Problems solved by technology

Yet there is seasonal problem in the production of this glue, and the white glue that uses polyvinyl alcohol (1799 type) to produce in winter will freeze and can't be used when there is less than 5 degrees Celsius
Some manufacturers use imported polyvinyl alcohol (type 1788 or type 217) to produce white glue in winter. Although it can solve the problem of frost resistance, the price of type 1788 or type 217 is much higher than that of type 1799.

Embodiment 1

[0035] This embodiment provides a general-purpose industrial glue, including the following raw materials in parts by weight: 40 parts of polyvinyl alcohol, 3 parts of formaldehyde, 2 parts of hydrochloric acid, 6 parts of sodium hydroxide, 2 parts of chain integrity agent, 400 parts of water, Vinyl acetate 3000 parts, OP-104 parts, dibutyl phthalate 36 parts, potassium persulfate 0.2 parts.

[0036] Preferably, the polyvinyl alcohol is 1799 type.

[0037] Preferably, the OP-10 is a nonionic surfactant alkylphenol polyoxyethylene ether.

Embodiment 2

[0039] The difference between this embodiment and Example 1 is that it includes the following raw materials in parts by weight: 45 parts of polyvinyl alcohol, 4 parts of formaldehyde, 3.5 parts of hydrochloric acid, 7 parts of sodium hydroxide, 2 parts of chain integrity agent, 500 parts of water, acetic acid Vinyl ester 360 parts, OP-105 parts, dibutyl phthalate 37.5 parts, potassium persulfate 0.6 parts.

Embodiment 3

[0041] The difference between this embodiment and Example 1 is that it includes the following raw materials in parts by weight: 40-50 parts of polyvinyl alcohol, 5 parts of formaldehyde, 5 parts of hydrochloric acid, 9 parts of sodium hydroxide, 2 parts of chain-integrating agent, 600 parts of water , 420 parts of vinyl acetate, 106 parts of OP-106 parts, 39 parts of dibutyl phthalate, and 0.8 parts of potassium persulfate.

[0042] Carry out experimental comparison with traditional glue according to above-mentioned embodiment, concrete comparative data is as table 1:

Abstract

The invention discloses a universal industrial glue. The universal industrial glue comprises, by weight, 40-50 parts of polyvinyl alcohol, 3-5 parts of formaldehyde, 2-5 parts of hydrochloric acid, 6-9 parts of sodium hydroxide, 2 parts of a whole chain agent, 400-600 parts of water, 300-420 parts of vinyl acetate, 4-6 parts of OP-10, 36-39 parts of dibutyl phthalate and 0.2-0.8 part of potassiumpersulfate. A technology in the production process is stable, and the product does not freeze at -3 to -5 DEG C; and the production cost of the product of the invention is lower than that of industrial glue produced from 1788 type polyvinyl alcohol.

Description

technical field [0001] The invention relates to the technical field of industrial glue, in particular to a general-purpose industrial glue and a preparation method thereof. Background technique [0002] Industrial glue is used in industry to connect the surfaces of homogeneous or heterogeneous objects with adhesives. The adhesive has the characteristics of continuous stress distribution, light weight, or sealing. Polyvinyl acetate emulsion, commonly known as white glue, is the most common industrial adhesive. Yet there is seasonal problem in the production of this glue, and the white glue that uses polyvinyl alcohol (1799 type) to produce in winter will freeze and can't be used when there is lower than 5 degrees Celsius. Some manufacturers use imported polyvinyl alcohol (type 1788 or type 217) to produce white glue in winter. Although it can solve the problem of frost resistance, the price of type 1788 or type 217 is much higher than that of type 1799. Contents of the inv...
