Abstract
The invention provides a method for producing an organic silicon defoaming agent for papermaking. The produced product is a high-grade defoaming agent applied in the papermaking industry. The defoaming agent has excellent defoaming property, can be applied in each procedure in the papermaking industry for the purpose of defoaming and is convenient to use. The organic silicon defoaming agent has a defoaming effect superior to the defoaming effects of a fatty acid amide defoaming agent and a polyether defoaming agent but has a higher price, so the organic silicon defoaming agent is mostly used for producing high-grade paper. The following raw materials are used for producing the defoaming agent: dimethyl silicon oil, silica, alkylphenol polyoxyethylene ether, fatty acid polyglycol ester and sodium carbonate.
Description
Affiliated technical field:
Product of the present invention belongs to the chemical industry field of papermaking.
Background technology:
In pulp and paper industry, the foam processing is the thorny problem in producing.Slurrying unit operations after the rotary spherical digester discharging all has foam in various degree to exist up to painting process, and foam seriously affects ordinary production and paper quality.Therefore, people take many methods to eliminate the foam of paper pulp system, and coming froth breaking with chemical method is most widely used method in paper industry at present.Silicone defoaming agent be a kind of defoaming effect of using of paper industry preferably but the most expensive defoamer of price, be mainly used in the production of high-grade paper.Silicone defoaming agent generally includes silicone oil (or silicon cream) and two components of emulsifying agent, and both are indispensable.Used silicone oil generally is dimethicone, and silicon cream is then by dimethicone and improved silica preparation; Emulsifying agent uses non-ionic surface active agent, (oleophylic of surfactant or hydrophilicrty can be differentiated with the size of HLB value in 8～12 scopes to require its HLB value, the big more representative hydrophily of HLB value is strong more, the more little representative lipophile of HLB value is strong more, lipophilic surfactant HLB is lower, and hydrophilic surfactant active HLB is higher.Hydrophilic and oleophilic turning point HLB is 10.HLB is a lipophile less than 10, is hydrophily greater than 10), self non-foaming or low bubble, consumption generally is 5%～50% of a silicone oil (or silicon cream).The composition of silicone defoaming agent has determined it to have following feature: 1. on chemical constitution with other organic defoamer difference, active group is approximate nonpolar, with water, the material that contains alkyl or polar group association does not take place all.2. the froth breaking ability than other organic defoamer is strong.3. on chemical property, be inertia for general material, can be with foamer generation chemical reaction.4. organosilicon heat resistance, high and low temperature resistance are good.Silicon oil viscosity is just rising more than 200 ℃ gradually, and its silicon oxygen bond does not decompose.5. the flexibility of silicone oil, lubricity are good, so silicone defoaming agent helps improving the quality of coated paper.6. organosilicon is nontoxic, pollution-free.7. organosilicon weatherability, durability, ageing-resistant performance are given prominence to, and all can bring into play its usefulness under any environmental condition.8. organosilicon material intensity is low, and this point does not have adverse effect to the defoamer product.9. organosilicon product costs an arm and a leg.In sum, silicone defoaming agent has excellent comprehensive performances, and it can be applied to each operation of paper industry, and defoaming effect is better than fatty acid amide defoamer and polyether antifoam agent, but cost is higher, therefore is used for the production of high-grade paper more.
Summary of the invention:
In order to overcome the fatty acid amide defoamer and the polyether antifoam agent applicable surface is narrow, compare the defective that still has gap though result of use is good with silicone defoaming agent, the invention provides a kind of paper grade (stock) silicone defoaming agent: the froth breaking of this defoamer suppresses good, the wide accommodation of effect.Producing the raw material that this defoamer uses has: 1. 65 parts of dimethicones (major ingredient); 2. 5 parts of silica (modifier); 3. 25 parts of alkylphenol polyoxyethylene (emulsifying agent); 4. 4 parts of fatty acid polyethylene glycol esters (dispersant); 5. 1 part in sodium carbonate (being used to adjust the pH value of silicone defoaming agent).
The invention has the beneficial effects as follows: a kind of silicone defoaming agent of paper grade (stock) have nontoxic, good fluidity, easy to use, defoaming effect is good, is applicable to all process steps of paper industry slurrying, is mainly used in the production of high-grade paper.
The specific embodiment:
Embodiment:
The first step: in 65 parts of adding reaction vessels of dimethicone, temperature is brought up to 65 ℃, start agitator and stir, add 5 parts of silica slowly, stirred insulation reaction 1 hour with 30 rev/mins rotating speed.
Second step: temperature is adjusted to 55 ℃, add 25 parts of alkylphenol polyoxyethylene, stirring reaction 1 hour.Add 5 parts of fatty acid polyethylene glycol esters, continue to stir insulation reaction 0.5 hour.
The 3rd step: be cooled to normal temperature, continue stir, add an amount of sodium carbonate, obtain finished product after about adjust pH to 8.5.(because of the silicon product stability fairly good, so do not need to use stabilizing agent)
