preparation example Construction

[0063] The second aspect of the present invention provides a method for preparing special glue for rapid positioning, the steps comprising:

[0064] (1) pump the white electric oil, halogenated alkanes, and ester solvents into the stirring kettle, then put petroleum resin into the kettle, and start stirring;

[0065] (2) After the petroleum resin is completely dissolved, put into SBS rubber and continue stirring;

[0066] (3) After the SBS rubber is completely dissolved, add silicon dioxide and stir evenly.

Abstract

Belonging to the technical field of adhesives, the invention in particular relates to an adhesive special for quick positioning and a preparation method thereof. The adhesive special for quick positioning comprises the following components by weight: 30-50 parts of petroleum resin, 15-25 parts of SBS rubber, 0.5-3 parts of silica, 15-25 parts of n-heptane and 8-12 parts of haloalkane. The adhesivespecial for quick positioning prepared according to the invention has superstrong binding force and viscosity of over 100000, is lasting and firm after curing, has quick positioning effect, can position the vast majority of base material within 10 seconds, can bear load, and also has no need for support and no need for fixation by adhesive tape. With excellent repeated cohesiveness, and for skewbonding, wrong bonding and other errors occurring in the construction process, the adhesive can be subjected to secondary repeated bonding with affecting the final adhesive force. With a long open time up to 40-60min, the adhesive can better solve the large-area construction problem and saves manpower.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and more specifically, the invention relates to a special adhesive for rapid positioning and a preparation method thereof. Background technique [0002] Positioning glue is widely used in daily life and has many advantages in use, such as changing parts from finishing to general processing, which reduces the difficulty of processing; increases the bonding area of ​​parts and improves assembly efficiency, etc. [0003] In daily life, for example, in supermarkets, we see a lot of cartoned breakfast milk, black tea drinks and other products with straws. A plastic film-encapsulated straw is attached to the square carton, and this acts as a bond. The colloid is a kind of positioning glue. [0004] However, although there are already many hot melt adhesives used for this purpose on the market, they all have many shortcomings. Some positioning adhesives have poor weather resistance, and the rapid pos...
