One-component polyurethane foam caulk with quick-drying glue gun

Abstract

The invention discloses an instant glue gun for a single-component polyurethane foam joint mixture. The instant glue gun comprises a gun body provided with a gun handle, wherein a glue injecting tube and a drying aid tube are parallelly arranged at the front end of the gun body; a mixer is assembled at the front ends of the glue injecting tube and the drying aid tube; a glue injecting mechanism connected with a polyurethane foam joint mixture tank body is arranged between the glue injecting tube and the gun body; a drying aid adding mechanism communicated with the drying aid tube and used for being connected with a drying aid tank body is arranged on the glue injecting tube; and a discharging control mechanism matched with the gun handle and used for controlling the discharging speeds of both the glue injecting mechanism and the drying aid adding mechanism is arranged on the gun body. The instant glue gun provided by the invention is cooperatively used with the single-component polyurethane foam joint mixture and a drying aid; before the instant glue gun sprays foam, the liquid drying aid and the single-component polyurethane foam joint mixture can be sufficiently mixed in the mixer; and therefore, not only can the instant drying effect be achieved, but also the glue waste can be avoided, and the construction cost can be reduced when the operation is facilitated.

Description

technical field [0001] The invention relates to a glue gun, in particular to a glue gun used for polyurethane foam caulking agents. Background technique [0002] At present, the domestic polyurethane foam sealants are mainly single-component. The one-component polyurethane foam sealant is a moisture-cured, multi-purpose polyurethane foam-filled elastic sealing material. The nozzle sprays the aerosol colloid to the site to be constructed, and completes the molding, foaming, bonding and sealing process in a short period of time. The cured foam elastomer has bonding, waterproof, thermal expansion and contraction resistance, heat insulation, sound insulation and even flame retardant And other excellent performance, so the application is more extensive. [0003] However, the surface-drying time of one-component polyurethane foam sealant is generally within 10 minutes (at a room temperature of 20°C), and the full-drying time varies with the ambient temperature and humidity. For e...

Problems solved by technology

However, most of the traditional glue guns are designed for one-component polyurethane foam caulking agent, with only one glue injection mechanism, which cannot meet the requirements of one-component polyurethane foam caulking agent combined with drying agent.
