firmness on carrier.
In the utility model embodiment, the setting of described first adhesive-layer 124, adheres to carrier during for described VELCRO 1 being prepared into VELCRO workpiece.As preferred embodiment, described first adhesive-layer 124 is the one in TPU, EVA, PET, PO, PA, PUR.Further, described first adhesive-layer 124 is preferably environmental protection and cheap TUP.
In the utility model embodiment, as preferred embodiment, described second adhesive-layer 122 is PUR layer.This preferred PUR layer, its viscosity is strong, can by described back of the body cloth 123 secure adhesion on described substrate layer 121.
In the utility model embodiment, described back of the body cloth 123 is for improving the functional layer of the back side 12 roughness described in described VELCRO 1.As preferred embodiment, described back of the body cloth 123 is textile layer or nonwoven layer.This preferably carries on the back cloth 123, and not only material is easy to get, and soft comfortable, be applicable to being applicable to require higher VELCRO product to comfort level, thus the use field of VELCRO described in easily extensible.As concrete preferred embodiment, described back of the body cloth 123 includes but not limited to the one in the coarse textiless such as nylon layer of cloth, terylene layer of cloth, bright and beautiful ammonia layer of cloth.
As a concrete preferred embodiment, in described VELCRO 1, described second adhesive-layer 122 is PUR layer, and described back of the body cloth 123 is nylon layer of cloth, and described first adhesive-layer 124 is TPU layer.
The described VELCRO 1 obtained by described second adhesive-layer 122 and the adhering junction of described back of the body cloth 123 can possess superpower viscosifying power.As, when using TPU as described second adhesive-layer 122, when described back of the body cloth 123 is nylon layer of cloth, cohesive strength > 1850N/M; When described back of the body cloth 123 is nonwoven layer, cohesive strength > 2000N/M.
The VELCRO that the utility model embodiment provides, on the basis of original VELCRO material, make improvements, uneven surface is set in the one side relative with hook face, thus improve the roughness at the VELCRO back side, by described first adhesive-layer close adhesion on described substrate layer.When described VELCRO being carried on carrier and using, described first binding agent can VELCRO and carrier described in good bond.
VELCRO described in the utility model embodiment can be realized by following method.
Accordingly, composition graphs 3, the utility model embodiment provides a kind of preparation method of VELCRO, comprises the following steps:
