Abstract
The invention provides an adhesive special for normal-temperature quickly-cured organic glass. The adhesive comprises an ingredient A and an ingredient B, wherein the ingredient A is a methyl methacrylate pre-polymer obtained by using methyl methacrylate and dibenzoyl peroxide as raw materials through free radical polymerization and having low polymerization degree. The ingredient B is a normal-temperature initiator system which consists of, by weight, the following ingredients: methyl methacrylate 30 parts, NN-dimethylaniline 1.5 parts and normal butanol 1 part. After the ingredient A and the ingredient B are mixed according to the 1:1 mass ratio, the adhesive can be used for bonding the organic glass. The adhesive has the advantages of being cured at normal temperature and quick to bond, a preparation and bonding process is simple, bonding strength is high, and the adhesive is special for the organic glass.
Description
Technical field
The invention belongs to caking agent field, relate to the agent of a kind of synthetic glass special bonding, particularly a kind of normal temperature expediting setting type synthetic glass special bonding agent.
Background technology
Synthetic glass (polymethylmethacrylate, be called for short PMMA) be a kind of special plastic, daily necessities, Industrial products have and applies more widely, general, synthetic glass initial feed mostly is tabular, need to give after its certain shape through post-production just can have use value, and in post-processed, the bonding of synthetic glass is a difficult problem.
At present, the caking agent of synthetic glass mainly contains two large classes: two component and single-component glue, and two component comprises multi-purpose adhesive, epoxy resin glue etc., and single-component glue is dissolved by synthetic glass bonding plane, then solvent is evaporated dry carry out bonding, conventional chloroform.Find that these two kinds of glue have shortcoming in actual use, the bonding overlong time of two component, speed is comparatively slow, can not produce in batches.And single-component glue is easily bubbled, turned white, and weathering resistance is poor, poisonous easily to environment.
Develop a kind of can the synthetic glass special adhesive of rapid link at normal temperatures, huge on the impact of synthetic glass secondary industry.
Summary of the invention
The object of the invention is to the defect overcoming prior art, the agent of a kind of normal temperature expediting setting type synthetic glass special bonding is provided, this caking agent has the advantage of ambient cure, rapid link, easy to use, preparation and technique for sticking simple, bonding strength is high, well solves the problem of existing synthetic glass caking agent.
The technical solution adopted for the present invention to solve the technical problems is:
The agent of a kind of normal temperature expediting setting type synthetic glass special bonding, comprise A, B two components, it is characterized in that: component A is the methyl methacrylate prepolymer with low polymerization degree obtained through radical polymerization for raw material with methyl methacrylate and dibenzoyl peroxide; B component is normal temperature initiator system, is made up of following components in mass portion: methyl methacrylate 30 parts, NN-xylidine 1.5 parts, and propyl carbinol is 1 part; After component A and B component mix according to mass ratio 1:1, can be used for the bonding of synthetic glass.
Present invention also offers the preparation method of the component A of a kind of normal temperature expediting setting type synthetic glass special bonding agent, step comprises: add in reactor by 30 mass parts methyl methacrylates, stir, add 0.5 mass parts dibenzoyl peroxide, at 80 DEG C of temperature, react 25min, obtain thick component A.
Synthetic glass special bonding of the present invention agent is two-pack, component A is the methyl methacrylate prepolymer with low polymerization degree obtained through radical polymerization for raw material with methyl methacrylate and dibenzoyl peroxide, methyl methacrylate pre-polymerization is Raolical polymerizable, C=C in methyl methacrylate disconnects, minimizing, and saturated hydrocarbyl can increase, accompanying drawing 1 is the infrared spectrogram of component A, compares, add 2950cm with methyl methacrylate infrared spectrogram
-1stable hydrocarbon base peak, 1640 cm
-1the C=C peak at place disappears.
The bonding mechanism of synthetic glass special bonding of the present invention agent is by two component Homogeneous phase mixing, carry out bonding to the bonding port of polylith synthetic glass, utilize synthetic glass and the good characteristic of methyl methacrylate consistency, caking agent is to synthetic glass dissolution of partial fiber surface, under the effect of B component normal temperature initiator, caking agent limit is dissolved organic glass edge and is carried out Raolical polymerizable, after solidification after a while, polymethyl methacrylate body well bonds together by caking agent, and bonding strength is high.This reaction is thermopositive reaction, and can generate bubble during reaction, adding of propyl carbinol can in order to eliminate bubble.
Beneficial effect of the present invention has:
Normal temperature expediting setting type synthetic glass special bonding of the present invention agent is a kind of Novel bonding agent being used as bonding organic glass specially of a two-pack, there is the advantage of ambient cure, rapid link, this caking agent can rapid link in-15 ~ 38 DEG C of temperature ranges, the bonding time, production efficiency was high within 15min.And caking agent solidified after-product good weatherability, non-whitening, non-foaming, add propyl carbinol in formula, reach the object of timely froth breaking, the caking agent after solidification does not have bubble, excellent optical performance.Caking agent main component is similar to synthetic glass, can combine closely with being reached by bonding organic glass, and adhesiveproperties is excellent, and its comprehensive mechanical property is better than by bonding poly (methyl methacrylate) plate.Caking agent manufacture craft of the present invention is simple, easily realizes suitability for industrialized production.
accompanying drawing illustrates:
Fig. 1 is the infrared spectrogram of synthetic glass special bonding agent component A of the present invention.
Embodiment
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with embodiment, the present invention is further illustrated.Should be appreciated that embodiment described herein only for explaining the present invention, being not intended to limit the present invention.
Embodiment
The agent of a kind of normal temperature expediting setting type synthetic glass special bonding, comprise A, B two components, component A is the methyl methacrylate performed polymer with low polymerization degree obtained through radical polymerization for raw material with methyl methacrylate and dibenzoyl peroxide; The preparation process of component A comprises: add in reactor by 30 Kg methyl methacrylates, stirs, adds 0.5Kg dibenzoyl peroxide, at 80 DEG C of temperature, react 25min, obtain thick component A.
B component is normal temperature initiator system, is made up of following components in mass portion: methyl methacrylate 30 Kg, NN-xylidine 1.5 Kg, and propyl carbinol is 1 Kg.
