Abstract

FIELD: chemistry.

SUBSTANCE: mulching composition contains, wt %: lignosulphonate 0.1-0.4, carbamide 0.1-0.4, Na-carboxymethyl cellulose, potassium chloride -0.3-0.4, natural additives - Tetraphidopsida moss 10-15 and Juniperus virginiana Aureospicata juniper needles 8-9, and water - the balance. The amounts are reflected in different versions of the polymer-natural mulching compositions.

EFFECT: use of said compositions improves the environment.

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 known was the composition of the mulching coating, 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, 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 by the fact 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 Tetraphidopsida and needles of juniper Juniperus virginiana Aureospicata, water in the following wt.%:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 Tetraphidopsida moss 10-15 juniper needles Juniperus virginiana Aureospicata 8-9 water rest

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

Tetraphidopsida moss 10-15 juniper needles Juniperus virginiana Aureospicata 9.1-9.5

or

Tetraphidopsida moss 10-15 juniper needles Juniperus virginiana Aureospicata 9.8-11

The composition is prepared as follows.

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

The table presents various examples for the variants of the invention, while the water content in each example is the rest up to 100%:
