Abstract
The invention discloses a sealant for a storage battery. The sealant is characterized by comprising a component A and a component B, wherein the raw materials of the component A and the component B comprise monomers, elastomers, initiators, stabilizers, antifoaming agents and accelerants; the component A and the component B are mixed based on the weight ratio of 1:1 to prepare the sealant; the component A comprises 60 to 75% of monomer, 16 to 25% of elastomer, 4 to 8% of an initiator, 4 to 8% of a stabilizer, 0 to 0.5% of an antifoaming agent, and 0 to 1.5% of an accelerant; the component B comprises 65 to 80% of monomer, 10 to 20% of elastomer, 4 to 8% of an initiator, 4 to 8% of a stabilizer, 0 to 0.5% of an antifoaming agent, and 0 to 1.5% of an accelerant. Compared with a general acrylate adhesive, the sealant has the advantages that the curing time is increased by modification, so that the heat release is reduced, and as a result, the quality of an adhering or pouring sealing product can be ensured, and the adhering or pouring sealing product is applicable to the pouring sealing of a pole rod of the storage battery and the sealing of a cell cover; when in manufacturing of the sealant, the mixing ratio cannot be strictly controlled, and heating and curing are avoided, so that the production process of the storage battery can be simplified, and the production cost of the storage battery can be reduced.
Description
Technical field
The present invention
Relate to Chemical Engineering Technology
Field, especially
Relate to a kind of accumulator sealant that accumulator is played sealing function.
Background technology
Along with developing rapidly of China's battery industry, performance as the accumulator sealant being directly connected to accumulator quality is increasingly paid close attention to by brainstrust in industry, both at home and abroad in industry-by-industry, the sealant being widely used in battery industry mainly comprises the epoxy systems or polyurethane system adhesive being to solidify by amine or modified amine, epoxy systems adhesive is longer at room temperature required hardening time, the most even need to be heating and curing, and there is bigger fragility, therefore this system is the most undesirable as the encapsulant of polar post of lead acid batteries and groove lid；Polyurethane adhesive can meet the requirement of lead-acid accumulator fluid sealant in terms of key property and processing performance, but the production cost of polyurethane adhesive is higher, and most of users are difficult to accept.Therefore, based on case above, response type acrylate adhesive has good mechanical performance and to the adhesion property of glued material, stronger heat resistance and acid resistance, and can be with room temperature fast-curing, and the superior function of esters of acrylic acid adhesive enters accumulator sealant field
