CN101314050A - Long-acting solid aromatic agent - Google Patents

Abstract

The invention discloses a long-acting solid aromatic, which comprises isoparaffin, essence, pigment, and a plastic slow-release carrier. SEBS is adopted as the plastic slow-release carrier, so the excellent physical and chemical characteristics of the SEBS ensures that a product can contain more essence, which assures steady aroma releasing rate and obtains longer aroma releasing period and storage period. The long-acting solid aromatic overcomes the disadvantages that a solid aromatic product in the prior art has small spice containing amount of the carrier, bad weather resistance, weak ability for slow-release control, unsteady aroma releasing rate, short aroma releasing period and storage period and so on, and achieves the aims of long-lasting aroma releasing, good weather resistance, steady aroma releasing rate, and easy long-term storage.

Description

A kind of long-acting solid aromatic agent

Technical field

The present invention relates to a kind of daily chemical product, specifically be meant be applied in indoor, the car, aircraft cabin etc. all need remove a kind of long-acting solid aromatic agent that abnormal flavour improves the air odor place.

Background technology

The solid aromatic product of prior art such as publication number are the disclosed a kind of solid aromatic of the patent document of CN1174083A, the molten culvert amount of flavorants of its carrier little (5～6%), and the controlling slow release ability is released fragrant speed instability.Summer, heat was volatilized soon, and fragrance is strong; Winter is cold, and volatilization is slow, and fragrance is faint.Carrier can melt when summer temperature is hot, and fragrance runs off and quickens; During the winter temperature severe cold, it is dry and cracked to harden, and fragrance discharges faint.Simultaneously, other solid aromatic products of prior art also all exist to some extent, and the molten culvert amount of flavorants of carrier is little, and weatherability is poor, a little less than the controlling slow release ability, releases fragrant speed instability, release deficiencies such as perfume phase and storage period weak point.

Summary of the invention

The present invention is directed to the deficiency of the solid aromatic product of above-mentioned prior art, adopt the more essence of the molten culvert of energy, and it is heat-resisting cold-resistant, the technical scheme of the slow-released carrier that the sustained release rate under high temperature and low temperature is uniform and stable, provide a kind of long-acting solid aromatic agent, no matter be intended to reach spring, summer, autumn and winter, scorching summer and freezing winter, it is fragrant stable lasting all to release, and is easy to the purpose of long term store.

The object of the present invention is achieved like this: a kind of long-acting solid aromatic agent comprises isoparaffin, essence, pigment, plasticity slow-released carrier, wherein: described isoparaffin, optional kind has, different hendecane, Fancol ID, different tridecane, and amount ranges is 50～60%; Described essence is the oiliness compound essence, and optional odor type has, and floral type, Fruity type, Radix Aucklandiae type, hay-scented type, amount ranges are 10～20%; Described pigment is synthetic daily use chemicals pigment, and amount ranges is 0.0001～0.01%; Described plasticity slow-released carrier is SIS/SEBS (SEBS), and amount ranges is 30～40%.

Preparation technology: at normal temperatures and pressures, complex compounding forms by weight percentage;

Step 1: isoparaffin is added reactor, start blender, under agitation, slowly add the required essence of prescription, it is fully dissolved, slowly add the required pigment of prescription then, stir, make mixed solution;

Step 2: at normal temperatures and pressures, the required plasticity slow-released carrier of prescription is added another reactor, start blender, under agitation, the mixed solution that step 1 is made slowly adds in this reactor, stirs to make its abundant mix homogeneously;

Step 3: at normal temperatures and pressures, the mixture of step 2 poured in the extruder extrudes, make it mixing evenly.

In the prescription of the invention described above, adopt SEBS to make the plasticity slow-released carrier, because SEBS has UV stable preferably, antioxidation and heat stability, heat resistance preferably, its brittle temperature≤-60 ℃, maximum operation (service) temperature reaches 149 ℃, under oxygen atmosphere, its decomposition temperature has the fine solubility energy greater than 270 ℃, blend and excellent oil-filled property, can be dissolved in many common solvent, its solubility parameter between 7.2～9.6, can with the multiple polymers blend, make a kind of long-acting solid aromatic agent of the present invention can the more essence of molten culvert (20%), sustained release rate under high temperature and low temperature is uniform and stable, releases fragrant phase and storage period thereby obtain longer use.The full-scale investigation test result confirms: it releases fragrant phase and storage period, all above more than a times of like product of prior art.

Raw materials such as above-described isoparaffin, essence, pigment, plasticity slow-released carrier can both be buied from chemical reagent and Plastics Company, and its mechanism of action, chemical property, toxicity etc. are affiliated field common practise, and this paper does not give unnecessary details.

The feature of a kind of long-acting solid aromatic agent of the present invention is: adopt SEBS to make the plasticity slow-released carrier, with its excellent physicochemical property, make the more essence of the product molten culvert of energy of the present invention, guaranteed the stable fragrant speed of releasing, obtain longer releasing fragrant phase and storage period.

The present invention is by the technical scheme of above-mentioned molten culvert slow release prescription, and a kind of long-acting solid aromatic agent that provides has reached to use releases perfume lastingly, and good weatherability is released fragrant rate stabilization, is easy to the purpose of long term store.

The embodiment explanation

Below by specific embodiment, the present invention is described in further detail, the percentage ratio in the prescription is weight percentage; The those skilled in the art can make a kind of long-acting solid aromatic agent of own required odor type colour pattern, but should not be construed as any limitation of the invention with reference to the compound method of embodiment.

The specific embodiment

Embodiment: orange sandalwood type long-acting solid aromatic agent;

Equipment: reactor, blender, extruder, electronic scale, forcing press;

Environmental condition: room temperature, an atmospheric pressure;

Preparation procedure:

Step 1: isoparaffin is added reactor, start blender, under agitation, slowly add the required essence of prescription, it is fully dissolved, slowly add the required pigment of prescription then, stir, make mixed solution.

Step 2: at normal temperatures and pressures, the required plasticity slow-released carrier of prescription is added another reactor, start blender, under agitation, the mixed solution that step 1 is made slowly adds in this reactor, stirs to make its abundant mix homogeneously.

Step 3: at normal temperatures and pressures, the mixture of step 2 poured in the extruder extrudes, make it mixing evenly.

Step 4: according to trimmed size, with the acquisition thing of electronic scale with step 3, the branch of the weighing box of packing into flattens with forcing press, and packing is finished product.

The purposes usage:

Be used in indoor, the car, aircraft cabin etc. all need remove the place that abnormal flavour improves air odor, during use, open the lid.

Store:
