Abstract
The invention discloses a low-flammability aerosol adhesive. The low-flammability aerosol adhesive is characterized in that CO2 or mixed gas of CO2 and DME is adopted as a propellent, dichloromethane serves as a solvent, a small amount of SBS/SIS serves as an adhesive matrix, rosin serves as a thickening agent, liquid paraffin serves as a plasticizer and a wetting agent, and SiO2 micro powder serves as a dispersing agent and a reinforcing agent. CO2 or the mixed gas of CO2 and DME is adopted as the propellent, and thus flammability generated when DME and LPG are used is excluded; dichloromethane serves as the solvent, and thus the content of combustible matter of the whole adhesive system is further reduced; the proportion of CO2 and DME is regulated, it can be achieved that flames cannot be generated at the position of 15 cm at 20 DEG C in the testing method of the national standard of GBT21630-2008, and the ignition distance is smaller than 15 cm and meets the condition of class III aerosol.
Description
Technical field
The present invention relates to sizing agent field, particularly relate to a kind of use CO
2do the low combustible aerosol sizing agent of propellent.
Background technology
Aerial fog type sizing agent is glue spraying again, because of easy to use, is just subject to liking of numerous users to being born, aerial fog type sizing agent promoting every profession and trade Simplified flowsheet, save energy, reduce costs, to increase the benefit etc. in play more and more important effect.Domestic aerial fog type sizing agent development time is shorter, when 2002, Shenzhen Hui Erte researches and develops the aerial fog type sizing agent of successfully domestic first flower for computer embroidery, aerosol sizing agent industry domestic afterwards starts development rapidly, and the figure of aerosol sizing agent all appears in industry-by-industry so far.
Because environmental problem, the propellent of aerosol develops into dme (DME), petroleum gas (LPG) by fluorochlorohydrocarbon, although these propellents reduce the impact on environment, but bring a potential safety hazard to aerosol---incendivity.Seek unity of standard according to international aerosol, the incendivity of aerosol by combustible content, mean calorie, light distance, enclosed space incendivity determines.Because the incendivity of dme (DME) and petroleum gas (LPG) is very high, so use them to judge that all belonging to II " inflammable " or I " very easily fires " as the aerosol incendivity of propellent.For using fluorochlorohydrocarbon before, the combustible manufacturer of aerosol need not be considered, then the incendivity problem occurred after using dme (DME) and petroleum gas (LPG) makes aerosol be divided among " inflammable " article, this causes very large puzzlement to the producer of numerous production aerosol, what China's " hazardous chemical catalogue " was clear and definite is classified as I class aerosol as hazardous chemical thus carries out supervision, this working condition making aerosol producer must possess Class A just can produce this series products, concerning unusual trouble numerous aerosol producer, so for the producer not possessing Class A working condition, the incendivity reducing aerosol has become unique channel.
Summary of the invention
For solving the problem that existing aerosol sizing agent incendivity is easily caused danger by force, the invention provides a kind of low combustible aerosol sizing agent, this sizing agent not only can retain the performance of existing aerosol sizing agent, and incendivity is poor, improves security.
The technical scheme that the present invention solve the technical problem is, designs a kind of low combustible aerosol sizing agent, it is characterized in that, adopts CO
2or CO
2with the mixed gas of dme (DME) as propellent, take methylene dichloride as solvent, SBS/SIS is as sizing agent matrix, and rosin is tackifier, and whiteruss is softening agent and wetting Agent for Printing Inks, SiO
2micro mist is as dispersion agent, toughener.
Compared with prior art, its beneficial effect is in the present invention: use CO
2make propellent or use CO
2with dme (DME) mixture as propellent eliminate use dme (DME) and petroleum gas (LPG) time incendivity, as solvent, the combustible content of whole sizing agent system is reduced with methylene dichloride further, regulate CO
2with the ratio of dme (DME), with the testing method of national standard GB/T 21630-2008, can reach and can not produce flame at 15cm place 20 DEG C time, so light distance < 15cm, meet III class aerosol condition.Stripping strength and adhesiveproperties and existing aerosol sizing agent contrast similar.The present invention is with CO
2cook propellent, the incendivity of the aerosol sizing agent obtained obtains remarkable improvement.
Embodiment
Mainly in conjunction with specific embodiments a kind of low combustible aerosol sizing agent is described in further detail below.
A kind of low combustible aerosol sizing agent (abbreviation sizing agent) of the present invention, is characterized in that, adopt CO
2or CO
2with the mixed gas of dme (DME) as propellent, take methylene dichloride as solvent, a small amount of SBS/SIS is as sizing agent matrix, and rosin is tackifier, and whiteruss is softening agent and wetting Agent for Printing Inks, SiO
2micro mist is as dispersion agent, toughener.
Glue composition weight percent hundred ratio of described sizing agent is as follows:
(1) SBS/SIS of 0.5%-1%;
(2) rosin of 25%-35%;
(3) methylene dichloride of 44%-73%;
(4) SiO of 0.5%-10%
2;
(5) whiteruss of 1%-10%;
(6) the pure CO of (1) ~ (5) gross weight 10%-15%
2or 2%-10%CO
2with the mixture of the dme of 5%-35%.
Described SBS/SIS has two phase structure, obtained sizing agent excellent performance.SBS is a kind of thermoplastic elastomer, shows the elasticity of rubber at normal temperatures, again can plasticizing forming under high temperature, is with vinylbenzene and divinyl for raw material, by without the triblock copolymer stopping the polymerization of negatively charged ion method.SIS is the one of styrene analog thermoplastic elastomer, is the segmented copolymer of vinylbenzene and isoprene.
Described rosin adopts not easily oxidized staybelite.
Described methylene dichloride boiling point is low, and rate of drying is fast, and residence time short easy decomposition in atmosphere, has fewer environmental impacts.
Described SiO
2for one or several mixing in particle diameter 6.5 μm of-10nm, to the performance of sizing agent, there is obvious reinforced effects, and whiteruss successful in plasticising and moisturizing.
Add the pure CO of 10%-15%
2or 2%-10%CO
2sizing agent can be made with the mixture of dme (DME) (weight ratio) of 5%-35% to reach as propellent and make the identical atomizing effect of propellent with dme (DME) or petroleum gas (LPG).
Sizing agent of the present invention is can bear the pressure pan of 1.8MPa pressure as container, product pressure test result: 30 DEG C is 0.81MPa; 40 DEG C is 0.85MPa; 45 DEG C is 0.91MPa; 50 DEG C is 0.96MPa; 55 DEG C is 0.96MPa.Be heated to 60 DEG C of tank bodies undeformed, atomizing effect is good, can use safely.
