Abstract
The invention relates to a technological process for recycling a resin product from oil-containing calcium powder produced during a resin granulation process. Specifically, the technological process comprises the following steps of (1) adding the oil-containing calcium powder produced during a petroleum resin production process in a solvent oil produced during the resin granulation process under stirring, wherein the adding amount of the oil-containing calcium powder is 10-50% by weight of the solvent oil, a stirring speed is 150 rotations/minute, a stirring time is 10-60 min, stirring paddles used for stirring are in upper, middle and lower three layers, and a stirring direction is upward during the stirring process; (2) carrying out filter pressing on a turbid liquid stirred by the step (1) by using a plate and frame type filter press under a pressure of 0.4 MPa; and (3) drying the oil-containing calcium powder after the step (2) for 1-4 hours at a pressure of -0.1 MPa and under a temperature of 180 DEG C-240 DEG C. The technology provided by the invention is simple; a resin liquid carried in the treated oil-containing calcium powder is obviously reduced; a recovery rate of the resin product is high; and volatile organic materials in the calcium powder is few, thereby realizing utilization of wastes and being environment-friendly and economical.
Description
Technical field
The present invention relates to chemical field, particularly in a kind of oil-containing calcium powder produced from resin granulation process, reclaim the technical process of rosin products.
Background technology
Petroleum resin are fractions of petroleum cracking institute by-product, through a kind of thermoplastic resin of the explained hereafter such as pre-treatment, polymerization, distillation.Petroleum resin because of source be petroleum derivative and gaining the name, it is low that it has acid number, and compatibility is good, the characteristics such as water-fast, resistance to ethanol and chemicals-resistant, has chemically stable to soda acid, and have the feature regulating viscosity and Heat stability is good.Petroleum resin are not generally used alone, but use together with other resin as promotor, conditioning agent, properties-correcting agent.
The method of the common C9 petroleum resin of industrial production mainly contains 3 kinds: catalyst polymerization, thermal polymerization and initiated polymerization method.Thermal polymerization technique is simple, and color of resin is shallow and bright, good product quality, but this method is only applicable to C 5 fraction, or produces low softening point resin; Initiated polymerization method products obtained therefrom is of light color and bright, and there is no a catalyzer remove problem, without waste water, but temperature of reaction is high, and the time is long, low conversion rate, and the softening temperature of product is lower; Catalyst polymerization advantage is that polymerization temperature is lower than 100 DEG C, and polymerization time is short, good product quality, can produce the product of various softening temperature, and shortcoming is that catalyzer cost is higher, and has corrosion to equipment, has waste residue to produce in technological process.
Oil-containing calcium powder is the solid that the powdery calcium hydroxide added in the N-process in petroleum resin production process filters out through plate and frame(type)filter press, at present, oil-containing calcium powder is directly used for low-grade antifouling paste etc., reduce the use value of petroleum resin, because the resin contained in oil-containing calcium powder and solvent many, loss is large.
Summary of the invention
For the defect existed in prior art, the object of this invention is to provide the technical process of reclaiming rosin products in a kind of oil-containing calcium powder produced from resin granulation process.
The present invention adopts following technical scheme:
Reclaim a technical process for rosin products in the oil-containing calcium powder produced from resin granulation process, concrete step is as follows:
1) the oil-containing calcium powder produced in petroleum resin production process is joined in the solvent oil produced in resin granulation process under the condition stirred, the add-on of oil-containing calcium powder is the 10-50% of solvent oil weight, stir speed (S.S.) is 150 revs/min, churning time 10-60min; The stirring rake stirred is upper, middle and lower three layers, for upwards to stir during stirring;
2) the suspension liquid plate and frame(type)filter press press filtration after step 1) being stirred, pressure 0.4MPa;
3) by step 2) after oil-containing calcium powder under-0.1MPa pressure, at 180 DEG C ~ 240 DEG C temperature dry 1 ~ 4 hour.
The invention has the beneficial effects as follows:
Present invention process is simple, and the resin liquid of carrying secretly in treated oil-containing calcium powder obviously reduces, and the rosin products rate of recovery is high, and the volatile organic compounds in calcium powder is also less, achieves utilization of waste material, more environmental protection, saving.
