preparation example Construction

[0048] A preparation method for preparing a reflective material adhesive for clothing, comprising the following preparation steps:

[0049](1) Preparation of fluorescent components

[0050] Mix the silane coupling agent, graphene and organic fluorescent agent evenly to obtain the fluorescent component;

[0051] (2) Preparation of flexible acrylic polymer

[0052] Polyurethane acrylate, 2-ethylhexyl acrylate, epoxy acrylate, and hydroxyethyl acrylate are free radically polymerized to obtain flexible acrylic polymers;

[0053] (3) Preparation of adhesive

[0054] Mix the flexible acrylic polymer and fluorescent components evenly, add hexamethylene diisocyanate, and react under stirring conditions for more than 1 hour; then add antioxidant, tackifier, ketimine and fluorescent components and stir evenly.

[0055] The pre-mixing of the fluorescent components in step (1) is to enable the organic fluorescent agent to be more efficiently loaded on the surface of the graphene, and t...

preparation example 1

[0065] 35 parts by weight of polyurethane acrylate, 25 parts by weight of 2-ethylhexyl acrylate, 4 parts by weight of epoxy acrylate, and 6 parts by weight of hydroxyethyl acrylate are used to initiate free radical polymerization through an initiator to obtain a polymerization with a molecular weight of about 350,000. Object 1.

preparation example 2

[0067] 60 parts by weight of 2-ethylhexyl acrylate, 4 parts by weight of epoxy acrylate, and 6 parts by weight of hydroxyethyl acrylate were initiated by an initiator for radical polymerization to obtain polymer 2 with a molecular weight of about 350,000.

Abstract

The invention provides a reflecting material bonding agent for a garment. The bonding agent is prepared from 100 weight parts of flexible acrylic polymers, 5 to 12 weight parts of a composite curing agents, 3 to 15 weight parts of tackifiers, 0.5 to 2 weight parts of organic fluorescent agents, 0.1 to 1 weight part of graphene, 0.1 to 1 weight part of silane coupling agents and 1 to 3 weight partsof antioxidants, wherein the composite curing agent is a mixture of hexamethylene diisocyanate and ketimine according to the weight ratio of 3:(1 to 2); the bonding agent with high toughness, high initial sticking force, high final sticking force and active warning effects is finally obtained. The inventio also provides a preparation method, application and a use method of the reflecting materialbonding agent.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to the field of reflective material adhesives for clothing, and more specifically to the field of preparation methods, applications and usage methods of the adhesive. Background technique [0002] Adhesives belong to the polymer composition materials used in daily life, and their application fields are very wide, but there are huge differences according to different actual use requirements. Now the most commonly used in the market are acrylic system, epoxy system, silicone system, polyurethane system, rubber system or a mixture of the above systems, which can be selected according to the needs of the application field. [0003] The conventional definition of reflective material is a material with reflective properties and high visual reminder performance. It is widely used in various road traffic safety facilities such as traffic sign markings, raised road signs, outline signs, traffic cone...
