Abstract
The invention discloses a waterproof sealant and a preparation method and application thereof, wherein the sealant is prepared from the following raw materials: hydroxyl terminated polybutadiene, polystyrene-polyethylene/propylene-polystyrene copolymer, tackifier and anti-aging agent. The sealant has good sealing and pasting effects and good waterproof performance, the peeling force of a test steel plate is larger than 5N/25mm after being taken out after being soaked in water for 24 hours, and the pasting problem of the door and window sealing strips under humid climate is met. The sealant of the invention is particularly suitable for PE materials, EPDM materials, spray painting doors and plastic doors.
Description
Technical Field
The invention relates to the field of glue, in particular to a waterproof sealant and a preparation method and application thereof.
Background
The sealant is a sealing material which has a certain cohesiveness, is deformed due to the shape of a sealing surface and is not easy to flow. According to the difference of vulcanization methods, the sealant can be divided into a wet air vulcanization type sealant and a chemical vulcanization type sealant; according to different forms, the sealant can be divided into paste sealant, liquid elastomer sealant and hot melt sealant; the construction performance can be divided into a curing type sealant and a non-curing type sealant, the application range of the sealant is very wide, and the sealant can bond leather, glass, metal, doors and windows, plastics, textiles and the like.
Most of sealant products sold in the current market can not meet the waterproof performance requirement, and the problem of degumming easily occurs in a humid environment, so that the current sealant can not meet the market requirement, and therefore, the development of a waterproof sealant is urgently needed.
Disclosure of Invention
The invention aims to provide a waterproof sealant and a preparation method and application thereof.
The technical scheme adopted by the invention is as follows:
one of the purposes of the invention is to provide a waterproof sealant, which is prepared from the following raw materials in parts by weight:
preferably, the sealant consists of the following raw materials in parts by weight:
more preferably, the sealant consists of the following raw materials in parts by weight:
preferably, the hydroxyl-terminated polybutadiene has a number average molecular weight of 50000 to 80000 g/mol.
Preferably, the polystyrene-polyethylene/propylene-polystyrene copolymer has a number average molecular weight of 100000 to 150000 g/mol.
Preferably, the tackifier is at least one selected from terpene resins, rosin resins, coumarone resins, petroleum resins, oil-soluble phenol resins, rosin glycerol esters, hydrogenated rosin pentaerythritol esters, and hydrogenated carbon 5 petroleum resins.
More preferably, the tackifier is selected from hydrogenated carbon 5 petroleum resins.
Preferably, the anti-aging agent is at least one selected from the group consisting of 2, 2-methylene-bis (4-ethyl-6-tert-butylphenol), the antioxidant DLTP, and the antioxidant BHT.
More preferably, the above anti-aging agent is selected from 2, 2-methylene-bis (4-ethyl-6-tert-butylphenol).
The invention also aims to provide a preparation method of the sealant, which comprises the steps of weighing the raw materials according to the components, adding the raw materials into an extruder, blending and extruding to obtain the sealant.
The invention also provides application of the sealant in PE materials, EPDM materials, spray painting doors and plastic doors.
The invention has the beneficial effects that:
1. the sealant has good sealing and pasting effects and good waterproof performance, the peeling force of a test steel plate is larger than 5N/25mm after being taken out after being soaked in water for 24 hours, and the pasting problem of door and window sealing strips under humid climate is met.
2. The sealant of the invention is particularly suitable for PE materials, EPDM materials, spray painting doors and plastic doors.
