Description
Technical field
The invention belongs to encapsulant technical field, and in particular to a kind of high viscosity polyurethane fluid sealant.
Background technology
Encapsulant just refers to that can bear seam displacement is embedded in the material in building joint to reach airtight, watertight purpose
Referred to as encapsulant.Sealing member material has metal material (aluminium, lead, indium, stainless steel etc.), also there is nonmetallic materials (rubber, modeling
Material, ceramics, graphite etc.), composite (such as rubber-asbestos board, aerogel blanket-polyurethane), but most commonly used is rubber-like
Elastomeric material.Polyurethane resin is widely used as a kind of main encapsulant raw material, but due to poly- ammonia
Ester is processed more difficult in itself so that product quality is relatively general, and adhesive strength can not meet use demand instantly so that
Adhesive effect when in use is poor.And polyurethane inoxidizability itself is general, easy aging after long-time use, color occurs
Become so that using effect is deteriorated.
The content of the invention
The present invention proposes a kind of high viscosity polyurethane fluid sealant, and the sealing adhesivity is strong, quality is good, easy to process, anti-zoned
Trace is good, ageing-resistant.
The technical proposal of the invention is realized in this way：
A kind of high viscosity polyurethane fluid sealant, according to the number of parts by weight, including following raw material：
70~90 parts of polyurethane resin, 10~20 parts of SBS, silane coupler
0.5~1 part, 3~6 parts of tackifier, 2~4 parts of crosslinking agent, 2~4 parts of propylene carbonate acid esters, 1~2 part of thixotropic agent, ultraviolet radiation absorption
10~20 parts of 1~3 part of agent and diatomite, the tackifier are the mixing of liquid-state epoxy resin, polyvinyl acetate and flyash
Thing.
Preferably, the silane coupler is selected from γ-(2,3- the third oxygen of epoxy) propyl trimethoxy silicane, γ-aminopropyl
Triethoxysilane, γ-aminopropyltrimethoxysilane, N- β (aminoethyl)-gamma-aminopropyl-triethoxy-silane, N- β (ammonia second
Base)-γ-aminopropyltrimethoxysilane, N- β (aminoethyl)-γ-aminopropyltriethoxy dimethoxysilane, N- β (aminoethyl)-
γ-aminopropyltriethoxy diethoxy silane or phenylaminomethyl triethoxysilane.
Preferably, the crosslinking agent is hydroxypropyl acrylate.
Preferably, the thixotropic agent is aerosil.
Preferably, the ultraviolet absorber is single benzoic acid resorcinol.
The preparation method of high viscosity polyurethane fluid sealant of the present invention：
By polyurethane resin, SBS, crosslinking agent, silane coupler and diatom
Soil stirring heating, temperature control open vacuum pumping negative pressure, Stress control is below -0.08MPa at 100 DEG C~120 DEG C；So
After cool to less than 70 DEG C, be passed through drying nitrogen and release vacuum, temperature control adds the propylene carbonate of formula ratio at 60~70 DEG C
Acid esters and tackifier stirring reaction, reaction adds thixotropic agent after terminating and ultra-violet absorber is well mixed, you can.
Beneficial effects of the present invention：
The present invention is using polyurethane as primary raw material, using SBS, silane coupled
Agent and diatomite coordinate the viscosity for enhancing fluid sealant, and final obtained product viscosity is strong, quality is good, easy to process, anti-scratch
Good, the ageing-resistant, Anti- tarnishing of property, using effect are good.Tensile strength has reached more than 5.2MPa, shear strength reached 4.5MPa with
On.According to GB/T13477《Test method for building sealants》, fluid sealant of the invention stretches caking property 900,000 times without destruction surely.
