Abstract
The utility model relates to a wavy-section-type TPV (Thermoplastic Vulcanizate) particle. The section of the extruded particle is in a shape of a wavy structure, and the longitudinal width of the wavy section is identical. According to the wavy-section-type TPV particle, the end surface of the extruded TPV particle is in a shape of a wavy section by changing a mouth die of an extruder, and therefore the heat stability and the weather resistance of the extruded particle are improved. The TPV particle is simple in structure and convenient to machine; and the crystallization speed of the wavy-section-type TPV particle is improved, and thus the wavy-section-type TPV particle is convenient for injection molding.
Description
Technical field
The utility model belongs to chemical field, relates to a kind of particle of extruding of plastics, especially a kind of wave section type TPV particle.
Background technology
TPV Thermoplastic Vulcanizate (English is Thermoplastic Vulcanizate), claim the polyolefin alloy thermoplastic elastomer again, be meant that with styrenic elastomericss such as SBS, SEBS be the thermoplastic elastomer of base-material, consumption is big in civilian and terminal consumption product field is undivided for this and styrenic elastomerics.
TPV mainly is made up of two parts, and the one, plastics are as external phase, and the 2nd, rubber is as disperse phase, and rubber need cooperate with it with softening oil or softening agent usually.Vulcanizing agent and some auxiliary addition agents also are absolutely necessary.In order to reduce cost or to improve the performance of certain aspect, some mineral filler meetings are dosed in addition.
Can form TPV between many plastics and the rubber, present business-like have PP/PE/EPDM, PP/NBR, PP/ACM, PS/SEBS.Under the bigger situation of the polarity between plastics and the rubber or surface energy difference, add appropriate compatilizer, carry out dynamic vulcanization again, also can obtain the blend of excellent property.
Existing TPV particle is cylindrical, because the restriction of material character, granulation performance is not fine in process of production.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of thermostability and good weatherability is provided, is easy to the wave section type TPV particle that injection moulding is processed.
The present invention realizes that the technical scheme of purpose is as follows:
A kind of wave section type TPV particle, it is wavy shaped configuration that described this extruded the particulate section form.
And vertical width of described waviness section is all identical.
Advantage of the present utility model and positively effect are:
1, the utility model is by changing extruding dies, and making and extruding TPV particulate end surface shape is the wave section type, has strengthened and has extruded particulate thermostability and weathering resistance.
2, the utility model is simple in structure, easy to process, and the TPV particle of wave section type has improved the crystallization velocity of product, is easy to injection moulding processing.
Description of drawings
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view.
Embodiment
Describe present embodiment in detail below by accompanying drawing.Need to prove that present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model thus.
A kind of wave section type TPV particle, this shape of extruding particle 1 is referring to Fig. 1 and Fig. 2, and its section is a wavy shaped configuration.This is extruded particle and extrudes to add and adopt man-hour forcing machine to realize, and forms the waviness section by changing extruding dies, make the particle of extruding.
Vertical width of the waviness section of being made is all identical.
The utility model is by changing extruding dies, making and extruding TPV particulate end surface shape is the wave section type, has strengthened and has extruded particulate thermostability and weathering resistance, and it is simple in structure, easy to process, the TPV particle of wave section type has improved the crystallization velocity of product, is easy to injection moulding processing.
Claims (2)
1. wave section type TPV particle, it is characterized in that: it is wavy shaped configuration that described this extruded the particulate section form.
2. wave section type TPV particle according to claim 1, it is characterized in that: vertical width of described waviness section is all identical.
