Abstract
The present invention uses polychloroprene emulsion as main raw material and compounding material, and in the presence of NaCl aqueous solution the technological processes of mixing, coagulating, extruding and dewatering, flushing, drying and cutting to obtain the invented chloroprene rubber adhesive base material whose Mooney viscosity Ml3+4 100℃30-38, stripping strength (cotton canvas-cotton canvas) 182-193N/2.5 cm, soft adhesive film prepared by the base material, high crystallization speed, good permeability, strong bonding force and good initial viscosity, is suitable for bonding similar materials such as rubber, leather, fabrics, wood, metal, cement products, ceramics and the like and different materials, is used for bonding adhesives for shoes, and has the advantage of no degumming.
Description
The present invention relates to adopt sovprene emulsion and other compounding ingredient in the presence of the Nacl aqueous solution, to be processed into a kind of neoprene adhesive base.
Neoprene adhesive is the rubber adhesive of a class large usage quantity, most of chloroprene rubber stick all is single-component and energy self-vulcanizing, easy to use, and the chloroprene rubber glued membrane has good anti-combustion, the characteristic of anti-ozone and atmospheric aging and good oil resistant, advantages such as anti-solvent and chemical reagent, therefore be widely used in national defence, industrial and agricultural production and light and textile industries, architectural decoration, electron trade etc.In recent years along with the raising of development and national economy and living standards of the people, more and more big to the neoprene adhesive demand, but the main raw material of preparation neoprene adhesive relies on the bonding tailored version chloroprene rubber LDJ-240 of domestic production, its output can not satisfy the requirement of current preparation neoprene adhesive far away, become one of industrial chemicals of domestic shortage, the major part of also having to relies on the adhesive purpose chloroprene rubber of external import, explore for this reason that a kind of new approach-trial-production can substitute or part substitutes the new variety of adhesive purpose chloroprene rubber, imperative as the base-material of producing neoprene adhesive.
The object of the invention provides a kind of be used to the prepare base-material of neoprene adhesive and easy production technique thereof, makes its basic mechanical design feature that had both had general adhesive purpose chloroprene rubber, also has good adhesive-preparing technology performance and cost and is lower than like product.
Neoprene adhesive base of the present invention is to be sovprene emulsion and the transparent white carbon black of 48-55% by solid content, antioxidant d and emulsifying agent are that the raw material and the Nacl aqueous solution that adds 15-30% make through certain technical process processing, and its proportion of raw materials is:
Weight part
Sovprene emulsion (solid content 48-55%) 900
Toughener (transparent white carbon black) 0.1-5
Emulsifying agent (op-10) 0.1-4.5
Antioxidant d 0.1-2
The Nacl aqueous solution (15-30%) 700-1000
Concrete production craft step is as follows:
(1) by said ratio weighing polychlorostyrene fourth vac emulsion, transparent white carbon black is respectively charged in the feeder standby.
(2) by proportioning weighing emulsifying agent op-10, antioxidant d is put into the mixing tank mixing for standby use,
(3) put into collection surface by the Nacl aqueous solution of proportioning weighing 15-30%, start agitator, open feeder and mixing tank then, flow into cohesion in the collection surface simultaneously.
(4) water flushing behind the blob of viscose extrusion dehydration after will condensing, put into automatic constant-temperature drying machine intensification (65 ℃-70 ℃) drying again, the time of keeping dry is to take out after 30-50 hour, be cut into small pieces behind the cool to room temperature, put into automatic constant-temperature drying machine intensification (55 ℃-65 ℃) drying again, took out in time 20-24 hour
(5) be placed on and be pressed into thin slice, stripping and slicing on the shaper.
Process flow diagram is seen accompanying drawing 1.
Neoprene adhesive base of the present invention is light brown and light grey chip solid, and initial bonding strength is strong, and tack is good, stripping strength height (cotton sail sheet-cotton duck) 182-193N/2.5cm mooney viscosity Ml
100 ℃ 3+430-38, good penetrability is convenient to preparation, and leading indicator is better than like product (seeing Table 1), is that a kind of neoprene adhesive of excellent property is joined gum.
Table 1: neoprene adhesive base and adhesive purpose chloroprene rubber LDJ-240 technical indicator contrast table
With the tackiness agent of this neoprene adhesive base preparation, glued membrane softness, bonding force is strong, crystallization velocity is fast, have the general character and the satisfactory stability of adhesive purpose chloroprene rubber, be applicable to rubber leather, fabric, timber, metal, cement products, pottery, the same type of material of spongy rubber etc. and differing materials bonding.Be particularly useful for the adhesive for shoes aspect, try out through relevant one factory, solving the problem of coming unglued has prominent special effect, because this base-material technology of production is simple, power consumption is few in addition, and cost is low,
Fig. 1 is for producing the neoprene adhesive base process flow diagram
Embodiment 1,2, and 3:
Press the base-material of the different ingredients production of aforementioned technical process and raw material:
The neoprene adhesive base that example 4 usefulness examples 2 prescriptions are produced is used for the prescription that shoe-making industry sticks with glue agent
Raw material ratio (weight part)
Homemade or import adhesive purpose chloroprene rubber 50
Base-material 50 with example 2 prescription productions
Light magnesium oxide 5
Light zinc oxide 4
Antioxidant d 1.5
Resol 35
White carbon black 14
Toluene 380-420
Stripping strength 〉=the 113N/2.5cm of the bonding leather-rubber of tackiness agent that is mixed with is used for shoe industry, does not find degumming phenomenon.
