specific Embodiment 1

[0020] Specific embodiment 1, a kind of preparation method of white latex, comprises following raw material: polyvinyl acetate, polyvinyl alcohol, dibutyl phthalate, octanol, ammonium persulfate, water, the preparation method of described white latex Include the following steps:

[0021] (1) Stir 4kg of dibutyl phthalate and 1.5kg of octanol to dissolve the dibutyl phthalate;

[0022] (2) Add 45kg of water to the container and heat it up to 70°C, add 5kg of polyvinyl alcohol under stirring, raise the temperature to 90°C, and keep warm until completely dissolved;

[0023] (3) After dissolving, stop heating to lower the temperature to 68°C, and add 45kg of polyvinyl acetate under stirring;

[0024] (4) Add the solution prepared in step (1) into the solution prepared in step (3), and finally add 0.4 kg of ammonium persulfate, stir and mix evenly, and carry out emulsion polymerization at 68°C.

[0025] In the above steps, polyvinyl acetate is a water-based non-flammable and ex...

Abstract

The invention discloses a manufacture method of white latex, which is composed of the following raw materials and components: 40-50 parts of poly(vinyl acetate), 3-6 parts of poly(vinyl alcohol), 3-5 parts of dibutyl phthalate, 0.5-2 parts of octanol, 0.1-0.5 part of ammonium persulfate and 40-50 parts of water. The manufacture method comprises: dissolving dibutyl phthalate in octanol, dissolving poly(vinyl acetate) in a 66-69 DEG C poly(vinyl alcohol) solution, mixing the above two solutions, then adding ammonium persulfate, and carrying out emulsion polymerization. In the manufacture method, non-toxic, odorless and non-corrosive poly(vinyl acetate) is used to replace toxic and irritant vinyl acetate, so that the white latex is safer and more healthy for human bodies and is a pollution-free environmentally-friendly product.

Description

technical field [0001] The invention relates to a method for making glue, in particular to a method for making white latex. Background technique [0002] White latex is currently one of the most widely used and most used adhesive varieties. It is widely used in wood processing, architectural decoration, printed matter binding, leather, textile, paint and other industries. Traditional white latex mostly uses vinyl acetate and polyvinyl alcohol as the main raw materials. The polymerization process is complicated, the production cycle is long, and the product cost is high. Vinyl acetate: also known as vinyl acetate, vinyl acetate, referred to as vinyl acetate, a colorless flammable liquid with a strong fragrance. Insoluble in water, soluble in most organic solvents. For the system of vinyl resin and synthetic fibers. Also used in rubber, paint, adhesives, etc. Since vinyl acetate has low toxicity and strong odor, its vapor is irritating to the eyes, skin, mucous membranes a...
