RU2497899C1 - Mulching composition (versions) - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry of synthetic substances - polymer substances in a mixture with organic and natural substances, for example, for urban and agricultural purposes, or 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, Sphaerocarpus moss and Larix ochotensis 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, Sphaerocarpus moss 10-15, Larix ochotensis larch needles 8-9, water - the balance. Also disclosed are other versions of polymer-natural mulching compositions in which the quantitative content of the needles is changed.

EFFECT: wider 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 mulching coating composition was known 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 harmless to the environment.

In my 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 Sphaerocarpus and needles of larch Larix ochotensis, water in the wake. wt.%:

Lignosulfonate 0.1-0.4 Urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 Sphaerocarpus moss 10-15 needles of larch Larix ochotensis 8-9 water rest.

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

Sphaerocarpus moss 10-15 needles of larch Larix ochotensis 9.1-9.5

or

Sphaerocarpus moss 10-15 needles of larch Larix ochotensis 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:
