Abstract
The invention relates to a waste rubber powder/polystyrene thermoplastic elastomer material and a preparation process thereof. The waste rubber powder/polystyrene thermoplastic elastomer material is prepared by blending the following components in parts by weight: 100 parts of polystyrene, 80-140 parts of waste rubber powder, 5-30 parts of compatilizers, 5-10 parts of phenolic resins, 5-15 parts of stearic acids and 5-10 parts of zinc oxide. The waste rubber powder/polystyrene thermoplastic elastomer material has the advantages of excellent performance, easy processing, environmental protection and low cost.
Description
Technical field
The present invention relates to a kind of thermoplastic elastic material and preparation technology thereof, especially relate to a kind of shoddy that mainly utilizes waste rubber tire to make/thermoplastic polystyrene elastomer material and preparation technology thereof.
Background technology
Along with the fast development of automotive industry, waste and old useless rubber tire also produces thereupon in a large number.
Waste rubber belongs to thermoset copolymer material, is difficult to degraded under field conditions (factors), abandon in the face of land or be embedded in the soil more than ten years all never degenerate, without putrefaction; The accumulation land occupation of waste rubber, contaminate environment influences residents ' health and fire hazardous.So the disposal of waste rubber goods has become the practical problems that various countries' environmental protection industry, rubber industry need to be resolved hurrily.And, show that according to data China is the big rubber of the first in the world country of consumption, be again the big rubber of the first in the world importer, rubber raw materials is originated and substitute material becomes very urgent task so seek.
The recycling project of waste rubber is listed in " Chinese 21st century agenda " scheme, and is listed in the field of giving priority to of recycling economy, so the research that waste old is recycled seems quite important.
The recoverying and utilizing method of existing waste rubber mainly is to adopt to pulverize the legal system vulcanized rubber powder, and this method is that collection environmental protection and resource regeneration are the quite rising mode of utilizing of one.
At present, vulcanized rubber powder is mainly used in the study on the modification of plastics, pitch and rubber.Wherein, utilizing shoddy and plastics to prepare thermoplastic elastomer, is a direction with researching value.But the consistency of shoddy and plastics and interface binding ability are relatively poor, thereby the thermoplastic elastomer poor performance that makes.
Summary of the invention
The objective of the invention is to overcome the above-mentioned defective that prior art exists, provide a kind of processing simple, cost is low, the shoddy of superior performance/thermoplastic polystyrene elastomer material and preparation technology thereof.
The objective of the invention is to be achieved through the following technical solutions:
The present invention's shoddy/thermoplastic polystyrene elastomer material is mixed by following component and weight part and makes:
100 parts of polystyrene;
80～140 parts of shoddies;
5～30 parts of compatilizers;
5～10 parts in resol;
5～15 parts of stearic acid;
5～10 parts in zinc oxide.
Described shoddy is mainly made by waste and used rubber tyre, particle diameter 40～100 orders.
Described compatilizer can be for being selected from one or more the mixture among polyisobutene-g-polystyrene, ethylene-vinyl acetate copolymer, ethene-alcohol copolymer, the carboxylic acid PS.
Described resol can be one or more the mixture that is selected from phenol formaldehyde resin, alkylphenol formaldehyde resin, the tert-butyl phenol formaldehyde resin.
The preparation technology of the present invention's shoddy/thermoplastic polystyrene elastomer material may further comprise the steps:
(1) shoddy was soaked in acetone 3～6 hours, drying, standby;
(2) polystyrene and compatilizer are placed the mill 3～5min that begins to pratise, 150～200 ℃ of mixing temperatures; The shoddy that adds then through step (1) immersion treatment continues mixing 3～5min; Add resol, stearic acid and zinc oxide afterwards, thin-pass 8-12 time, following sheet.
The present invention carries out pre-treatment to shoddy earlier, utilizes acetone to weaken rubber powder polarity, and itself and polystyrene consistency are improved greatly; Simultaneously, adopt compatilizer, reduce its interfacial tension the further increase-volume of rubber powder.Owing to still have unsaturated link(age) in the shoddy, cross-linking vulcanized by resol improved its performance greatly.It is simple that the present invention has processing, environmental protection, the advantage that cost is low.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail.
Shoddy of the present invention/thermoplastic polystyrene elastomer material embodiment composition of raw materials is listed in table 1.
Preparation: (1) places acetone to soak 3 hours shoddy, and drying is stand-by; (2) polystyrene and compatilizer are placed the mill 5min that begins to pratise, 180 ℃ of temperature; Add the modified waste rubber powder of handling through step (1) then, continue mixing 5min; Add resol, stearic acid and zinc oxide afterwards, thin-pass 10 times, following sheet.
The mechanical property of the shoddy of embodiment 1-5/thermoplastic polystyrene elastomer material the results are shown in Table 2 according to the test of ASTM prescriptive procedure.
