Problems solved by technology

[0003] However, most of the nail-free glues on the market currently use SBS rubber and styrene rubber as the main material. Due to the poor aging resistance of SBS rubber and styrene rubber, this also leads to the aging resistance of the nail-free glue produced. Poor, unable to achieve normal use outdoors

Abstract

The invention discloses weather-proof nail-free glue capable of being used outdoors and a preparation method of the weather-proof nail-free glue. The weather-proof nail-free glue is mainly prepared from chloroprene rubber, weather-proof rubber, an environment-friendly solvent, filler, metal powder, active magnesium oxide, p-tert-butylphenol formaldehyde resin, tackifying resin, a coupling agent and an antioxidant. The invention has the advantages that: 1, the adhesive has high bonding strength and high curing speed; 2, the metal powder is added to reduce light and heat radiation, change the colloid expansion coefficient and prolong the service life; 3, after the glue is cured, the hardness is moderate; 4, the solvent system is environment-friendly and high in solid content; and 5, chloroprene rubber is matched with weather-proof rubber to serve as a main body, high temperature resistance and aging resistance are excellent, and the requirement for outdoor use can be met.

Description

technical field [0001] The invention relates to a weather-resistant nail-free glue for outdoor use and a preparation method thereof. Background technique [0002] Nail-free glue, also known as liquid nails, is a multifunctional decorative adhesive, mainly used for bonding and fixing various wood lines, door casing lines, plaster lines, floor tiles, various decorative pendants and various wallboard projects. In recent years, nail-free glue has gradually replaced nailing, drilling and other fixing methods, effectively avoiding noise and dust pollution, and also reducing damage to the house structure, and has been more and more widely used. [0003] However, most of the nail-free glues on the market currently use SBS rubber and styrene rubber as the main material. Due to the poor aging resistance of SBS rubber and styrene rubber, this also leads to the aging resistance of the nail-free glue produced. Poor, unable to achieve normal use outdoors. [0004] It can be seen from th...
