Abstract
The invention provides a short-oil-length alkyd resin and a matte varnish utilizing the short-oil-length alkyd resin as a key film-forming material. The oil length of the short-oil-length alkyd resin is 30% to 30.5%, and when the matte varnish is in synthesis, part of ethylene glycol is added to adjust functionality so a to achieve the goal of improvement of molecular weight. The matte varnish solves the problem that a traditional short-oil-length alkyd resin coating often grows dim and is scratched easily in autumn and winter seasons.
Description
Technical field
The present invention relates to a kind of Synolac and with the clear finish of said alkyd resin production, relate in particular to a kind of short oil-ity alcohol acid resin and with the matte varnish that do not grow dim of said short oil-ity alcohol acid resin preparation.
Background technology
Synolac is the relatively low polymkeric substance of a kind of molecular weight, and the esterification through polyprotonic acid and polyvalent alcohol makes, and carries out modification with grease or lipid acid.In air dried process, can carry out oxidation to unsaturated fatty acids, thereby form cross-linked network.
Along with skyrocketing of oil price; And the worsening shortages of the energy, oil is relied on less phthalic resin coating demonstrate its meliority day by day, and; Along with the restricted rules about the VOC discharging constantly increase; The alkide resin emulsion used water substitutes organic solvent, thereby can be used as a kind of effective tool of the VOC of reduction content, has been widely used at present to produce high-quality decorative paint.
Phthalic resin coating itself does not exist the many shortcomings on the performance, and is high like hardness of paint film, drying property is poor.The oil content of Synolac has very big influence to performance, and Synolac oil content is short more, and second-order transition temperature is high more, and is fast more to the release of solvent, and drying property is good more, and protect light tint retention ability better.The Synolac that therefore present coating is used is short oil-ity alcohol acid resin, and especially oil content is at the short oil-ity alcohol acid resin more than 31%.
But the practice through for many years finds that the short oil-ity alcohol acid resin that uses at present changes over to after autumn and winter season every year, and the scuffing phenomenon of growing dim all appears in the furniture surface of a lot of furniture manufacturers easily; Tracing it to its cause is every autumn and winter season, and temperature reduces significantly, and particularly the region following the line of the sea is influenced by the ocean; Atmospheric moisture is than higher, and when under this low temperature and high humidity environment, constructing, the paint film temperature reduces rapidly with solvent evaporates; Cause moisture in the high humidity environment to condense into steam rapidly and invest coating surface; Because envrionment temperature is low, be easy to reach the freezing point of water, so the moisture in the paint film is difficult to volatilization in the drying process; Long term causes uneven drying even in paint film, and causes paint film grey hair flower and scuffing easily.And, the phase reversion phenomenon can appear during the phthalic resin coating solvent evaporates, and the paint film that causes forming no longer has homogeneity.
Summary of the invention
The invention provides a kind of new Synolac and the phthalic resin coating that uses said alkyd resin production; Utilize special short-oil alkyd to adjust paint film and do speed; Make the paint film top layer stable rapidly; Let the water function paint film time shorten, the easy problem that scratches thereby solution traditional alkyd resins coating grows dim.
