RU2512951C1 - Composition of mulching covering (versions) - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: composition of mulching covering contains lignosulfonate, carbamide, Na-carboxymethylcellulose, potassium chloride, and as natural additives moss of species Polytrichopsida and needles of larch Larix lubarskii, and water in wt %: lignosulfonate 0.1-0.4, carbamide 0.2-0.6, Na-carboxymethylcellulose 0.3-0.4, potassium chloride 1-3, moss of species Polytrichopsida 10-15, needles of larch Larix lubarskii 8-9, water - the remaining part. Quantity of larch Larix lubarskii needles in second and third versions of mulching covering constitutes in wt % respectively 9.1-9.5 and 9.8-11.

EFFECT: extension of arsenal of compositions for soil mulching.

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 mulching coating composition was known in which polyacrylamide, urea, lignosulfonate, potassium chloride and water were used, wt.%: 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, C09K 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 - mosses, various types of wood waste, bark, shavings, wood chips. 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 the present invention, the technical result is the use of numerous types of natural materials, that is, expanding 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 Polytrichopsida and needles of larch Larix lubarskii, water in wt.%:

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 Polytrichopsida 10-15 needles of larch Larix lubarskii 8-9 water rest.

As options, the following compositions were invented, in which important ratios for moss and needles were changed (selected):

moss of the species Polytrichopsida 10-15 needles of larch Larix lubarskii 9.1-9.5

or

moss of the species Polytrichopsida 10-15 needles of larch Larix lubarskii 9.8-11

The composition is prepared as follows.

These ingredients are individually milled and then mixed in an aqueous medium.

The table shows various examples for the variants of the invention:
