Description of the invention (1) Technical scope The present invention relates to non-liquid, abrasive compositions containing particulate abrasives, which are suitable for use in hard The cleanliness of the surface. BACKGROUND OF THE INVENTION Hard surface cleaners containing abrasive particles have long been known. A typical composition comprises one or more surfactants in a solution and a plurality of abrasive particles dispersed therein. Surfactants used in liquid abrasive detergents include alkylbenzene sulfonates, sulfates of alcohols, ethoxylates of alcohols, alkylamidoethoxylates, fatty acid soaps, and secondary alkylsulfonates Acid salt. These surfactant compositions (along with the electrolyte) are commonly used to create suspension systems well known in the art. Solvents are well-known components of non-abrasive detergent compositions. Typical solvents used in detergent compositions include alcohols (such as ethanol), ethers (such as butyl cellosolve [TM]), stone ochers (such as Isopar L [TM]), esters, and terpenes (such as d-ningene). ). Another conventional solvent is alkanolamine. EP503219A (P & G) mentions a detergent composition containing from 01 to 10% of an alkanolamine. Non-liquid abrasive compositions are also known. It is in the form of a paste, gel and powder. It may contain a surfactant and may also contain a relatively low amount of water. Typical abrasives used in these compositions include calcite and dolomite. Description of the invention This paper is applicable to the Chinese National Standards (CNS). M Shuobai (210.X). 4 _ "

440603 Λ7 Η 7 V. Description of the invention (2) I found that the improved non-liquid abrasive detergent can be prepared by using a large amount of C2-C6 alkanolamines and electrolyte bases other than alkanolamines. The presence of alkanolamines is necessary because at elevated pH (because of the presence of bases) alkanolamines can be used as both solvents and bases to help remove difficult contaminants. Therefore, the present invention provides an abrasive cleaning agent which can effectively clean and is stable during storage. DETAILED DESCRIPTION OF THE INVENTION The present invention provides a non-liquid abrasive detergent composition comprising a) 50-99.5 wt% of one or more particulate abrasives, 100.5-15 wt% (: 2-(: 6alkanolamine) , C) at least 0.1% by weight of electrolyte bases other than alkanolamines, d) 0.1-20% by weight of one or more surfactants as needed, and Fill in the negative) Γ The Central Bureau of Standards of the Ministry of Economic Affairs of the People's Republic of China shall allow the cooperative to print 印 e) 0.1-20% by weight of solvents other than water or alkanolamines as required.

Description of the Invention (3) The particulate abrasive phase is composed according to the present invention The particulate phase preferably contains particulate abrasive that is insoluble in water. On the other hand, the abrasive may also be water-soluble and it is excessive for the water present in the composition so that the solubility of the abrasive in the aqueous phase exceeds The limit is therefore that solid abrasives are present in the composition. Suitable abrasives may be selected from particulate zeolites, calcite, dolomite, feldspar, silica, silicates, other carbonates, alumina, bicarbonates, borate, sulfates , And polymeric materials such as polyethylene. The preferred abrasives used in general-purpose compositions have a Mohs hardness of 2-6 and higher hardness abrasives can be used for special applications. For abrasives, a better average ( Weight average) particle size in the range of 0.5-400 microns, and about 10-200 microns is preferred. Within this range, good cleaning behavior and low substrate loss can be achieved. The preferred abrasive amount is 60-95% by weight of the product, and most preferably 65-90% by weight. The physical form of the product varies with the amount of abrasive present. A composition with a higher abrasive amount is usually a powder and a lower amount is usually a paste. When will a specific abrasive product change from a powder to a powder? The paste (when the amount of a particular abrasive is reduced) will be affected by the presence of other components. It can be seen from the preferred embodiment of the present invention described below that if the amount of abrasive is below 80-90% by weight, then The composition will become a paste. The physical stability of the paste can be improved by the presence of a high amount of abrasive. In this example, a high amount of abrasive refers to a content exceeding 80% by weight of the total composition. Best The abrasives are calcium carbonate (such as calcite), calcium carbonate, and magnesium carbonate. The paper size is applicable to the Chinese national standard (CNS) Λ4 坭 捎 (2I0X?

Calcite, feldspar, dolomite and their mixtures are the best because of low cost, suitable hardness and color. Alkanolamines Alkanolamines used in the composition of the present invention may have monofunctional or polyfunctional In terms of the hydroxyl moiety). The preferred alkanolamine is generally η2ν-κη where Ri is a straight or true branched chain having 2-6 carbon atoms. Preferred alkanolamines include: 2-amino-2-methyl-1-propanol, mono-, di-, and tri-ethanolamine, mono-, di-, and tri-isopropanolamine, dimethyl- , Diethyl- or dibutylethanolamine, and mixtures thereof. Salty cyclic alkanolamines (such as morpholine) can also be used. Particularly suitable alkanolamines include 2-amino-2-methyl-1-propanol, monoethanolamine, and diethanolamine. It is believed that these substances have an improved cleaning effect on hard or old dirt. And 2-amino-2-methyl-1-propanol (AMP) is the best among them. The typical content of alkanolamine in the composition of the present invention is 1-10% by weight. Higher levels are less suitable based on cost considerations and may also erode some plastics. The use of 2 to 6% by weight of 2-amino-2-methyl-1-propanol is the best choice.

Of course, hydroxides and other basic salts can also be used. Alkali metal carbonates are particularly suitable, while potassium carbonate is the best. _ The typical content of the electrolyte is 0.5-5% by weight, and the optimal electrolyte amount is 1-2.5% by weight. The pH of the composition should be increased above the pKa of the alkanolamine, and the increased pH is preferably higher than The alkanolamine has a pKa of at least one unit. A 50% by weight slurry of the water-forming composition is used to measure the pH to determine whether the pH has reached a desired level. In a composition containing a relatively low amount of abrasive, especially when the amount of abrasive is less than 75% of the product and / or the product is in the form of a paste, the electrolyte 尙 has another function. It is believed that as the amount of abrasive in the composition decreases, the composition gradually becomes less stable and the tendency of the composition to separate into two phases increases. Using potassium carbonate as the electrolyte and adding water to the composition can overcome this disadvantage. Among compositions containing potassium carbonate and water, feldspar is preferably used as the abrasive material. The ion exchange between Xianxin potassium carbonate and other better abrasive materials (especially dolomite) will gradually slow down the composition, thereby lowering the pH and ultimately reducing the effectiveness of the composition. Surfactant The composition according to the present invention preferably comprises a detergent active material, which is usually selected from anionic and nonionic detergent active materials. Surfactants and this paper size are applicable to the Chinese National Standard (CNS) Λ4ίΓ grid (210X? ㈤S 1 7〇 ~. ··· * a count first read back and note #review item then fill in β page) Printed by Yu-Ministry's Central Bureau-T-Consumer Cooperatives-9- 440608 Λ7 __H7 V. Invention Description (6) is not a necessary component of the composition, but can provide a foaming effect (which is usually expected by users And it has extra cleaning effect on some dirt). In some cases, the presence of a surfactant can aid the construction of the product. Suitable anionic detergent active compounds are water-soluble salts of organic sulfuric acid reaction products. The molecular structure of these reaction products has an alkyl group containing 8 to 22 carbon atoms, and is selected from the group consisting of a sulfonic acid group or a sulfate group and Groups of the mixture. Examples of suitable anionic detergents are the sodium and potassium salts of alcohols, especially those obtained by the sulfation of high-carbon alcohols, which are obtained by reducing the fatty oil or glycoside esters of coconut oil; alkylbenzenes Sodium and potassium sulfonates such as those in which the alkyl group contains 9 to 15 carbon atoms; sodium and potassium secondary alkane sulfonates; sodium alkylglycoside ether ethers, especially ethers derived from the higher alcohols of fatty and coconut oils ; Coconut oil fatty acid monoglycoside sodium sulfate; Sodium and potassium salts of sulfate esters of reaction products of one mole of high-carbon fatty alcohols with 1 to 6 moles of ethylene oxide; alkylphenol oxide vinyl ether sulfate (which has 1 to 8 units of ethylene oxide molecules in which the alkyl group contains 4 to 14 carbon atoms) sodium and potassium salts; reaction products of fatty acids esterified with 2-hydroxyethanesulfonic acid and neutralized with sodium hydroxide Derived from coconut oil and mixtures thereof. Preferred water-soluble synthetic anionic detergent active compounds are high-carbon alkylbenzene sulfonates and their mixtures with enoisylate and sulfonyl alkyl sulfates, and high-carbon fatty acid monoglycol sulfates. Alkali metal (such as sodium and potassium) and alkaline earth metal (such as calcium and magnesium) salts. The most preferred anionic detergent active compound is a high-carbon alkyl aromatic sulfonate such as a high-carbon alkylbenzene sulfonate. The straight or branched alkyl group contains 6 to 20 carbon atoms. Specific examples are High carbon novolak benzoate or local carbon noxyl toluene, xylene or osmium salt

Advantages of the invention (1). I have also learned that terpene materials have better performance at pH values below 11. The amount of linear paraffin can be higher than that of terpenes because these materials are less likely to attack plastics. Salt letter paraffin will have better performance at a pH higher than 11. Glycol ether is better than other solvents. Its typical amount is 5-10% by weight of the product and diethylene glycol mono-n-butyl is used. Ether is best. The ratio of alkanolamine to solvent preferably falls in the range of 3: 1-1: 3, and the ratio is most preferably 1: 1 to 1: 3. It is a better practice to introduce a part of the solvent in the form of a perfume component, although the amount of solvent required usually requires the addition of a higher amount of this component (which is usually used in perfume compositions as a perfume component). Type exists). Terpenes are best used in this way because the terpenes (such as nysene) used have a pleasant citrus flavor, while the ocher and glycol ethers usually have no flavor. Rheology and construction agents The composition of the present invention as described above may be a paste, a gel or a powder. Suitable rheology control agents can be used especially when the composition contains a large amount of water or a low viscosity surfactant. These control agents include wrought silica and clay.

I have found that 1-2% by weight of wrought silica is sufficient to stabilize the paste. Aerosil 380 (TM) is a suitable builder D. We have also found that the addition of 1-8¾ of water is sufficient to stabilize the easily separated composition.

Α7 Β7 V. Description of the invention (19) It should be noted here that even if a hydrated salt is used, water needs to be added in order to thicken the sample (when a low amount of carbonate is used). Example 5: Use of different abrasives First measure the 50% slurry of Example P2 and have a pH of 2% water, and then a few weeks later, prepare a new slurry and measure its pH. It is known that the pH of a water-containing sample decreases after a few weeks. • T -9 changed the abrasive of P2 to feldspar (potassium aluminosilicate). Add 2% water to a sample and / measure pH as above. The pH of the first two samples was 11.9. The pH of the water-free sample after 10 days was 11.7, while the pH of the water-containing sample was 11.8. There is therefore no decrease in pH. Example 6: Foaming An example having the formulation of Table 7 was prepared. The foaming performance of the evaluation examples is shown in Table 8.
