Problems solved by technology

[0002] At present, the tapes used in ordinary computer embroidery include rubber type, hot melt adhesive type and acrylic polymer type. Due to the problem of poor aging resistance of rubber type and hot melt adhesive type, and the high cost of acrylic polymer, generally Tackifying resins are added to reduce costs, and the addition of tackifying resins will also reduce the weather resistance of the tape
In addition, the adhesive tape for computerized embroidery produced by the prior art still has the problem of few pasting times, which directly affects the operating cost of the customer.
The shortage of tapes for computer embroidery on the market is that when the tape is pasted on light-colored fabrics, if the pasting time is too long, for example, due to the operator, the pasted cloth is not embroidered in time and the tape is not torn off. If it exceeds 24 hours, the fabric will be polluted. The cause of it is that the additives of the tape or the small molecule substances are permeated to cause fabric pollution. To solve the above problems, it is necessary to go from the molecular weight design of the formula to all aspects of production. To be controlled, this is also several innovative technical backgrounds of the present invention

preparation example Construction

[0039] The preparation method of the double-sided pressure-sensitive adhesive tape for computerized embroidery of the present invention comprises the following steps:

[0040] (1), first add the main solvent, isooctyl acrylate, butyl acrylate, acrylic acid, vinyl acetate, hydroxyethyl acrylate taken by a certain weight ratio into a clean reactor, and then put it in another clean Add a certain weight ratio of auxiliary solvent and benzoyl dioxide in the high-level tank and stir to prepare an initiator titrant, then open the agitator of the reaction kettle, and heat up while stirring, and the temperature in the reaction kettle rises to 60- At 88°C, the initiator in the high-level tank was titrated dropwise into the reaction kettle, and the various components in the reaction kettle were polymerized under the action of the initiator to obtain a polyacrylate pressure with a certain molecular weight and a specific molecular weight distribution. Sensitive glue, spare;

[0041] (2), ...

Embodiment 1

[0047] Embodiment one: (1), add 95.0 kilograms of isooctyl acrylate, 13.0 kilograms of butyl acrylate, 4.0 kilograms of acrylic acid, 10.0 kilograms of vinyl acetate, 1.0 kilograms of hydroxy acrylate in the clean reactor equipped with stirring system and condensation system 170.0 kilograms of ethyl acetate and the solvent ethyl acetate of the main reaction, then add 0.60 kilograms of initiator benzoyl peroxide and 10 kilograms of solvent ethyl acetate for dissolving it in the overhead tank or the titration tank, and stir to prepare an initiator titrant , then open the stirrer of the reactor, and heat up while stirring, when the temperature in the reactor rises to the temperature range of 60-88 ℃, the initiator in the high-level tank is titrated dropwise into the reactor, the reactor Each component inside is initiated according to the theory of free radical initiation under the action of the initiator, and the polyacrylate pressure-sensitive adhesive is obtained by solution pol...

Embodiment 2

[0051] Embodiment two: (1), add 90.0 kilograms of isooctyl acrylate, 13.0 kilograms of butyl acrylate, 4.0 kilograms of acrylic acid, 9.0 kilograms of vinyl acetate, 1.0 kilograms of hydroxy acrylate in the clean reactor equipped with stirring system and condensation system 134.0 kilograms of ethyl acetate and the solvent ethyl acetate of the main reaction, then add 0.60 kilograms of initiator benzoyl peroxide and 10 kilograms of solvent ethyl acetate for dissolving it in the overhead tank or the titration tank, and stir to prepare an initiator titrant , then open the stirrer of the reactor, and heat up while stirring, when the temperature in the reactor rises to the temperature range of 60-88 ℃, the initiator in the high-level tank is titrated dropwise into the reactor, the reactor Each component inside is initiated according to the theory of free radical initiation under the action of the initiator, and the polyacrylate pressure-sensitive adhesive is obtained by solution poly...

Abstract

The invention relates a double sided pressure-sensitive adhesive tape for computer embroidery and a preparation method thereof. The double-sided pressure sensitive adhesive tape comprises base material, a pressure-sensitive adhesive layer coated on the two sides of the base material and a release paper layer; wherein, the pressure sensitive adhesive layer is prepared by being coated with pressure sensitive adhesive which is prepared by the following components according to the parts by weight: 80.0-100.0 parts of 2-ethylhexyl acrylate, 8.0-15.0 parts of butyl acrylate, 3.0-7.5 parts of acrylic acid, 8.0-15.0 parts of vinyl acetate, 1.0-7.5 parts of hydroxy-ethyl acrylate, 0.20-1.0 part of benzoyl peroxide, 120.0-200.0 parts of main solvent, 5.0-30.0 parts of auxiliary solvent and 2.0-6.0 parts of crosslinking and curing agent solution. In the formula design of the invention, the molecular weight design dispersion coefficient is designed to be a little smaller, the molecular weight is not too large and the soft monomer is increased so as to improve the peeling strength, thus reaching the aim that the adhesive tape has high peeling performance and can be pasted repeatedly.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a double-sided pressure-sensitive adhesive tape for computer embroidery that can be used repeatedly and a preparation method thereof. Background technique [0002] At present, the tapes used in ordinary computer embroidery include rubber type, hot melt adhesive type and acrylate polymer type. Due to the problem of poor aging resistance of rubber type and hot melt adhesive type, the cost of acrylate polymer is relatively high. Both are added with tackifying resin to reduce the cost, and the addition of tackifying resin will also reduce the weather resistance of the tape. In addition, the computerized embroidery tape produced by the existing technology still has the problem of less sticking times, which directly affects the customer's operating cost. The shortage of tapes for computerized embroidery on the market is that when the tapes are pasted on light-colored fabrics, if the pasting time is...
