Abstract
The invention discloses mildewproof plastics and a preparation process, and the invention relates to the field of plastic material preparation. The mildewproof plastics comprise 1-2% of antimildew agents, 70-80% of resins, and 18-28% of plasticizers. The antimildew agent comprises 20% of phenol, 20% of copper 8-hydroxyquinoline, 30% of triethyltin chloride or tribulyltin chloride, 10% of hexaconazole, and 10% of penconazole. The resin comprises polyethylene or polypropylene. The plasticizer is phosphate ester. The preparation process comprises the following steps of: (1) mixing, that is, well mixing various raw materials of the antimildew agent, the resin, and the plasticizer in a mode of increasing with equal ratios; (2) plastication at a temperature of 200-280 DEG C with shearing time of 5 hours; (3) granulation.
Description
Technical field: the invention belongs to the plastic material preparation field.
Background technology:
Plastics were very stable originally, can be because of the mikrobe deterioration.But it in fact, also can suffer the infringement of mikrobe, as long as have temperature, humidity, these three key elements of nutrition, just is easy to become the hotbed of microbial reproduction.Therefore, the antibacterial and mouldproof technology of plastic prod becomes the focus of plastic production technology.
The plastics mould inhibitor is divided into inorganic and organic two types.In plastics mildew-resistant field, it is the most direct using the organic anti-bacterial mould inhibitor, the most effective, one of most economical means.But because the singularity of plastic industry, a lot of organic mould inhibitor and be not suitable for plastics on the market though the mould inhibitor that adds in the plastics is not high to cost requirement, have fabulous consistency, and can in the course of processing, keep high thermal stability.In addition, mould inhibitor also must can be moved to frosting, stops microbial attack and grows.Inorganic antimicrobial mildew preventive agent considers that from security and antibacterial effect ag material is used in exploitation mostly.From effect, better to common bacteria effect in the fungi.The problem that exists is an oxidant reaction in silver ions and the resin, the tawny phenomenon that causes because of the light and heat reduction reaction occurs.Receive the influence of coloring resin in this variable color, need suitably adjustment with dyeing pigment and dispersion agent.
Therefore, development of new plastics mould inhibitor, and the anti-mildew plastics that the novel plastic mould inhibitor is processed are extremely urgent.
The objective of the invention is to design a kind of in order to design a kind of mildew-resistant plastics and preparation technology.
Technical scheme of the present invention is: a kind of mildew-resistant plastics and preparation technology.Said mildew-resistant plastics are by the 1-2% mould inhibitor, the 70-80% resin, and the 18-28% softening agent is formed.Described mould inhibitor is by 20% phenol, 20%8-copper quinolinate, 30% chlorination, three second or tributyl tin, compositions such as 10% own azoles alcohol, 10% Topaze.Described resin is made up of Vilaterm or Vestolen PP 7052.Described softening agent is a phosphoric acid ester.Preparation technology comprises that (1) mix: with mould inhibitor, resin, softening agent according to the geometric ratio incremental manner with various raw material uniform mixing.(2) plasticate: temperature is 200-280 ℃, shear time 5 hours.(3) pelletizing.
The invention has the beneficial effects as follows:
The present invention prevents that mikrobe or mould from breeding on plastics, avoid the harm to food and clothes of mikrobe or mould.The present invention adopts composite mildew inhibitor to prepare the mildew-resistant plastics; Softening agent has used the SULPHOSUCCINIC ACID ESTER with anti-mildew function simultaneously, has reduced the consumption of various single mould inhibitors, and its advantage is: mildew-proof function is not only arranged; And consistency is preferably arranged with resin copolymer, have light, thermostability.
Practical implementation method of the present invention:
(1) with 2% mould inhibitor, 70% resin, 28% softening agent according to the geometric ratio incremental manner with various raw material uniform mixing.Temperature is 200-280 ℃, and shear time 5 hours is processed the thing of plasticating.The anti-mildew plastics are processed in pelletizing.
(1) with 2% mould inhibitor, 80% resin, 18% softening agent according to the geometric ratio incremental manner with various raw material uniform mixing.Temperature is 200-280 ℃, and shear time 5 hours is processed the thing of plasticating.The anti-mildew plastics are processed in pelletizing.
