Abstract
The invention discloses a method for preparing environmentally friendly adhesive. The method belongs to the field of chemical adhesive. The environmentally friendly adhesive is produced by a method of mixing raw materials under specific conditions, wherein the raw materials contain, by weight, 25-30% of liquid styrene-butadiene rubber, 50-55% of styrene, 8% of liquid melamine formaldehyde resin, 1% of an antioxidant RD, 5% of benzene, 2% of zinc oxide, 2% of phthalic acid diester and 2% of magnesium oxide. The product has excellent water resistance, weatherability, oil resistance and aging resistance, has high tensile strength and elasticity, especially has the outstanding advantage of heat resistance, has high bonding strength even at high temperature, and is widely applied in bonding of materials such as metal, polystyrene, timber, glass, glass paper and the like.
Description
Technical field:
The invention belongs to chemical field, relate in particular to a kind of method of preparing environment-friendly adhesive.
Background technology:
Product environment-friendly adhesive of the present invention is taking butadiene-styrene rubber as main material production, butadiene-styrene rubber can be divided into two kinds of emulsion polymerisation and polymerisation in solutions by polymerization classification, usually said butadiene-styrene rubber mainly refers to emulsion polymerized styrene butadiene rubber, emulsion polymerized styrene butadiene rubber comprises again the hot butylbenzene of high temperature emulsion polymerisation and the suddenly benzene of low temperature emulsion polymerisation, the hot butylbenzene production technology of high temperature emulsion polymerisation is eliminated, usually said butadiene-styrene rubber mainly refers to the butadiene-styrene rubber that low temperature emulsion polymerization is produced, it has higher wearability and very high tensile strength, good processing characteristics, and other combination property, its combination property is good, price is low, can replace natural rubber to use in most occasions, be mainly used in tire industry, automobile component, sebific duct, the goods of electric wire and adhesive. if liquid butadiene-styrene rubber directly uses as adhesive, because its polarity of chain is little, adhesive strength and adhesive property are all poor, must be through modification, in formula, add plasticizer and modifier, can greatly improve adhesive strength and the adhesive property of butylbenzene rubber-based adhesive. product of the present invention is exactly taking butadiene-styrene rubber as primary raw material, add plasticizer and modifier, to improve the adhesive strength of adhesive and to improve adhesive property, the Adhensive performance making is good, and there is good resistance to water, weatherability, oil resistivity, durability, and there are higher tensile strength and elasticity, particularly outstanding advantage is to have heat resistance, under higher temperature, still have higher adhesive strength, product is widely used in the bonding of the materials such as metal, polystyrene, timber, glass, glassine paper.
Summary of the invention:
The problem that the present invention mainly solves is: a kind of method of preparing environment-friendly adhesive taking liquid butadiene-styrene rubber as raw material is provided, and the raw material of producing this product use is by weight ratio: liquid butadiene-styrene rubber 25-30%, styrene 50-55%, liquid melamine formaldehyde resin 8%, anti-aging agent RD 1%, benzene 5%, zinc oxide 2%, phthalic acid two fat 2%, magnesia 2%.
The technical solution used in the present invention is:
(1) benzene of formula ratio is added to the first agitator tank, under normal temperature, add while stirring the anti-aging agent RD of formula ratio, stir stand-by;
(2) styrene of formula ratio is added to the second agitator tank, add successively liquid melamine formaldehyde resin resin, zinc oxide, phthalic acid two fat, the magnesia of formula ratio stand-by after stirring;
(3) the liquid butadiene-styrene rubber of formula ratio is added to chemical reaction kettle, while stirring temperature is brought up to 55-60 DEG C, material in the first agitator tank and the second agitator tank is sent into chemical reaction kettle simultaneously, after stirring, stop stirring after insulation reaction 1.0-1.2 hour, stir again and after 0.1-0.15 hour, stop stirring, obtain finished product after being cooled to normal temperature.
Further technical scheme of the present invention is:
The described insulation reaction time of step (3) is 1.1 hours, then mixing time is 0.125 hour.
The invention has the beneficial effects as follows: a kind of method of preparing environment-friendly adhesive is provided, this Adhesive technique is simple, raw material sources are abundant, product has good resistance to water, weatherability, oil resistivity, durability, and to have higher tensile strength and elasticity, particularly outstanding advantage be to have heat resistance, under higher temperature, still have higher adhesive strength, product is widely used in the bonding of the materials such as metal, polystyrene, timber, glass, glassine paper.
