SU670602A1 - Mastic for adhesive joining of plastic with wood materials - Google Patents

Description

one

The invention relates to the field of manufacturing polymer mastics for gluing plastics, for example, polyvinyl chloride plastic, plastic compound with metal, wood, concrete, for gluing acid-resistant ceramic tiles with concrete, wood, as well as for sealing joints between elements of wooden and concrete structures.

Mastics are known for bonding plastic and wood materials based on indene marmarone resin and rubber and based on indene marmarone resin and polystyrene 1 and 2.

Known mastics include scarce and expensive ingredients.

The closest to the technical essence and the resulting positive effect of the invention is a mastic for gluing plastic and wood materials containing perchlorovinyl resin and solvents - acetone, ethyl acetate, toluene and gasoline 3.

However, such mastic does not provide sufficient adhesion and frost resistance.

The purpose of the invention is to increase adhesion and frost resistance.

The goal is achieved by the fact that the proposed mastic for gluing rubber and wood materials,

including perchlorovinyl polymer, acetone, ethyl acetate, toluene and gasoline, contains as perchlorovinyl polymer waste perchlorovinyl fabric containing 93-95% perchlorovinyl and additionally ethylcellulose with an ethoxy ratio of 35-50%, ethyl alcohol and kaolin at the following, see the ratio of components, weight. %: Perfluorine vinyl cloth21 -25

The spent tissue (chlorinated tissue) is formed after it is used as a filter for calcium carbonate, calcium hydroxide, emulsifier, persalt and others, as well as in ventilation systems. The degree of wear of the fabric - 1-3%. Tissue waste (waste chlorinated tissue) contains 93-95% perchlorovinyl polymer and salts of iron, calcium, magnesium, and calcium hydroxide 5-7 wt. %

Example 1 (control). Mastic is prepared as follows. Waste chlorine tissue with a moisture content of not more than 0.5 wt. % and acetone and ethyl acetate are added, stirred to dissolve, toluene is added and the kaolin is poured in, stirring until a homogeneous mass.

Mastic is prepared as follows. Waste chlorine tissue with a moisture content of not more than 0.5% is placed in a flask with a stirrer, and acetone, ethyl acetate, and toluene are added. Cover tightly and mix until dissolved. In another container, ethylcellulose is dissolved in an alcohol-toluene mixture and 1: 4, the remaining portion of toluene and gasoline are added. This mixture is poured into the flask and the kaolin is poured into the working mixer. Stir until smooth.

As follows from the table, the proposed mastic is frost-resistant at temperatures up to -40 ° C, has a high adhesion to various materials, especially vinyl plastic to steel.

Mastic is characterized by reduced

cost due to the use of waste

production of chlorine tissue. Mastic

can be used in chemical,

construction and other industries of industry for gluing plastics, plastics with metal, wood, concrete, acid-resistant tiles with concrete, wood, for sealing joints between elements of wooden and concrete structures.
