Abstract
The invention relates to the technical field of glue and particularly relates to a high-performance ultraviolet-curable modified adhesive and a preparation method thereof. The high-performance ultraviolet-curable modified adhesive is prepared from the following components in parts by weight: 50-60 parts of modified polyurethane acrylate, 1-2 parts of pigments, 2-5 parts of a photopolymerization initiator, 10-20 parts of an active diluent and 1-5 parts of a coupling agent. By adding the self-made modifier into polyurethane acrylate and by virtue of a combined effect with a silane coupling agent, many performances such as the bonding strength, toughness, water resistance, heat resistance, damp-heat aging resistance and durability of the adhesive are remarkably improved.
Description
Technical field
The present invention relates to glue technical field, particularly relate to a kind of high-performance ultraviolet cured modified adhesive and preparation method thereof.
Background technology
In recent years, along with people are to the raising day by day of environmental requirement, the development of solvent-free expediting setting type resin is progressively paid attention to.Ultraviolet photo-curing cementing agent significantly can reduce the volatilizable organism of VOC() content, and by solidifying immediately after ultraviolet light irradiation during room temperature.Therefore, compared with traditional tackiness agent, ultraviolet photo-curing cementing agent has the advantages such as pollution-free, quick solidifying, is a kind of environmentally friendly tackiness agent, and has been widely used in the fields such as optics, electronics, medical treatment, automobile and precision instruments.
As the major ingredient of ultraviolet photo-curing cementing agent, after UV-irradiation process, physicochemical change can be there is within a short period of time in urethane acrylate.Compared with or hot setting adhesive dry with traditional natural, ultraviolet photo-curing cementing agent except having that solidification rate is fast, energy-saving and cost-reducing, adhesiveproperties is excellent and to except the advantages such as base material is applied widely, also not containing materials such as VOC.But, many performances of ultraviolet photo-curing cementing agent prepared by urethane acrylate still advantage with improve further, along with the raising of people's standard of living, in the face of the new standard new demand of making rapid progress, urethane acrylate class ultraviolet photo-curing cementing agent obviously can not meet market completely on the market at present.
Summary of the invention
The present invention is directed to above-mentioned background technology, a kind of high-performance ultraviolet cured modified adhesive and preparation method thereof is provided.
For realizing the object of the invention, the technical solution used in the present invention is as follows:
A kind of high-performance ultraviolet cured modified adhesive, is characterized in that: count by weight, is prepared from: modified urethane acrylate by following raw material: 50 ~ 60 parts; Pigment: 1 ~ 2 part; Photoepolymerizationinitiater initiater: 2 ~ 5 parts; Reactive thinner: 10 ~ 20 parts; Coupling agent: 1 ~ 5 part;
Described modified urethane acrylate is prepared from by following steps: PTMG mixed with polypropylene glycol, is heated to 100 ~ 120 DEG C and continues 1 ~ 2 hour, adds dimethylolpropionic acid and stir continuation heating 10 ~ 20min; Be cooled to 70 ~ 80 DEG C subsequently, add isophorone diisocyanate mix and blend 2 ~ 4h; Be cooled to 50 ~ 60 DEG C, add acrylate and Resorcinol mix and blend 1 ~ 2h and get final product.
Further, the high-performance ultraviolet cured modified adhesive of described one is counted by weight, is prepared from: modified urethane acrylate by following raw material: 55 parts; Pigment: 1 part; Photoepolymerizationinitiater initiater: 5 parts; Reactive thinner: 15 parts; Coupling agent: 3 parts.
Further, described reactive thinner is 2-HPMA or diethylene glycol monoacrylate.
Further, described Photoepolymerizationinitiater initiater is phenyl benzophenone, dihydroxy benaophenonel or said mixture.
Further, described coupling agent is 3-propyl trimethoxy silicane.
Present invention also offers a kind of making method of above-mentioned a kind of high-performance ultraviolet cured modified adhesive, comprise the following steps: by modified urethane acrylate, pigment, reactive thinner, coupling agent, abundant mixing is also heated to 30 ~ 50 DEG C of stirring 10 ~ 30min, add Photoepolymerizationinitiater initiater again, stir, then leave standstill cooling and get final product.
The invention provides a kind of high-performance ultraviolet cured modified adhesive and preparation method thereof, beneficial effect is as follows:
A kind of high-performance ultraviolet cured modified adhesive of the present invention and preparation method thereof, because because electrostatic interaction makes ion chain generation close to each other " ion cluster " in modified urethane acrylate, and the bonding strength of the formation of ion cluster to tackiness agent has strengthening action, and with silane coupling agent acting in conjunction, significantly improve many performances such as the bonding strength of tackiness agent, toughness, water tolerance, thermotolerance, wet and heat ageing resistant and weather resistance.And the low murder by poisoning environmental protection of the present invention, can not impact the human or animal of contact product, meet the monitoring requirement of country to Product quality and safety.
