Abstract
The invention discloses a releasing agent for a cast-on strap (COS). The releasing agent consists of the following substances in weight ratio: deionized water, coarse cork powder, fine cork powder and an adhesive in a weight ratio of 100 to 2 to 2 to 1, wherein the moisture contents of the coarse cork powder and the fine cork powder are less than 1 percent; and all the coarse cork powder passes through a 150-mesh screen, and all the fine coarse cork powder passes through a 200-mesh screen. A method for producing the releasing agent comprises the following steps: boiling the deionized water; adding the adhesive to the boiled water, sufficiently stirring and boiling the additive for 3 minutes until the adhesive is dissolved in water or fine crystals uniformly suspend in water and stopping heating; firstly adding the coarse cork powder and sufficiently stirring the mixture until the mixture is uniform after the heating is stopped, and then adding the fine cork powder, and sufficiently stirring the mixture until the mixture is uniform; and sealing the uniformly stirred releasing agent and standing for 12 hours, and storing the releasing agent in a shade and dark place. When a battery is produced the releasing agent can be adopted to help release the busbar from a die smoothly to a great extent, avoid die sticking and uniformly jet the die and has good heat insulation performance.
Description
Technical field
The present invention relates to the welding fabrication technology of maintenance-free lead accumulator, particularly a kind of cast-on strap releasing agent.
Background technology
In the lead-acid accumulator bus-bar forming process, the releasing agent subsidiary products that is absolutely necessary along with the requirement of battery territory of use and environmental condition is more and more higher, requires also more and more higher to battery quality.Guarantee that battery quality just must have good power supply performance, and bus-bar is an important component part of battery, also is the only way which must be passed of battery inside and outside electric current, so the quality of bus-bar is one of key factor that influences battery performance.When present most of producer carries out the COS cast-on strap, use be traditional releasing agent, all contain silicate in traditional releasing agent, as sodium metasilicate, be commonly called as waterglass, when using the releasing agent cast welding that contains silicate following some problem is arranged: (1) stripping result is poor, easily sticking to mould; (2) the bus-bar quality is inconsistent, and for example: the surface is rough and uneven in surface, and one group of central bus-bar variable thickness causes; (3) big to the mould damage, be difficult to remove, reduce die life; (4) releasing agent is inhomogeneous, and heat-insulating property is poor; (4) composition and process for preparation complexity if any a step mistake, then can cause whole releasing agent not play a role; (5) consumption is big, the cost height.
Summary of the invention
The objective of the invention is to: a kind of cast-on strap releasing agent is provided, and the bus-bar that adopts this releasing agent to produce when producing battery can improve the smooth demoulding of bus-bar to a great extent, and jet mould is even, good heat insulating.
Technical solution of the present invention is: this releasing agent is made up of according to weight ratio following material: deionized water: thick cork powder: soft wood powder: adhesive=100:2:2:1.
Wherein, the moisture of thickness cork powder is less than 1%, and thick cork powder 100% is analysed by 150 mesh sieves, and soft wood powder 100% is analysed by 200 mesh sieves.
The production method of this releasing agent is as follows:
(1) deionized water is boiled;
(2) in above-mentioned boiling water, add adhesive and fully stir and boiled 3 minutes, in the water-soluble or even water in suspension of fine crystals, stop heating until adhesive;
(3) stop heating after, add earlier thick cork powder and also be stirred well to evenly, add soft wood powder again and stir;
(4) the releasing agent sealing and standing 12h that stirs, keep in Dark Place in shady and cool place.
The present invention has the following advantages: 1, releasing agent does not contain the silicate composition, has solved to contain silicate releasing agent sticking to mould problem, thereby has avoided bus-bar sticking to mould and damage mould; 2, releasing agent forms uniform releasing agent layer, guarantees the smooth demoulding of bus-bar, guarantees the bus-bar smooth surface, the thickness homogeneous; 3, adopt the thickness cork powder, can play good insulation effect; 4, releasing agent is even, and mould is not had damage, is easy to remove, and does not influence die life; 5, releasing agent composition and process for preparation are simple, and consumption is few, save cost.
The specific embodiment
Embodiment: produce releasing agent according to following concrete steps:
(1) deionized water is boiled;
(2) in above-mentioned boiling water, add adhesive and fully stir and boiled 3 minutes, in the water-soluble or even water in suspension of fine crystals, stop heating until adhesive; Wherein, the weight ratio of deionized water and adhesive is 100:1;
(3) stop heating after, add earlier thick cork powder and also be stirred well to evenly, add soft wood powder again and stir; Wherein, the weight ratio of deionized water and thickness cork powder is 100:2:2;
(4) the releasing agent sealing and standing 12h that stirs, keep in Dark Place in shady and cool place.
