Abstract
The present invention relates to neoprene type flame-retardant spray adhesive and a preparation process thereof, and is characterized in that the chloroprene rubber type flame-retardant spray adhesive is composed of dichloromethane, a 6# oil solvent, toluene, rosin, terpene resin, triphenyl phosphate, chloroparaffin and neoprene. The flame-retardant spray adhesive of the present invention is prepared by that by a method of stirring, the rosin, the terpene resin and the triphenyl phosphate are completely dissolved in a mixed solvent composed of the dichloromethane, the 6# oil solvent and the toluene until a homogeneous transparent solution is formed; finally, the neoprene is added to the homogeneous transparent solution and is continuously stirred at normal temperature until completely dissolved. The flame-retardant spray adhesive of the present invention has the advantages of outstanding performance of fire retardance, favorable adhesiveness and high stability of products.
Description
Technical field
The present invention relates to a kind of tackiness agent, relate to a kind of chloroprene rubber type flame-retardant spray adhesive and preparation method thereof specifically.
Background technology
Spray glue is a kind of infant industry tackiness agent that development in recent years is come out.It has suitable viscosity, bonding force and suitable time of drying, can utilize spray gun to be sprayed on the adherend surface, forms uniform adhesive linkage.Spray glue through suitably dry, by sticking face pressing, has just been finished adhesion process after spraying.Compare with technique for sticking such as roll-in, brushings, consumption glue amount is little, and applying glue is even, uses more and more widely.
Spray glue is mainly used in the bonding of materials such as sponge, leather, leatheroid and timber.These materials are generally organism, easily burning.And their goods as furniture, case and bag, indoor decoration etc., often have harsh requirement to flame retardant properties.The flame retardant properties of spray glue has very big relation to the flame retardant resistance of goods.As raw materials for production, More and more factories, especially some export enterprises have proposed fire-retardant requirement to spray glue.
Spray glue product mainly contains two big classes at present.One class is a SBS type spray glue, is main raw material with the SBS Thermoplastic Elastomer, and cost is low, and tack is good.Another kind of is neoprene type spray glue, is main raw material with the chloroprene rubber, the bonding strength height, and temperature tolerance is good.Document [Chen Hui, the research of no triphen solvent-borne type neoprene spray glue, Fujian chemical industry, 2001,3:16-18] has been described the method for preparing neoprene spray glue.Yet because chloroprene rubber is easy to burning, oxygen index is lower, and after spray glue was applied to by bonding object, solvent evaporates finished, and the residual chloroprene rubber component that plays main adhesive effect can not suppress combustion processes, can't play fire retardation.
Summary of the invention
The object of the present invention is to provide a kind of chloroprene rubber type flame-retardant spray adhesive; Another purpose provides the preparation method of this spray glue.
We adopt nonflammable polymer as main raw material, and add fire retardant triphenylphosphate and clorafin, and the spray glue that obtains spraying back flame retardant properties is outstanding, can reduce disaster hidden-trouble, helps security against fire, thereby realizes purpose of the present invention.
Chloroprene rubber type flame-retardant spray adhesive provided by the invention, form by following compositions according to the mass fraction:
6～14 parts of methylene dichloride
26～46 parts of No. 6 solvent oils
8～18 parts of toluene
Rosin 10～18
1～10 part of terpine resin
1～10 part of triphenylphosphate
1～13 part of clorafin
5～19 parts of chloroprene rubbers
The preparation method of chloroprene rubber type flame-retardant spray adhesive provided by the invention may further comprise the steps:
(1) proportionally prepare methylene dichloride, No. 6 solvent oils and toluene stir under the normal temperature;
(2) in step (1) prepared solvent, proportionally add rosin, terpine resin, triphenylphosphate and clorafin stir up to dissolving fully, form the solution of transparent and homogeneous;
(3) add chloroprene rubber in the solution that step (2) obtains, normal temperature constantly stirs down, dissolves fully up to chloroprene rubber, promptly obtains flame-retardant spray adhesive.
The churning time of step (2) was generally 0.5～2 hour; The churning time of step (3) was generally 2～5 hours.
The major advantage of flame-retardant spray adhesive of the present invention comprises the following aspects:
(1) flame retardant properties is outstanding: since added can with the compatible fire retardant of spray peptizing agent-rubbery system, flame retardant effect is obvious, oxygen index can reach 23～24, can reduce disaster hidden-trouble, helps security against fire;
(2) cementability is good: have higher bonding strength, can satisfy the requirement of spraying operation commonly used;
(3) product stability is good: owing to consider the consistency of fire retardant and solvent-rubbery system especially in its preparation, so not stratified, shelf-stability is good.
