RU2497918C1 - Soil surface mulching composition (versions) - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: invention relates to compositions for mulching different types of soil, lawn and parking areas. The mulching composition is characterised by that it contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Sphagniidae moss and Pinus sylvestris pine needles, shells of Siberian pine nuts Pinus sibirica and Pinus sylvestris pine bark chips in the following ratios, pts.wt: lignosulphonate 0.1-0.4; carbamide 0.2-0.6; Na-carboxymethyl cellulose 0.3-0.4; potassium chloride 1-3; Sphagniidae moss 10-15; Pinus sylvestris pine needles 8-9; shells of Siberian pine nuts Pinus sibirica 4-6; Pinus sylvestris pine bark chips 2-5.

EFFECT: invention widens the range of soil mulching compositions.

Description

The invention relates to the chemistry of synthetic substances - polymeric mixed with organic and natural substances, for example, for urban and agricultural purposes or - to compositions for mulching various types of soils, lawns, park areas.

Previously, such a composition of the mulching coating was known in which polyacrylamide, urea, lignosulfonate, potassium chloride and water were used, in the following mass% ratio: polyacrylamide 0.25-0.75, lignosulfonate 0.5-1.5, carbamide 0.4 -0.8, potassium chloride 1-3, water the rest (Russian patent No. 2034899 C1, 1995, class of international classification of patents, С09К 17/00).

But such a patent did not use natural materials - this is a significant drawback. In nature, there are many materials suitable for this - many mosses, different types of wood waste, bark, shavings, wood chips, nutshells. Moreover, different types of wood can be combined with different types of synthetic materials - polymers, their waste - if they are harmless to the environment.

In this invention, the technical result is the use of numerous types of natural materials, that is, the expansion of the arsenal of compositions for mulching soils.

This result is achieved in that the composition of the mulching coating according to the invention contains lignosulfonate, urea, NA carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Sphagniidae, pine needles Pinus sylvestris, pine nutshells of Siberian cedar Pinus sibirica and wood chips Pinus sylvestris on the trail. parts by weight:

The composition of the mulch coating is characterized by the fact that it contains lignosulfonate, carbamide, Na-carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Sphagniidae, pine needles Pinus sylvestris, pine nutshell shells of the Siberian cedar Pinus sibirris Pinus sylris Pinus sylris pinus and bark chips. parts by weight:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 moss of the species Sphagniidae 10-15 pine needles Pinus sylvcstris 8-9 pine nutshell Siberian cedar Pinus sibirica 4-6 Pinus sylvcstris pine bark chips 2-5

The composition of the mulch coating is characterized by the fact that it contains lignosulfonate, carbamide, NA carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Sphagniidae, pine needles Pinus sylvestris, pine nutshell shells of the Siberian cedar Pinus sibirvest pinus sylvestris and bark chippings. parts by weight:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 moss of the species Sphagniidae 15-20 pine needles Pinus sylvestris 6-8 pine nutshell Siberian cedar Pinus sibirica 0-12 Pinus sylvestris pine bark chips 5-8

The invention is illustrated by the following examples:

Example 1

lignosulfonate 0.2 urea 0.35 Na-carboxymethyl cellulose 0.35 potassium chloride 2 moss of the species Sphagniidae 12 pine needles Pinus sylvestris 7 pine nutshell Siberian cedar Pinus sibirica 5 Pinus sylvestris pine bark chips 6

Example 2

lignosulfonate 0.3 urea 0.5 Na-carboxymethyl cellulose 0.4 potassium chloride 2,5 moss of the species Sphagniidae 17 pine needles Pinus sylvestris 8 pine nutshell Siberian cedar Pinus sibirica eleven Pinus sylvestris pine bark chips 3

Examples 3-10 are similar to 1, 2, but for extreme values showed that the technical result is achieved in the entire range of values.
