Description
Technical field
The present invention relates to PP base material primary coat paint field, be specifically related to a kind of PP base material bottom-coating composition and method of making the same.
Background technology
Polypropylene (PP) film is one of common heat-shrinkable film material, there is excellent resistance to chemical attack, the features such as resistance to gentle water resistance, protection against the tide, physical strength are high, good stability of the dimension, light weight, nontoxic, odorless, printing performance are good, are widely used in label printing, coating, cigarette, food pack, vacuum aluminum-coated, electrical condenser etc.But PP is the material of low-pole, ink is difficult to the surface being attached directly to PP plastics film, makes ink be easy to come off, affects quality product.Therefore need middle layer to play the effect connecting base material and ink, and fastness to be got well.
PP base material bottom-coating composition is the coating between PP base material and ink coating, and its effect impels ink to be attached to securely on PP base material.PP base material bottom-coating composition is also widely used in many aspects such as household electrical appliance, small item, senior toy, high Primary plateaus is reached in appearance in order to make its goods, need to carry out surface daub on a wall, and the surface energy of PP plastics is low, polarity is low, usually poor adhesive force, needs to carry out special processing.As: the method such as flame method, corona, corrosion, but above method is all complicated loaded down with trivial details, in order to reduce operation, people usually take PP base material bottom-coating composition and are coated on PP ground, and then brushing ink, this is a kind of effective ways, and is method that is convenient, economic, the paint that saves time, economizes.In packaging industry, because PP base material heatproof is low, high-temperature shrinkage is serious, and the PP base material bottom-coating composition therefore needed can be low-temperature fast-curing, meets the needs of large industrialized production line balance simultaneously.PP base material bottom-coating composition is as the coating between PP base material and ink coating, need, with PP base material and ink, all there is good fastness, domestic at present also do not have a kind of product can meet these requirements simultaneously, is therefore badly in need of a kind of PP base material bottom-coating composition product of exploitation.
Domestic PP film consumes PP amount of resin and is in the 3rd, and demand growth speed is in recent years very fast.Within 1998, this domain requirement amount is only 430,000 tons, and 2004 more than 1,100,000 tons.Estimate that the growth rate of demand in 2005 is about 15%.Therefore PP base material bottom-coating composition product also has very large economic worth.
Summary of the invention
For defect of the prior art, the object of this invention is to provide a kind of PP base material bottom-coating composition and method of making the same, the present situation of the PP film later stage base paint solve that current PP bottom coating is very expensive, market not having again performance suitable, provides a kind of PP base material bottom-coating composition of excellent property.
