Embodiment Construction

[0014] A wear-resistant, antistatic, water-based and anti-seepage container sealant is prepared from the following component raw materials in weight (kg):

[0015] Polyacrylate emulsion 40 with a solid content of 40%, neoprene latex 5 with a solid content of 40%, sodium petroleum sulfonate 0.5, rosin 3, liquid paraffin 2, titanate coupling agent 3, expanded graphite 10, lithium soap Stone 3, corundum powder 30, tributyl citrate 3, potassium sorbate 0.5, epoxy soybean oil 0.5, water 10.

[0016] A preparation method of wear-resistant antistatic water-based anti-seepage container sealant, comprising the following steps:

[0017] (1) Mix polyacrylate emulsion and neoprene latex evenly and stir at 1000 / min for 0.5h to obtain component A;

[0018] (2) First mix rosin, liquid paraffin, epoxidized soybean oil and tributyl citrate and stir at 80°C for 0.5-1h, then add titanate coupling agent and stir at 100°C for 10min, add petroleum sulfonic acid after cooling Stir sodium and water...

Abstract

The invention discloses a sealant used for a wear-resisting antistatic waterborne anti-seepage container and a preparation method of the sealant. The sealant is prepared from, by weight, 40-60 parts of polyacrylate emulsion with the solid content of 40-50%, 5-10 parts of neoprene latex with the solid content of 40-50%, 0.5-1 part of petroleum sodium sulfonate, 3-5 parts of rosin, 2-4 parts of liquid paraffin, 3-5 parts of titanate coupling agent, 10-15 parts of expanded graphite, 3-5 parts of hectorite, 30-40 parts of emery powder, 3-5 parts of tributyl citrate, 0.5-1 parts of potassium sorbate, 0.5-1 parts of epoxidized soybean oil and 10-15 parts of water. The sealant has the advantages of being high in elasticity, water resistance and seepage resistance, excellent in sealing performance, good in durability, high in safety coefficient, long in service life and environmentally friendly, and resisting abrasion and static electricity.

Description

technical field [0001] The invention relates to the technical field of sealants, in particular to a wear-resistant, antistatic, water-based, seepage-proof container sealant and a preparation method thereof. Background technique [0002] Sealant is a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of cohesion. It is an adhesive used to fill the gap in the configuration and play a sealing role. play an important role. In recent years, with the rapid development of the container transportation industry, sealant, as the main auxiliary material in the container manufacturing process, has received more attention on its performance. Traditionally, solvent-based butyl rubber or neoprene sealants are used for container sealing. This type of sealant has a strong odor and a large amount of VOC emissions, which may cause environmental pollution and even harm the human body, and cannot meet environmental protection requi...
