In the future, it will be widely used in mobile communication tools and equipment, as well as electric vehicles and other fields, and its potential demand is huge.

[0003] At the same time, lithium battery tape is widely used in lithium-ion batteries to play the role of insulation and fixation. It is an indispensable and important material for lithium-ion batteries. In order to make lithium batteries have good stability under high temperature extreme conditions such as production and use, the use of tape needs to ensure that lithium batteries can maintain structural stability and unchanged chemical properties for a long time in high temperature environments, without short circuits, leakage, liquid leakage and other problems, and can adapt to various space bonding.

[0004] However, the existing tapes are all used for bonding two planes and belong to plane application tapes.

[0016] The steps of forming the base layer include:

[0017] Prefabrication step: dispersing acrylic staple fibers to obtain acrylic staple fiber pre-dispersed suspension;

[0018] The first mixing step is to mix the natural rubber, styrene-butadiene rubber, acrylic staple fiber pre-dispersed suspension and functional additives to obtain acrylic staple fiber masterbatch;

DETAILED DESCRIPTION

[0027] Below, in conjunction with specific implementation modes, the present invention is further described:

[0028] A special-shaped adhesive tape for an electrolyte-resistant lithium battery, comprising a base layer, an adhesive layer and a release layer; the release layer, the adhesive layer and the base layer are stacked in sequence from top to bottom; the base layer is a three-dimensional shape; the base layer comprises the following effective ingredients in parts by weight:

[0029] Among them, the fiber length of acrylic staple fiber is 1-6mm.

[0030] The micron filler includes mica powder, micron silicon dioxide and micron zinc borate, and the mass ratio thereof is 10:(6-7):(0.8-1).

[0031] After micron filler mica powder, micron silicon dioxide and micron zinc borate are mixed, they are ground through a 300 mesh sieve to obtain. The matrix layer with mica powder as the main micron filler has high insulation, but the density of mica powder is large, and it is easy to settle in the system. Although its anti-settling property can be improved by reducing the size of micron mica powder, the agglomeration phenomenon of micron particles is more serious as the particle diameter decreases, affecting its dispersion and performance. In addition, the above-mentioned micron filler is dispersed in the matrix layer structure, because the surface area is large and a network structure is formed in the system, so these micron fillers also further improve insulation and flame retardancy while balancing its cost.

[0032] The micron filler has high group activity and contains a large number of hydroxyl groups, which can form hydrogen bonds with the hydroxyl groups on the surface of TPI, so that the micron filler and TPI can be firmly combined to form a strong network structure in the matrix layer, improve the strength of the matrix layer, and enhance the adhesion performance of the three-dimensional matrix layer so that it can be permanently bonded to the adhesive layer.

[0033] Mica powder has good insulation properties and stable nature. Even if it is oxidized, its product, oxidized mica powder, still has good insulation properties.

[0034] The functional additives include 1-2 parts of activator, 30-40 parts of carbon black, 0.8-1 parts of coupling agent, 0.5-0.7 parts of antioxidant, 0.3-0.6 parts of vulcanizing agent, 0-0.6 parts of antioxidant and 0.5-1 parts of accelerator, based on the total weight of the base layer. The carbon black filler component has good fluidity and wettability, and can penetrate into cavities and cracks to make the inside of the rubber layer denser, thereby effectively inhibiting the volume shrinkage caused by colloid decomposition.

[0035] The activator is at least one of vanadium acetylacetonate, tetramethylthiourea, triphenylphosphine, acetylacetone and n-butyraldehyde-aniline condensate 808. The activator can promote the cross-linking of active groups in natural rubber and styrene-butadiene rubber and improve the cohesion of the base layer.

[0036] The antioxidant is at least one of antioxidant 1010, antioxidant MB and antioxidant 168, which can improve the anti-aging property of the base layer.

[0037] The vulcanizing agent is one of an amine-containing compound and a sulfur-containing resin compound.

[0038] The effective ingredients of the adhesive layer include 80-100 parts by weight of styrene-butadiene latex, 15-25 parts by weight of polyisobutylene latex, 20-30 parts by weight of chloroprene latex, 5-10 parts by weight of zinc oxide and 10-30 parts by weight of terpene resin.

[0039] Among them, the release layer is a double-sided release material with a release force of 30g / in, which can protect the viscosity of the adhesive layer and facilitate unwinding.

[0040] The preparation method of the electrolyte-resistant lithium battery special-shaped tape comprises the steps of forming a base layer, forming an adhesive layer on the base layer, and forming a release layer on the adhesive layer.

[0041] The steps of forming the base layer include:

[0042] Prefabrication step: placing the acrylic staple fibers and the operating oil in a stirring kettle and stirring them evenly to disperse them, thereby obtaining a pre-dispersed suspension of the acrylic staple fibers;

[0043] The first mixing step is to add natural rubber, styrene-butadiene rubber, acrylic staple fiber pre-dispersed suspension, activator and vulcanizer into an internal mixer for mixing to obtain acrylic staple fiber masterbatch;

[0044] Secondary mixing step: mixing acrylic staple fiber masterbatch, TPI, carbon black, antioxidant and micron filler to obtain a masterbatch;

[0045] Three mixing steps: the masterbatch is cooled to room temperature, and then a coupling agent, a accelerator and an antioxidant are added to mix, discharge the glue, and shape it into a three-dimensional shape to obtain a base layer.

[0046] The process oil is an alkyl softener.

[0047] The step of forming the adhesive layer comprises: adjusting the pH value of styrene-butadiene latex emulsion to 9-10 with ammonia water and adjusting the pH value of chloroprene latex emulsion to 9-10 with a 5wt% dilute boric acid solution; stirring for 100-110 minutes at 300-320r / min, adding zinc oxide and terpene resin, kneading under the conditions of time 90-100min, speed 30-50r / min, and temperature 110-120°C, adding polyisobutylene latex and stirring for 16-20min, filtering with a 150-mesh filter cloth, and forming on a substrate layer to obtain an adhesive layer.

[0048] Styrene butadiene latex contains carboxylic acid, which increases the polarity of the molecular chain and thus improves its adhesion. Styrene butadiene latex is low in cost and environmentally friendly and safe, but it still has problems such as slow drying speed, poor initial adhesion, poor insulation performance, and stability that needs to be further improved.

[0049] The three-dimensional base layer uses a blended modified emulsion of styrene-butadiene rubber and natural rubber as the main body of the base elastomer. It does not need to add a curing agent. Through the activator in the component, it can be quickly self-cured at low temperature. Assisted by carbon black filler, micron filler and TPI, the prepared three-dimensional base layer has resilience, good tensile properties, and high adhesion performance. It can adhere to the adhesive layer well and soak in the electrolyte for a long time without damage. By cooperating with the adhesive layer, the electrolyte resistance of the special-shaped tape in the lithium battery can be further improved, and the safe use factor of the lithium battery can be improved; at the same time, through the trace addition of antioxidants and vulcanizers, the three-dimensional base layer is given good corrosion resistance and aging resistance; the preparation method of acrylic staple fibers, coupling agents, and micron fillers can ensure that the micron fillers in the three-dimensional base layer are well and evenly dispersed without sedimentation, which is beneficial to the performance of insulation performance; the filling of micron fillers and mica powder particles with good flame retardant properties also improves the flame retardancy of the special-shaped tape. Electrolyte-resistant lithium battery special-shaped tape has good electrolyte corrosion resistance and bonding performance. It can maintain a high peeling force without debonding in long-term immersion in electrolyte, thus ensuring the safety performance of lithium batteries. Example
