Embodiment 1

[0028] Take 40 kg of phenol, 15 kg of tert-butylphenol, 10 kg of resorcinol, 15 kg of formaldehyde, and 3 kg of glyoxal, put them in a 0.5-ton stainless steel reaction kettle, and react at 75-90°C for 3 hours to prepare Synthetic resin; then the above synthetic resin is placed in the VSH-0.5 cantilever double-helix mixer, 3 kg of monoethanolamine is added, 14 kg of polyester non-woven fabric is introduced, and the base material is stirred and mixed; then the base material is placed in CRM- 3 kiln-type drying tunnel, heated to 60-80 ° C for 50 seconds to pre-cure; then the pre-cured base material is rolled into a thin plate with a ZS type three-roll calender; then the obtained sheet is placed in a CRM-3 kiln-type drying tunnel , at 230-270°C, heat for 20 minutes to solidify and shape; take it out and cool it, and use a 20-ton cardboard roller cutter to cut it into colloidal lead-acid battery separators according to specifications.

Embodiment 2

[0030] Take 30 kg of phenol, 18 kg of tert-butylphenol, 15 kg of resorcinol, 20 kg of formaldehyde, and 1 kg of glyoxal, put them in a 0.5-ton stainless steel reaction kettle, and react for 2 hours at 75-90°C to prepare Synthetic resin; then the above synthetic resin is placed in a VSH-0.5 cantilever double-helix mixer, 2 kg of diethanolamine is added, 18 kg of polypropylene non-woven fabric is introduced, stirred and mixed into a base material; then the base material is placed in CRM- 3 kiln-type drying tunnel, heated to 60-80 ° C for 30 seconds for pre-curing; then the pre-cured base material is rolled into a thin plate with a ZS type three-roll calender; then the obtained thin plate is placed in a CRM-3 kiln-type drying tunnel , at 230-270°C, heat for 15 minutes to solidify and shape; take it out and cool it, and use a 20-ton cardboard roller cutter to cut it into colloidal lead-acid battery separators according to specifications.

Embodiment 3

[0032] Take 50 kg of phenol, 11 kg of tert-butylphenol, 5 kg of resorcinol, 12 kg of formaldehyde, and 5 kg of glyoxal, put them in a 0.5-ton stainless steel reaction kettle, and react at 75-90°C for 4 hours to prepare Synthetic resin; then above-mentioned synthetic resin is placed in VSH-0.5 cantilever twin-helix mixer, adds 5 kilograms of triethanolamines, introduces 12 kilograms of cotton fiber non-woven fabrics, stirs and mixes base material; Then base material is placed in CRM- 3 kiln-type drying tunnel, heated to 60-80°C for pre-curing for 15 seconds; then the pre-cured base material is rolled into a thin plate with a ZS type three-roll calender; then the obtained sheet is placed in a CRM-3 kiln-type drying tunnel , at 230-270°C, heat for 10 minutes to solidify and shape; take it out and cool it, and use a 20-ton cardboard roller cutter to cut it into colloidal lead-acid battery separators according to specifications.

Abstract

The invention provides a partition plate of a colloid lead-acid storage battery and a preparation method of the partition plate. The partition plate is prepared from the following substances used as raw materials based on percent by weight: 30-50% of phenol, 10-20% of tert phenol, 5-20% of resorcinol, 10-25% of formaldehyde, 1-5% of glyoxal, 1-10% of amine catalyst and 10-20% of non-woven fabric,wherein micropores are uniformly formed in the partition plate. According to the preparation method, the partition plate is formed by resin synthesis, substrate preparation, pre-curing, calendaring, curing and cutting according to the formula. The partition plate of the colloid lead-acid storage battery is made of thermosetting resin extremely resistant to oxidization, and the product is extremelyresistant to oxidization and has reliable mechanical strength and stability; and the non-woven fabric is used as a filler, water is used as a hole formation agent, hole formation is achieved by an extrusion method, the micropores are uniformly distributed, the pore diameter is small, and high porosity is achieved.

Description

technical field [0001] The invention relates to a battery component and a preparation method thereof, in particular to a colloidal lead-acid battery separator and a preparation method thereof. Background technique [0002] The AGM valve-regulated sealed lead-acid battery, which has been used for nearly two decades, is being replaced by colloidal lead-acid batteries that can overcome these shortcomings because of its short life, large self-discharge, and serious thermal runaway. In recent years, my country's colloidal lead-acid batteries have developed rapidly, and the separators used in colloidal lead-acid batteries are required to be extremely resistant to oxidation, minimal acid discharge, high porosity, and reliable mechanical strength and stability. It has become an important factor restricting the development of colloidal lead-acid batteries, and the separators of colloidal lead-acid batteries in the prior art are often difficult to meet the above requirements at the sam...
