In the household often required glue for repairs. in DIY stores buying the right tools are not always pleased with price - performance ratio. Easier and more reliable to make a homemade glue Styrofoam. Simple recipe will open small secrets: how and what to dissolve the foam to create a viscous sticky mass.
The use of household glue
Before you start cooking homemade tools you need to understand what items can be glued together, and for what materials it is not necessary.
A successful connection will be only rigid objects, as adhesive mass hardens, reinforcing the strength of the product. Seal the crack in rubber boots, flexible on a break, homemade remedies will not work.
A feature of the use of glue is limited its application time - 10-15 minutes after cooking, after the adhesive mass quality decreases.
Therefore, a means is required in cases of small and urgent works:
- sealing joints of the fiberboard;
- repair floor, roof of tile or slate;
- gluing furniture, baseboards, interior;
- sealing cap;
- fixing the eaves;
- insulation of loggias, balconies, ceilings and floors, foundations, walls extruded polystyrene.
Owners of garages, garden houses, private houses are not just rescue the economy in a simple and quick to prepare homemade glue instead of expensive casein, joinery.
Necessary materials
In the manufacture of household adhesive requires only two major ingredients: a foam and an organic solvent.
Styrofoam
Zealous owners know where it is always possible to find various pieces of foam:
- in packaging boxes out of modern devices - used as shockproof means during transportation;
- residues sheet material (scraps or chips) used as a heater during the decoration;
- old Styrofoam trays, plates, cups - are widely used in the past.
It is interesting - how to cut foam. A detailed article.
Foam quality is different, as this term is called an entire group of materials obtained by different methods of foaming starting material. There are 4 varieties of foam:
- bespressovy - products from a plurality of interconnected balls. While pressing the material crumbles;
- a pressing - dense product with improved strength;
- extrusion - with a solid material structure;
- Granular - the loose material consisting of many small grains.
Before preparing samples of different types of foam can be immersed in gasoline for comparison. A good result will reflect the most efficient dissolution and bespressovogo granular material.
Important to note that the foam adhesive is needed for homemade pure without additives fire without having a specific smell.
Solvent
In the farm there is always a solvent. In the preparation of the adhesive can be used safely:
- acetone;
- Diluent nitrokrasok;
- refined petrol "Shoe";
- gasoline:
- Vietnamese gasoline (with the addition of acetone).
Not suitable grades of petrol with an increased content of fuel alcohol additives. It is not recommended to dissolve dichloroethane, benzene, toluene - a substance with a high toxicity of aromatic hydrocarbons. Although they belong to the best solvents, inhalation of fumes in the process of mixing leads to poisoning.
Equipment
Further ingredients for the preparation of the adhesive need to:
- Capacity. The first portion may be diluted even in an ordinary bowl or jar. A large amount of adhesive mass is convenient to breed in a metal canister.
- Gloves.
- Fan. During mixing the components allocated gases (Freon, styrene, etc.) Who inhale not recommended.
cooking recipes
There are two basic recipe, which is used by experienced handyman.
The first method is the following step-by-:
- to prepare a container for mixing ingredients - it should be clean, dry volume depends on the desired weight of the adhesive;
Main article: how and what to paint foam?
- pour a solvent in the necessary amount of adhesive mass;
- put the shredded pieces of foam or pellets in the amount of three times more than the solvent;
- Stir gently to remove the released gases;
- add pieces of foam or solvent if necessary.
The adhesive mass is ready to use when it becomes homogeneous, the consistency resembles thick jelly, ceases to give off gas.
Bonding parts should begin immediately. Weight applied with a brush. After drying glue joints resemble glass.
The second method is characterized in that the ingredients are combined in situ sealing gap. Proceed as follows:
- shredded foam to fill the crack, indentation, which is necessary to stick;
- moisten solvent - benzene or acetone;
- uniformly distribute the weight of the melting surface portion to be repaired.
Incorporation slits second method has a high degree of sealing, is often used in work with roofing material, roofing material by gluing.
It is important to prepare a sufficient amount of pre-foam to form a viscous adhesive mass. If the composition to produce a liquid, bonding will be ineffective.
Drying adhesive lasts depending on the layer thickness of 1.5-2 days.
Safety regulations
The use of foam adhesive requires compliance with fire safety regulations, because the mixture quickly ignited, burning a long time. Even a lit match could cause a fire. Mass upon heating releases a significant amount of heat and forms a dense black smoke.
for the manufacture of an adhesive operation is preferably carried out in the open air, so as not to harm health inhalation allocated vapors, gases foam when mixed with gasoline or another solvent.
A method for the preparation of adhesive materials that can be found in any house, practical and simple. Observance of simple rules will help to safely, quickly and inexpensively perform current repair work.
