RU2497927C1 - 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 contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Pellia endiviifolia moss and Larix kamtschatica larch needles, and water in the following ratios, wt %: lignosulphonate 0.1-0.4, carbamide 0.2-0.6, Na-carboxymethyl cellulose 0.3-0.4, potassium chloride 1-3, Pellia endiviifolia moss 10-15, Larix kamtschatica larch needles 8-9, water - the balance. Other versions of the polymer-natural mulching composition are also disclosed.

EFFECT: wider range of soil mulching compositions.

Description

The invention relates to the chemistry of synthetic substances - polymeric in mixture 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 known was the composition of the mulching coating in which polyacrylamide, urea, lignosulfonate, potassium chloride and water were used in the following ratio, wt.%: Polyacrylamide 0.25-0.75, lignosulfonate 0.5-1.5, urea 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 - many 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 environmentally friendly.

In the 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 by the fact that the composition of the mulch coating according to the invention contains lignosulfonate, urea, Na-carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Pellia endiviifolia and larch needles Larix kamtschatica, 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 species Pellia endiviifolia 10-15 needles of larch Larix kamtschatica 8-9 water rest

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

moss species Pellia endiviifolia 10-15 needles of larch Larix kamtschatica 9.1-9.5

or

moss species Pellia endiviifolia 10-15 needles of larch Larix kamtschatica 9.8-11

The composition is prepared as follows.

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