Abstract
A high-strength polyvinyl alcohol adhesive and its preparation method, the main material of the adhesive is PVA, the coupling agent is borax or boric acid, its formulation is: PVA 12-14%, borax or boric acid 2-3% (5% water solution), water 84-85%. The preparation method of the adhesive comprises the steps of putting the main material, the coupling agent and the water into a reaction kettle according to the formula, uniformly stirring at the speed of 40-50 rpm at normal temperature, heating to 92-98 ℃, and stirring at the speed of 60-70 rpm for 2-2.5 hours. The adhesive has the characteristics of high bonding strength, good heat resistance, low cost and the like, can be widely applied to bonding of wood and paper, and is particularly suitable for producing cement composite packaging bags.
Description
The present invention relates to a kind of ethenyl adhesive, specifically a kind of high strong polyviny alcohol binder and preparation method thereof.
Abbreviation with the PVA(polyvinyl alcohol) being the tackiness agent of major ingredient preparation, is that PVA is directly soluble in water at first, uses after adding suitable softening agent.This tackiness agent bonding force is very strong, but poor heat resistance, special hot water resistance is poorer, and rubber moulding will decompose in 45 ° of-50 ℃ of hot water, not have promotional value.
After nineteen sixty-five, the manufacturer of China handles (generally being formal) with the PVA acetal and makes polyvinyl formal (PVFO).PVFO has overcome above-mentioned shortcoming, but acetal technology is comparatively complicated, and cost is higher.There are a large amount of formaldehyde to overflow during use, stimulate eyes, also cause pollution environment.
Chinese patent 86104811 discloses a kind of " soluble polyvinyl acetals adhesive ", is the product of polyvinyl alcohol and dialdehyde reaction.This caking agent has the temperature resistant range and the better waterproof of broad.Its not only part is that bonding force is lower, cost height, contaminate environment.
The object of the present invention is to provide low high strong polyviny alcohol binder of a kind of bonding strength height, good heat resistance, tackiness agent mould modulus of elasticity height and cost and preparation method thereof, the characteristics that this method has is easy and simple to handle, technical process is short.
High strong polyviny alcohol binder of the present invention, its major ingredient is a polyvinyl alcohol, select the compound (borax or boric acid) of the coupling agent-water-soluble boron that has multiple effects such as anticorrosion, impermeable, tackify concurrently for use, utilize PVA to have the chemical property of secondary alcohol, with PVA linked reaction taking place, makes the PVA sex change generate the modified polyvinyl alcohol tackiness agent under given conditions.The prescription of this tackiness agent is: PVA is 12%-14%, and the compound of water-soluble boron is the 2%-3%(5% aqueous solution), water is 84%-85%.
The preparation method of tackiness agent of the present invention: with PVA, borax and water, pack in the reactor by above-mentioned prescription, the speed with 40-50 rev/min under the normal temperature stirs, and is warming up to 92 ℃-98 ℃, stirs 2-2.5 hour discharging with 60-70 rev/min speed.
Tackiness agent of the present invention shows that through the on probation of certain factory its bonding strength and initial viscosity are significantly improved, and is fine to hydrophobic paper/woven dacron compound sticking effect.Recombination velocity can reach 15-20 rice/minute, can be adapted to the requirement of mechanize big area recombining process, with common PVA tackiness agent relatively, have the following advantages:
1. select single auxiliary agent (consumption is seldom) for use, easy and simple to handle, shortened process.
2. reduce the consumption (about 2%) of PVA, saved industrial chemicals such as hydrochloric acid, formaldehyde and caustic soda, reduce cost about 20%.
3. bonding strength improves, and initial viscosity good (4000-4500cp.d) also has good adhesive effect to the lower polyester of surface energy, polyester-cotton blend or artificial silk.Performances such as binder film modulus of elasticity, fatigue resistance, heat-resisting water also be significantly improved (seeing Table 1).
4. prescription is simple, and is easy to operate, Nonpoisonous, non-environmental-pollution.The workman who generally has high chinesization can independent operation through training in 2-3 days.Equipment used only needs a reactor and simple detecting instrument (small-sized reactor can be made by oneself).
Embodiment 1: be used for the bonding of paper/woven dacron matrix material, join the 100kg tackiness agent, each component consumption (Wt): PVA is 14Kg, and borax is a 2Kg(5% water liquid), water is 84Kg.
Embodiment 2: being glued material is WALL CLOTH.Join the 100Kg tackiness agent, each amounts of components (Wt): PVA is 12kg, and borax is a 3kg(5% water liquid), water is 85kg.Each component of above-mentioned consumption is packed in the reactor, and the speed with 40-50 rev/min under the normal temperature stirs, and is warming up to 94 ℃, with 60-70 rev/min speed stir about 2-2.5 hour, and discharging.
At present, China's packaging industry development is very fast, and each based packaging material consumption is very big.Only with regard to cement, need all kinds of packing bags (except in bulk) about 4,000,000,000 every year, the paper of succeeding in developing in recent years/glass fibre folder muscle laminated bag, paper/cloth laminated bag, development is rapidly.Produce above-mentioned combined package bag, tackiness agent of the present invention is an ideal comparatively, also is absolutely necessary.In addition, tackiness agent of the present invention also can be widely used in the bonding of timber, paper, also can be used for pasting bookbinding, wallpaper (cloth) bonding etc. of page or leaf, books.Cost is than the low 30%-40% of general tackiness agent.Raw material is based on domestic, therefore has market outlook and very high social benefit preferably.
