Abstract
The utility model relates to a single-component polyurethane foam joint mixture tank, which comprises a tank body (1). The single-component polyurethane foam joint mixture tank is characterized in that a nozzle (2) is arranged at an opening at the upper end of the tank body (1), a sealing ring sleeve (3) is sleeved on the periphery of the nozzle (2), the sealing ring sleeve (3) is fixedly connected with a sealing ring (4) on the top portion of the tank body (1), the lower end of the nozzle (1) is provided with a sealing gasket (5), and a communicating hole is arranged on a lateral wall of the nozzle (2) located above the sealing gasket (5). The single-component polyurethane foam joint mixture tank is simple in structure, convenient in use and fine in sealing property, can be solidified and formed at one step after polyurethane foam in the tank is sprayed out, resolves technical difficulty that the existing polyurethane foam joint mixture is low in extension adhesive strength, low in flame-retardant level and the like during production and application, improves added value of products, strengthens marketing competence of enterprises, and is particularly suitable for being applied to seal of buildings.
Description
Technical field
The utility model relates to a kind of gap filler pot.
Background technology
To be the aerosol technology intersect the product that combines with the polyurethane foam technology to one-component polyurethane foam, and it is a kind of components such as polyurethane prepolymer, blowing agent, catalyst to be filled in special polyurethane products in the withstand voltage gas thing jar.When material sprays from the aerosol jar, the polyurethane material of foam shape can expand rapidly and with air or the matrix that touches in moisture generation curing reaction form foam.It is a kind of environmental protection and energy saving, construction material easy to use that OCF after the curing has multiple effects such as joint filling, bonding, sealing, heat insulation, sound-absorbing, is particularly useful for sealing and plugging and waterproof between plastic-steel or aluminum alloy doors and windows and body of wall.
But present one-component polyurethane foam jar all is a polymerization in adopting jar when using, thereby causes when using through twice foaming, promptly at first blows out foam shape body by the propellant polyurethane prepolymer, and foam shape body continues to generate CO with airborne reaction of moisture then
2, further making the volume expansion of foam shape, is the therefore last density that forms lower and have a cured foam (18 of certain rate of closed hole? OKG/M
3), along with the effusion slowly of the gas in the foams, low-density polyurethane foam like this has very large contraction tendency.And the size of shrinkage factor has bigger influence to its filling sealing effectiveness.When for example OCF being used for the sealing between plastic-steel door and window and the cement wall, shrinkage factor is excessive, will cause between foam and the body of wall to break away from, and forms the slit, causes body of wall cold bridge or drainage.
Summary of the invention
The purpose of this utility model then is at present the deficiencies in the prior art, a kind of good seal performance is provided, can makes the sealing agent of single component polyurethane foam jar of polyurethane foam one step foaming moulding.
The technical solution adopted in the utility model is as follows:
A kind of sealing agent of single component polyurethane foam jar, comprise tank body, the upper end open place that it is characterized in that tank body is provided with nozzle, the periphery of nozzle is with the sealing ring cover, the sealing snare is fixedlyed connected with the sealing ring at tank body top, the lower end of nozzle is provided with gasket seal, and the nozzle wall that is positioned at the gasket seal top is provided with intercommunicating pore.
The filler of loading in the described tank body is divided into two-layer up and down, and bottom is the base polyurethane prepolymer for use as packing layer, and the upper strata is the third butane dimethyl ether packing layer.
The beneficial effects of the utility model have:
Simple in structure, easy to use, good seal performance, can spray the back one-step solidification moulding by a jar interior polyurethane foam, solved low, the high inadequately technical barrier of flame retardant rating of tensile bond strength in the current cranny filler of polyurethane foam production practicality, promote added value of product, strengthen the market competitiveness of enterprise, be particularly suitable for being applied to the sealing of building.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with drawings and Examples:
As shown in Figure 1, the upper end open place of tank body 1 of the present utility model is provided with nozzle 2, and the periphery of nozzle 2 is with sealing ring cover 3, and sealing snare 3 is fixedlyed connected with the sealing ring 4 at tank body 1 top, the lower end of nozzle 1 is provided with gasket seal 5, and nozzle 2 sidewalls that are positioned at gasket seal 5 tops are provided with intercommunicating pore.The filler of loading in the tank body 1 is divided into two-layer up and down, and bottom is the base polyurethane prepolymer for use as packing layer, and the upper strata is the third butane dimethyl ether packing layer 7.The utility model is multi-sealed, has strengthened the sealing of tank body 1, by the unique design of layering filling filler and nozzle in the tank body 1,1 interior first premix a period of time of tank body is sprayed again, reaches one-step solidification moulding.
Other undeclared part that the utility model relates to is same as the prior art.
Claims (2)
