1. a kind of dust-proof wood moulding guardrail, it is characterised in that: dust-proof wood moulding guardrail accounting by weight includes: that the plant of drying is fine Tie up 50~70%, antistatic agent 13~18%, maleic anhydride 3~6%, antioxidant (1010) 0.1~0.5%, polypropylene surplus.

2. the processing method of dust-proof wood moulding guardrail described in claim 1, it is characterised in that: the method successively include step such as Under:

The pretreatment of S1 plant fiber:

Plant fiber is eluriated completely with water, stirs soaked plant fiber 10~15 minutes, drainage, then at 80~90 DEG C At a temperature of be dried for standby；

S2 adds antistatic agent:

By polypropylene and antistatic agent 110~150 DEG C at a temperature of be mixed 2~3 hours so that the antistatic agent exists Fully dispersed in polymer, the antistatic agent is sodium alkyl sulfonate；

S3 mixing:

Plant fiber and S2 step that S1 step has pre-processed are mixed with the mixed with polymers of antistatic agent, and addition is added Agent is stirred 20~30 minutes under the conditions of 120~160 DEG C of closed environment, is sufficiently mixed and is uniformly obtained Wood-plastic material slurry；It is described Additive includes: maleic anhydride, antioxidant (1010)；

S4 is granulated:

By the Wood-plastic material slurry extruding pelletization in S3 step；

S5 molding:

Pellet after extruding pelletization is put into hot-forming in hot pressing die, obtains wood moulding guardrail finished product.

Technical field

The present invention relates to Wood-plastic material production technical field more particularly to a kind of dust-proof wood moulding guardrail and its processing methods.

Background technique

Wood moulding, i.e. wood plastic composite are a kind of advanced composite material (ACM)s being surging forward in recent years both at home and abroad, refer to and utilize poly- second Alkene, polypropylene and polyvinyl chloride etc. are mixed into instead of common resin adhesive with the useless plant fiber such as wood powder, rice husk, stalk New wood materials；Wood plastic composite includes plastics, thus has preferable elasticity modulus；Further, since including fiber is simultaneously Through being sufficiently mixed with plastics, thus have with the physical mechanical properties such as the comparable resistance to compression of hardwood, counter-bending, and its durability is bright Aobvious to be better than common wood materials, surface hardness is high, usually the 2~5 of timber times.

The guardrail built in current many mountain forest scenic spots, park gradually starts using Wood-plastic, and the present invention is to traditional wood Modeling guardrail improves, and improves the anti-dust performance of wood moulding guardrail, and palm contamination dust influences mood when tourist being avoided to help guardrail.

Summary of the invention

In view of the deficiencies of the prior art, the present invention provides a kind of dust-proof wood moulding guardrail and its processing methods.

The present invention is realized by following technological means solves above-mentioned technical problem:

A kind of dust-proof wood moulding guardrail, dust-proof wood moulding guardrail accounting by weight include: drying plant fiber 50~ 70%, antistatic agent 13~18%, maleic anhydride 3~6%, antioxidant (1010) 0.1~0.5%, polypropylene surplus.

The processing method of the dust-proof wood moulding guardrail successively comprises the following steps that

The pretreatment of S1 plant fiber:

Plant fiber is eluriated completely with water, stirs soaked plant fiber 10~15 minutes, drainage, then 80~90 It is dried for standby at a temperature of DEG C；

S2 adds antistatic agent:

By polypropylene and antistatic agent 110~150 DEG C at a temperature of be mixed 2~3 hours so that the antistatic Agent is fully dispersed in polymer, and the antistatic agent is sodium alkyl sulfonate；

S3 mixing:

Plant fiber and S2 step that S1 step has pre-processed are mixed with to the mixed with polymers of antistatic agent, and is added and adds Add agent, stirred 20~30 minutes under the conditions of 120~160 DEG C of closed environment, is sufficiently mixed and uniformly obtains Wood-plastic material slurry；Institute Stating additive includes: maleic anhydride, antioxidant (1010)；

S4 is granulated:

By the Wood-plastic material slurry extruding pelletization in S3 step；

S5 molding:

Pellet after extruding pelletization is put into hot-forming in hot pressing die, obtains wood moulding guardrail finished product.

The present invention has the advantages that

(1) compared with prior art, the present invention is dispersed in preparation wood moulding shield as antistatic agent using sodium alkyl sulfonate In the polymer on column, so that the wood moulding guardrail produced contains surfactant, the surfactant penetrates into wood moulding guardrail Surface forms a smooth surfactant molecule layer, so that wood moulding guardrail skin-friction coefficient reduces, friction generates electrostatic Probability reduce；The hydrophilic radical that surfactant molecule layer arranges outward simultaneously absorbs the micro-moisture in environment, described micro- It measures water adsorption and forms conductive layer on wood moulding guardrail surface, the sheet resistance of wood moulding guardrail is effectively reduced, so that wood moulding guardrail table The charge in face is difficult to gather, to achieve the effect that antistatic, avoids the dust in wood moulding guardrail surface electrostatic absorption environment, So that palm will not be infected with dust when tourist helps guardrail；

(2) be built in mountain forest scenic spot, the wood moulding guardrail in park nearby often has large stretch of woods, air humidity is high, is conducive to Wood moulding guardrail surfactant molecule layer absorbs moisture to environment, so that wood moulding guardrail surface keeps micro- profit, good hand touch；And wood moulding Guardrail remains wet and improves flame retardant property, reduces a possibility that wood moulding guardrail is ignited.
