Abstract
A new process for directly melting fiber-reinforced thermoplastic composite material relates to a new technology for forming the fiber-reinforced thermoplastic composite material. The technical proposal of the invention combines the process of directly melting and dipping the fiber-reinforced thermoplastic composite material with a molding process, and directly melts the thermoplastic resin and accessories and adds the molten materials to a mould for one-step molding. The proportions of the raw materials are as follows: 50-65% of acrylic resin, 28-35% of glass fiber, 0.5-2.0% of silicane coupling agent particles, 0.5-1% of bismaleimide, 0.05-0.1% of ultraviolet absorbent, 1-2% of antioxidant and 5-8% of packing. The specific process comprises batching, heating for soaking, press molding and demolding to obtain the blank of the fiber-reinforced thermoplastic composite material. The process has the advantages of forming by only one single heating process with low energy consumption; reducing intermediate links of batching storage, transport, preheating and the like, reduced energy consumption and manpower, lower production cost, high degree of batching freedom and small fiber attrition, and the process can more easily realize reuse of the recycled wastes.
Description
Affiliated technical field
The present invention relates to a kind of fiber reinforced thermolplastic composite material moulding new technology.
Background technology
The production technique of common fiber reinforced thermolplastic composite material goods generally all will be through making blank and two processes of moulding, this moulding process not only will store, transport blank, and waste of manpower, material resources, the energy and time cause the production cost height.
Summary of the invention
The present invention has overcome the deficiency of existing moulding process, the invention provides a kind of direct melting fiber reinforced thermoplastic composite material novel process, to solve the prior art deficiency, causes problems such as production cost height.
The technical scheme indication feed composition proportioning that the present invention solves its technical problem is: acrylic resin 50～65%, glass fibre 28～35%, silane type coupling agent particle 0.5～2.0%, span imide 0.5%～1%, UV light absorber 0.05～0.1%, antioxidant 1～2%, filler 5～8%; Adopt direct melt impregnation of fiber reinforced thermolplastic composite material and mould pressing process process combined method, will add once shaped in the mould after the thermoplastic resin and the direct fusion of preparing burden, concrete technology comprises:
1, batching: put into reactor after at first resin, glass fibre, coupling agent and other additive granules being mixed according to a certain percentage;
2, the infiltration of heating: Heating temperature remains on 200～220 ℃, is that reactor is heated to the resin melt temperature, stirs to reduce resin viscosity with agitator, increases the wetting property and the flowability of resin;
3, compression molding: soak into through certain hour, the back of when viscosity＜1Pas the feed liquid that mixes being weighed adds in the die cavity, the forming mould temperature is 80～90 ℃, the matched moulds pressurization makes the fused material be full of the die cavity of mould, rapid matched moulds pressurization 10～25MPa, get rid of unnecessary material and gas, under pressure, be consolidated into goods;
4, the demoulding: behind 30～50s, carry out the demoulding behind the speed cooling 20～90S with 5～7mm/s, ejection pressure is less than 20% of forming pressure, and the demoulding obtains the fiber reinforced thermolplastic composite material blank.
The invention has the beneficial effects as follows that moulding process has only the course of a single heating, energy consumption is low; Reduced middle-chains such as ingredient storage, transportation and preheating, saved energy consumption and artificial, production cost is lower; Product can be determined starting material and proportioning voluntarily according to the different needs of goods, batching degree of freedom height; The degree of wear to fiber in the moulding process is less, can guarantee the length of glass fibre better, makes end article have more excellent mechanical property and outward appearance; To the molding device wearing and tearing still less; The utilization again of waste material is reclaimed in easier realization.
Embodiment
Below in conjunction with specific embodiment to further detailed explanation of the present invention:
To produce the 1000kg thermoplastic composite is example, and its feed composition proportioning is: acrylic resin 60%, glass fibre 30%, silane type coupling agent particle 2%, span imide 0.8%, UV light absorber 0.1%, antioxidant 1%, filler 8%; Adopt direct melt impregnation of fiber reinforced thermolplastic composite material and mould pressing process process combined method, will add once shaped in the mould after the thermoplastic resin and the direct fusion of preparing burden, concrete technology comprises:
1, batching: at first will put into reactor after mixing according to a certain percentage through exsiccant acrylic resin 600kg, glass fibre 300kg, silane type coupling agent particle 20kg, span imide 8kg, UV light absorber 1kg, antioxidant 10kg, filler 80kg by said ratio;
2, the infiltration of heating: Heating temperature remains on 215 ℃, is that reactor is heated to the resin melt temperature, stirs to reduce resin viscosity with agitator, increases the wetting property and the flowability of resin;
3, compression molding: soak into through certain hour, the back of when viscosity＜1Pas the feed liquid that mixes being weighed adds in the die cavity, the forming mould temperature is 90 ℃, the matched moulds pressurization makes the fused material be full of the die cavity of mould, rapid matched moulds pressurization 20MPa, get rid of unnecessary material and gas, under pressure, be consolidated into goods;
4, the demoulding: behind the 40s, carry out the demoulding behind the speed cooling 60S with 5mm/s, ejection pressure is less than 20% of forming pressure, and the demoulding obtains the fiber reinforced thermolplastic composite material blank.
